Computational Analysis of Quadriceps Tendon Force Following Total Knee Replacement Surgery Leads to Improved Patient Knee Flexure
Anterior knee pain is a significant complication following total knee arthroplasty (TKA) surgery. The inability to freely extend/flex the knee has a crucial influence on patients daily activities including walking, lifting and rising from a chair. This knee movement inability is one of the most common indications of needed TKA procedure revisions. Poor sizing during surgery of the patellar knee component – a “button-like” element that increases the mechanical advantage of the
extension force. The research biomechanics group in the Department of Bioengineering at Clemson University has evaluated the effect of the patella-button thickness on the variation of the magnitude of the quadriceps tendon force by applying HyperWorks-based finite element analysis.

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.

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.

Better Indoor Climate thanks to Simulation and Optimization
Kampmann GmbH is an internationally leading specialist for heating, cooling, air-conditioning and integrated building automation. Within their virtual development process they are using the Altair HyperWorks® software suite, in particular AcuSolve®, the CFD solver; OptiStruct®, the suite's FE-solver and an optimization tool; and HyperMesh® for modeling and meshing tasks. For plant control design, Kampmann is currently considering solidThinking Activate®, a mapping software for control systems. Thanks to simulation, Kampmann engineers are now able to answer questions regarding the internal processes of the system, which are difficult, if not impossible, to study through physical testing.

From Incremental Change to Full Design/Validation Leap: A Multidisciplinary Approach to Optimize Safety and Crash Performance
Heavy-duty mining trucks at Hitachi are designed to meet ISO ROPS and FOPS safety requirements, while structures must be as lightweight as possible. The presentation will discuss Hitachi’s design and simulation approach, which consists of an integrated multidisciplinary analysis process. Dynamic analyses, multibody dynamics simulations, including flexible bodies and dynamic simulations are methods applied to optimize performance and vehicle safety.

The author will present examples such as the optimization of a trolley support structure, a kinematics model of a 100-ton truck and the analysis of a trailing arm. Finally, the author will share his thoughts on the important subject of how simulation can better impact the design.

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?
