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?

Accelerating Product Development through Process Automation

HyperView Automation for Post-Processing Cell Phone Drop Simulations

The cell phone design cycle within Motorola has matured to the extent that it is standard operating procedure to analyze several concepts of a specific model before physical parts are ever made. With the use of HyperWorks tools and the speed of current compute systems, pre-processing and number-crunching are no longer the bottlenecks in analyzing full assemblies during drop situations. The most time-consuming part of the analysis cycle for drop simulations has become post-processing. It is common in the analysis cycle to look at the results of 10 or more drop orientations for each concept. Each cell phone assembly is large enough that it manually takes a half- to a full day — depending on the drop orientation — to look at all the parts of interest. By teaming with Altair, HyperView has been customized to automatically produce a web-based report for a drop orientation in about 45 minutes. The report can be accessed by any member of the design team and provides a much quicker method for focusing on the critical components that need attention.

CAE Process & Data Management Using Altair Hyperworks Solution

Computer-aided engineering plays a significant role in the product development process. However, with the growth in the number of simulations performed, and in the absence of process and data management tools to track these simulations, inefficiencies start creeping into the CAE process. Altair Data Manager (ADM) is a pioneer tool in addressing this need. With this insight, the CAE group at Eicher Motors Ltd. decided to implement the ADM tool before process management and data migration became a Herculean task. Eicher CAE users wanted the ADM system to help them manage the complete CAE process and improve CADCAE integration. That included automated assembly buildup of batch-meshed components; automated part library buildup; analysis iterations management; faster and consistent report extraction; centralized data storage without any data duplication; and efficient sharing of results and reports across the organization.

Sheet Metal Transfer Simulation Using Altair HyperDieDynamics

The sheet metal part transfer process in high-volume transfer press is a critical phase of stamping manufacturing operations. Thus, understanding the dynamic behavior of sheet metal during transfer from die station to station becomes an urgent task in the tooling design phase.

The newly developed Altair HyperDieDynamics is a unique tool to analyze sheet metal transfer dynamic behavior through its intuitive graphic user interface and engineering intelligence. By introducing the flexible body property and the virtual model of the stamping press line, users can easily conduct a panel transfer dynamic analysis with MotionSolve, and visualize the in-motion blank deflections, accelerations and resultant forces. It is also a useful analytical tool to improve automation tooling design and transfer motion operational parameters.

The technology allows the mass to be minimized by the removal or addition of plies of various discrete orientations whilst satisfying the structural intent of the component. For the rib structure assessed, the structural constraints consist of limits placed on the displacement, stress (i.e. ply failure index) and buckling behaviour.

Driving Million Dollar Savings at Ford using Structural Optimisation

The automotive business is a very competitive industry and in today’s markets, leading manufacturers are keen to find ways of reducing costs without compromising either quality or performance. This paper will cover the process of applying OptiStruct software to the re-development of a high volume and high cost plastic PAS (Power Assisted Steering) pump bracket into a much cheaper aluminium alternative. The outcome of this was a lighter, stiffer and cheaper replacement bracket that had the potential, based on the current production engine volumes, to save Ford Motor Company over $1.1 million a year.

Simulating the Suspension Response of a High Performance Sports Car

The use of CAE software tools as part of the design process for mechanical systems in the automotive industry is now commonplace. This paper highlights the use of Altair HyperWorks to assess and then optimize the performance of a McLaren Automotive front suspension system. The tools MotionView and MotionSolve are used to build the model and then carry out initial assessments of kinematics and compliance characteristics. Altair HyperStudy is then used to optimize the position of the geometric hard points and compliant bush rates in order to meet desired suspension targets. The application of this technology to front suspension design enables McLaren Automotive to dramatically reduce development time.
