A Comparative Aerodynamic Study of Commercial Bicycle Wheels Using CFD

A CFD methodology is used to study the performance of several commercial bicycle wheels over a range of speeds and yaw angles. The wheels studied in this work include the Rolf Sestriere, HED H3 TriSpoke, the Zipp 404, 808 and 1080 deep rim wheels and the Zipp Sub9 disc wheel. Wheels are modeled at speeds of 20mph and 30mph, in contact with the ground, using Reynolds-Averaged Navier Stokes (RANS). Drag, vertical and side (or lift) forces are reported for each wheel. Turning moments are also calculated using the resolved side forces to examine aspects of stability and maneuverability. Drag and side forces over the range of yaw angles studied compare favorably to experimental wind tunnel results. The previously reported unique transition from downward to upward acting vertical force on the Zipp 404 wheel for increasing yaw angles is observed for all deep rim wheels and the disc wheel studied here. Wheels were also modeled at a critical yaw angle of 10 degrees using Delayed Detached Eddy Simulation (DDES) to examine the transient aspects of flows around moving bicycle wheels. It is hoped that a more complete comprehension of these results will lead to improvements in performance, safety and control of bicycle racing wheels used by amateur and professional cyclists and triathletes.

An Aerodynamic Study of Bicycle Wheel Performance Using CFD

A methodology is presented to apply CFD to study air flow around a rotating bicycle wheel in contact with the ground. The bicycle wheel studied here is an accurate geometrical representation of a commercial racing wheel (Zipp 404).

Automotive Modal Testing Support and CAE Correlation Using Altair HyperWorks

To derive the natural frequencies and mode shapes of a given structure, the test Engineer has to decide on excitation positions that will efficiently excite all the modes of the structure in the frequency range of interest. Excitation positions are usually decided upon from experience or trial and error methods which can be time consuming and still not capture all of the modes in the selected frequency range. Using Altair HyperStudy and Radioss (bulk), Pre-test CAE analysis has been carried out to identify effective excitation positions before the commencement of modal testing, thereby significantly reducing pre-test lab time.

Composite Optimisation of a Formula One Front Wing

This paper will show the application of a 3-stage approach to designing the optimum composite structure for a front wing on a Formula One car using Altair OptiStruct 9.0 Continual development of aerodynamic components is normal practice in the world of Formula One and the time taken to respond is paramount if a team is to be competitive.

Hawk T Mk2 - Arrestor Barrier (BAN MK2) Engagement Analysis

As the UK Ministry of Defence (MoD) Design Authority for Aircraft Arrestor Barrier Nets, AmSafe products are used to stop aircraft from over-running the end of the runway. The British Arrestor Net (BAN) Mk2 is suspended across the runway over-run area by two electrically driven stanchions and raised or lowered by remote control from the Air Traffic Control tower. This paper describes the process and results of a FE analysis of the engagement of the Hawk T Mk2 aircraft into a Type A Barrier (BAN Mk2). The analysis was performed using RADIOSS, an advanced non-linear explicit Finite Element solver.

Rapid Airbag Folding Technique for Side Curtain Airbag

TECOSIM has developed techniques which can shorten the folding & packaging process time to a few hours and still achieve the essential airbag deployment performance. We will present methods which rapidly fold a free mesh and allow for rapid shape changes for a detailed folded model. These methods can significantly reduce the turnaround time to incorporate design changes into the working CAE model for side impact and OOP [Out Of Position] studies. This technology can integrate airbag development further into the virtual world to allow ‘CAE led’ design of airbag profiles, chambers and seam lines to be established early in the design phase and establish a fully folded deployable airbag for all virtual phases.

Evolutionary Design in Chassis Technology

This paper details the use of the Thyssenkrupp eDICT process for the design of sheet metal chassis components. eDICT (evolutionary design in chassis technology) is an innovative structured process flow for the design of optimal structures. eDICT uses the optimisation capability of Optistruct with a set of custom tools to guide and translate a design into a production feasible sheet metal solution. Fundamentally it reverses the usual design loop of CAD first then CAE assessment. The function is used to determine the design and the form follows. On recent projects eDICT has produced 25% mass reductions compared to the current series design. eDICT is also able to reduce development times and resource with an efficient solution production right from the outset.

The CAE Driven Safety Development Process of the New Ford Fiesta

The new Fiesta is about premium feel of a larger car, delivers a new level of safety, driving quality and efficiency. The new Fiesta will be a great contribution towards sustainability and cost effective motoring. The first thing to notice is the design, but the vehicle performance and body structure attribute behaviour are the specific highlights to point out in this presentation. The attribute performance is not based on coincidences; the performance is a result of state of the art engineering work. Especially the safety performance in EuroNCAP.

Targeting Composite Wing Performance – Optimising the Composite Lay-Up Design

This paper shows how Altair OptiStruct, part of the HyperWorks suite, is used to provide a complete solution when designing with laminated composites, taking the design through concept stages to producing the final ply lay-up sequence. The technology is applied to the design of a laminated wing cover to produce a mass optimised design which meets the requested structural targets.

HUMOS - An FE Model for Advanced Safety and Comfort Assessments

Biomechanics modelling is becoming increasingly accepted as a tool for enhance assessment of vehicle safety, in particular in the field of injury assessment and virtual testing. Firstly, a generic RADIOSS model for safety applications (HUMOS2) is presented and applications are demonstrated. Important tools associated with the scaling, and positioning of the model is also described. Secondly, an innovative model for scaling of human organs (individualization) is presented. The method which employs optimization techniques, identifies critical (optimal) anatomical control points which allow for a best scaled model of the HUMOS2 representing an individual. Finally, some remaining challenges for future human models are discussed and solution paths are described.

Delivering Innovation and Intelligence in Product Design

Packaging designers must constantly inject innovations to attract consumers in a constantly evolving and highly competitive market. Keeping ahead of the competition by bringing new and exciting products to market faster whilst maintaining quality, presents a major engineering challenge. A new packaging development process is described, which introduces advanced automated simulation and optimization technology right from the concept development phase. Detailed predictions of primary, secondary and tertiary packaging performance are made possible through use of advanced simulation technology. Design optimization is then employed using the modelling as a virtual testing ground for design variants. The approach provides clear design direction, an opportunity for wider experimentation, helps to improve performance and reduces uncertainty in the development process.

Application of Optimisation Tools to the Design of Advanced Carbon Fibre Bicycle: FACTOR 001

FACTOR 001 is the result of a creative project by BERU f1systems to explore the transfer of design approaches, technology and materials from Formula One to a groundbreaking training bicycle. The design brief did not require the bicycle to comply with existing technical regulations, which resulted in great freedom during the design process. This paper details how OptiStruct Optimisation tools were used to help generate efficient lightweight solutions for the design of complex carbon fibre components. Free-size optimisation was used to generate laminate boundaries, ply thicknesses and fibre directions, which met stress and displacement requirements. Physical testing carried out on manufactured parts highlighted the accuracy of the FE models and demonstrated the advantages of incorporating OptiStruct Optimisation tools in the design process.

The Use of MBD Modelling Techniques in the Design and Development of a Suspension System

This paper describes the use of Multi-body Dynamics (MBD) modelling techniques in the design and development of a suspension system for a novel autonomous vehicle. The general approach and philosophy is described, whereby MBD techniques are used in conjunction with an independent (parametric) whole vehicle handling simulation. This is supplemented with examples, showing how MotionSolve was used (in tandem with CarSim) to develop the suspension elasto-kinematic geometric properties to meet specific cascaded targets, to optimise a weighing strategy, to predict forces under a variety of quasi-static and dynamic loads, and to estimate response to track inputs.

Fighting Knee Pain with Finite Element Modeling

The Musculoskeletal Biomechanics Research Laboratory at USC, is using HyperWorks to investigate why so many people are incapacitated by knee pain when others are not. This is a tough, intractable issue for people with arthritic knees since there is no cure for arthritis today. Early detection can help and is the focus of USC’s work. (HyperMesh is used to create finite element models to analyze stress on the cartilage of the joint.)
