Northwestern University Success Story
Using HyperWorks for Teaching Computational Optimization Methods in Engineering Design at Northwestern University

Optimizing Cooling Passages in Turbine Blades
Turbine blades have internal passages that provide cooling during operation in a high
temperature engine. The design of the cooling passages is critical to achieve near uniform
temperature of the blade during operation. The temperature of the blade is dependent on the thermal properties of the blade material as well as the fluid dynamics of the air circulating in the cooling passages. Computational optimization methods have successfully been applied to design lighter and more efficient structures for many aerospace structures. An extension of these techniques is now applied to guiding the thermal design of a turbine blade by designing the optimal cooling passage layout. Optimization methods will be applied to determine the optimum pattern of the cooling passages and then to optimize the size of the individual cooling passages. The goal is to produce a more thermally efficient turbine blade design that will produce blades with longer lives and better performance.

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.

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.

Snap-Fit Optimization for Achieving Desired Insertion and Retention Forces
Snap-fits are ubiquitous engineering features used to quickly and inexpensively assemble plastic parts. The geometric, material, and contact nonlinearities associated with snap-fit problems can present modeling challenges. Quasi-static solutions with explicit solvers are commonly used to analyze snapfits; however, OptiStruct’s nonlinear solver now possess the ability to solve these highly nonlinear problems implicitly. The first part of this study discusses an effective approach to using OptiStruct for the implicit finite element analysis of snap-fits. Once an accurate simulation model has been created, engineers typically make design changes in order to achieve desired insertion and retention forces. The second part of this study details how HyperMesh morphing and HyperStudy can be used to optimize the snap-fit design, resulting in desired insertion and retention forces while minimizing mass and ensuring structural integrity. The approach documented in this report can reduce the design time, material use, and failure rate of snap-fits used in industry.

Biomedical Research at the Scripps Clinic: Modeling Orthopedic Implants with Altair HyperWorks
Every year, countless people — regardless of their age or level of physical activity — begin to experience the effects of osteoarthritis, a degenerative joint disease. As we age, the cartilage that cushions the joints begins to deteriorate. The head of the adjacent bones begin to break down from the friction, causing pain in the joint. When the condition worsens and non- surgical remedies are exhausted, surgeons may recommend joint replacement.

Typically, titanium alloy implants are lined with plastics that act as cartilage and are fixed in place with cement or screws by the surgeon. The implants can give patients a new lease on life, dramatically reducing pain and improving mobility. However, questions naturally arise in the patient’s mind: How much range of motion will I have in the new joint? How much strength will I recover? And how long will the new joint last?

Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance
The automotive industry, in its constant quest for weight reduction, is increasingly considering composite materials as a substitute for sheet metal components to meet future fuel consumption standards. However, composite forming processes are expensive and difficult to control because of the complexity of the material behavior with fiber and matrix layers or plies and its dependency on many parameters, such as non-linearity of tensile stiffness, effect of shear rate, temperature and friction. Hence, numerical simulation could be a viable approach to predict material behavior during composite forming. The objective of this study is to highlight capabilities of RADIOSS™ to simulate forming simulation of composite plies made from woven fibers, each ply modeled as a layer of woven fibers along two directions of anisotropy, warp and weft. For validation the well-known double dome model published in NUMISHEET’05 proceedings is used. The compared result is the shear angle after stamping that is, the final angle between warp and weft fibers, at several prescribed points on the ply. The variation of this angle has a strong impact on material characteristics which severely deteriorates when a critical value is reached. Hence, a study on crash simulations is performed, after mapping fibers angles from stamping simulation.

Multi-physics Electric Motor Optimization for Noise Reduction
In an electric machine, the torque is generated by electromagnetic forces which also create some parasitic vibrations of the stator. These vibrations excite the mechanical structure on which the motor is fixed and generate sound. When designing the electric machine, this aspect has to be taken into account from the start since it depends on the harmonic content of the currents that feed the machine, on the shapes of the rotor and stator, and on the interaction of the electric frequencies with the natural mechanical modes of the structure.
To simulate this phenomenon, a coupling between electromagnetic calculations and vibration analysis has to be set-up. Some optimization procedure can also be added in order to reduce the noise.
In what follows, it is shown how Altair HyperWorks suite; specifically FluxTM, OptiStruct®, HyperMesh® and HyperStudy® products have been successfully used to perform a multi-physics optimization for noise reduction in a fuel pump permanent magnet motor.

Programmable, Open-Architecture HyperWorks Helps Toshiba Design Smaller Hard Disk Drives to Meet Market Demand
Toshiba Digital Network Company, faced with increasing global competition in the hard disk drive (HDD) marketplace, set out to create an advantage through the redesign of their existing HDD product(s). To support this effort, Toshiba partnered with Altair Engineering to automate its design process. This was accomplished by leveraging HyperWorks powerful modeling, visualization and optimization software applications with Toshiba’s proprietary solver for fluid dynamics. The specific goal was to optimize the air bearing surface (ABS) of the HDD’s magnetic head slider. This unique product development process resulted in minimizing the flying height as much as possible while considering its stability. This, in turn, reduced the overall size of the HDD and increased its recording density. In addition, the new design was brought to market in significantly less time than with Toshiba’s traditional design process.


Reducing Weld Distortion by 93% with HyperStudy
Gestamp Tallent Ltd is a world class designer, developer and manufacturer of cutting edge, chassis structural and suspension products, body in white structures, modules and systems for the automotive industry. Gestamp used the BMW MINI front subframe tower to demonstrate the weld distortion optimisation approach. The tower is particularly susceptible to distortion due to its tall and thin dimensions. The objective of this optimisation was to minimise the distortion of the tower measured by the displacement of the top of the tower as the weld sections cool. In order to further investigate weld removal optimisation they chose HyperStudy.

Weld Distortion Optimisation using HyperStudy
Distortion induced in parts due to the cooling of welds complicates automated manufacturing lines in the automotive industry. The resulting deformation leads to additional investment such as end of line machining to correct affected assemblies. Utilising optimisation software a welding pattern can be found which retains the intended performance of a part while reducing the distortion induced from welding. Weld locations may be optimised alongside welding sequence to allow process requirements to be considered within the early design stage. This leads to high performance, low distortion assemblies which can ultimately be manufactured at the lowest possible cost.
