Computer Aided Design of Suspension Mechanisms

Automobile suspension mechanisms have to date been designed using two-dimensional graphic oriented methods. Computer-aided design has allowed many two-dimensional mechanisms to be designed much more accurately. However, this has not translated to suspension mechanisms because these mechanisms are not two-dimensional but instead three-dimensional.

Sense Element Pump Ripple Fatigue

Aerospace sensor technology is plagued by the balance between sensitivity and durability. As devices become more fragile in the pursuit of achieving higher accuracy they find themselves torn apart in the process. Hydra-Electric solves this using a special sense element of stainless steel construction capable of withstanding the harshest pressure spike environments without the use of a snubber. Using finite element analysis, it was revealed that near infinite fatigue life is achieved even in high pressure applications. This demonstrates the superiority of a stainless steel flexure sense element over conventional piezoresistive silicon (PRT).

Survival of the fittest - the process control imperative

In tough times, manufacturers focus on reducing their operating costs, but may not be able to afford to spend their way out by buying more productive machinery. With that pathway closed, what are the opportunities for radically reducing costs without replacing existing machines? Where can we:

Risky Business: Why Excluding Suppliers from Your Quality Processes Could Cost You

Suppliers play a major role in bringing products to market. This means that the product received from suppliers must be of the highest quality and level of safety possible—this is a must because stakeholders not only rely on their suppliers to help bring products to market, they also rely on them to help maintain their brand image. In this White Paper, you'll learn how to incorporate suppliers into your quality and compliance activities, resulting in a greater level of assurance.

Traceability Best Practices for Systems Engineers

Serious situations: In the middle of a project, your best customer changes a high-level business requirement. How will this change impact the system spec your engineers are working on right now? How will it impact scope for the upcoming release?

Nonlinear Model Predictive Control

This whitepaper presents an automatic workflow for implementing Model Predictive Control (MPC) controllers. The process uses MapleSim to generate a model of the system, whose dynamic equations are then extracted using Maple. Next, Maple is used to formulate the MPC problem, and generate the solver, which it automatically converts into the C code of the MPC controller. The advantage of using Maple is that the required procedures and their corresponding derivatives are computed and optimized whenever there is a change in the dynamic equations. The use of Maple saves time, removes human error, and produces highly optimized controller code.

Cost-effective Solutions for Audio Testing

The universal popularity of mobile devices presents potentially unprecedented growth for device makers. As the user base evolves, multimedia quality features increasingly as a major determinant in market dominance. Accordingly, integration of electro-acoustic components (i.e. receiver, speaker and microphone) into home use and industrial applications is becoming more of an industry mainstay every day. With audio quality thus recognized as a key consumer consideration, providers must maximize the effectiveness of audio testing in their manufacturing process. This article discusses how high-resolution dynamic signal acquisition modules can serve as a low-cost replacement for existing sound cards while meeting all testing requirements for high-profile mobile devices.
