Step Change in Design: Exploring Sixty Stent Design Variations Over Night

Traditionally, computer analysis has been used to verify the structural performance of a proposed stent design. The stent deployment process consists of multiple stages (e.g. crimping, springback, expansion etc.) which is highly non-linear inducing material plasticity and load transfer via component contact. A single structural verification assessment would require a couple of days to compute on a PC. This paper investigates how recent developments in Computer Aided Engineering (CAE) and computer hardware combine to facilitate the rapid exploration of many stent design variations. It is demonstrated that by utilising these technologies, over sixty stent design variables can be assessed overnight provides valuable design sensitivity information and an optimum stent geometry configuration. On an example baseline geometry considered the radial stiffness was significantly enhanced with an improvement in structural performance. This represents a step change in the CAE assessment of a stent design.

Optimisation Techniques Leading the Development of a Steering Wheel

The early application of structural optimisation in the design of automotive components streamlines the design process and at the same time significantly increases the potential of the final design achieving maximum performance. This paper details the use of optimisation techniques during the development of a steering wheel, to generate an optimised design for cross attribute performance. This was completed in the Altair HyperWorks environment as Altair HyperMesh combined with Altair OptiStruct enables the creation of a parametric model with a multitude of design variables (i.e. size, shape, displacement, stress and frequency) in order to satisfy NVH, manufacturability, durability and crash targets.

Automotive Weight Management Article

The automotive development process is still focused on objectives such as durability and crash safety, while weight is often limited to the very end of the design process. Through the establishment of the “Optimization Center” (OC) concept, Altair ProductDesign has developed an innovative design model combining performance features with weight reduction goals. This article describes the OC concept dealing with everything from the optimization of single components to an entire optimization process known as “CAE Weight Management”.

Structural Component Design Optimization for Additive Manufacture

Additive manufacturing (AM) technology enables the possibility of realizing highly efficient, optimized structural components with configurations not achievable using conventional manufacturing methods. The Altair and Solid Thinking toolsets provide advanced capabilities to design structural topologies to minimize weight and maximize other performance criteria. However, conventional manufacturing processes require application of design constraints, such as directional access for machining, in the optimization that limit the structural efficiency of the resulting design. AM can remove many of these constraints to allow for more efficient configurations under the applied loading conditions. Case studies show the potential to reduce weight up to 30% for components with applied bending and torsional loads by allowing increased complexity configurations that could only be manufactured additively.

HyperWorks Improves Development Processes in Automotive Industry

In 2008 PWO Germany (Progress-Werk Oberkirch AG) had to develop and produce a new steel made automotive cross car beam (CCB) for the dash board of a new car. PWO received the CAD model, the design space definition and other pre-defined standards of the component from the customer and developed and produced the fitting cross beam based on this information. PWO used the HyperWorks Suite to develop the component. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. HyperForm was used to check the production feasibility of the individual components and for metal forming simulation tasks. It was important for PWO to have a software suite available that could cover all simulation tasks within one graphical user interface and licensing system.

An Interview with Ben Farmer of Robot Bike Co. Discussing the Development of their R160 Bike with Altair

Robot Bike Company (RBC) is a new startup established in the UK by aerospace engineers and mountain biking enthusiasts who identified the potential of combining additive manufacturing technologies with carbon fiber to, in their own words, “create the best bike frames possible”. To deliver a customizable, lightweight, high strength bike, RBC’s frame was intended to be created from carbon fiber, a material very common in the industry. The carbon fiber tubes, as well as the bike’s other components and systems were to be joined by additively manufactured titanium ‘nodes’, manufactured based on the specification of individual riders. Altair ProductDesign’s engineering team was tasked with optimizing these joints, which included the head tube, seat post and chain stay lugs, to ensure they were as lightweight as possible and still able to withstand the forces of downhill mountain bike riding, all while being fit for the AM process.
