A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments
The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

NEVS Uses Simulation Driven Innovation in Car Body Design
Dr. Lars Fredriksson, Business VP – Simulation Driven Innovation at Altair presenting on behalf of NEVS at the 2017 European ATC.

The automotive industry is experiencing ever increasing requirements on new vehicles from all directions. Still, development cycles must be shortened and development costs reduced. Early concept development is a project stage where change costs are low and design freedom large. Thus, improvement of early concept development to mature designs faster and with better design balance must be a key goal of vehicle development.

ADAS Simulation Under Severe Vibrations
Automotive radars are becoming standard equipment on vehicles. Their purpose is to adjust the distance between vehicles and/or alert the driver when dangerous situations arise. Several antenna architectures are used to cover the different safety functions in complex bumper/car chassis environment where the side
effects become more and more significant on the radar performances. Hence, automotive radar integration process becomes a very important
topic. Weak radar integration will generate gain loss, high side lobes levels and angular errors. Those degradations will impact the radar range,
the main radar axis (BSE) and the radar detection quality (resolution, ambiguity, discrimination).

Predicting the Dynamics of Mechanical Systems in the Automotive Industry
The application of CAE tools to help design and develop mechanical systems in the automotive industry is a widely accepted practice. This paper highlights various applications of these tools, in particular, the application of MotionView and MotionSolve from Altair Engineering. Each example demonstrates the advantages of using such tools to work rapidly and seamlessly within the general design process. This results in the development of innovative designs to face challenging problems in a short time frame.

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 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.

Scania Customer Story
Squeak and rattle phenomena are studied in the automotive industry in an attempt to reduce the cabin noise and as a result, give a better ride quality and comfort to occupants. In the case of Scania’s Cabin Development Department, this kind of simulation was not performed historically. The team had to rely on tolerance calculations as well as the choice of materials to reduce the risk of squeak and rattle. To reduce development time and cut down on iterative changes, a desirable solution was identified that enabled a simulation-driven design process during the early stages of the cabin development cycle.
