Effect of design change on aerodynamic characteristics of a car

The vast majority of robots are controlled through the use of encoders that measure joint rotation. But even when encoders with very high levels of accuracy are used, the ability of robots to move to an absolute XYZ position and ABC orientation is limited by deflection, thermal expansion and manufacturing variation. Some applications, such as placement of a disk drive read head, require very higher levels of positioning accuracy that can only be achieved with a very expensive, special purpose robot. This challenge is being addressed with visual servoing technology that uses a vision system to acquire an image that determines the relative positions of the robot end-effector and the target.

“The concept of the hidden robot model is a powerful tool able to analyze the intrinsic properties of some controllers developed by the visual servoing community,” Sébastien Briot concluded. “Adams simulations have played an important role in validating our theoretical work on hidden robot models. The integration of Adams with Simulink through Adams/Controls eliminated the need for us to write complex equations for predicting the dynamics of parallel robots and also provided graphical results that gave us a better understanding of robot behavior.”

• Adams simulation accurately predicted position and orientation of the robot.
• Simulation played an important role in validating the theoretical work
• Complex equations are no longer needed to predict the dynamics of parallel robots

The configuration of cooling fans inside electronic devices is complex. This frequently results in generating large amounts of data when trying to represent the configuration accurately for fluid analysis calculations. To deal with this, engineers use the concept of the pressure-flow-rate (PQ) characteristics to simplify the calculation, although it has been pointed out that this simplification often becomes the source of errors. Professor Hajime Nakamura, from the National Defense Academy of Japan, has been exploring these issues pertaining to fan models for electronic devices and has discovered a more accurate model.

Simulating complicated wind flows around buildings and the surrounding environment used to mean conducting wind tunnel tests that required a long time, large-scale facilities, and skilled experts. Now, many of the experimental tests are being replaced by computational fluid dynamics (CFD) simulations. Combining these two approaches draws on the advantages of each and is commonly done in engineering today. But Mr. Tetsuo Matsuyama from WindStyle Corporation, who has used scSTREAM for many years, envisions additional opportunities for CFD. He explains how using scSTREAM proactively to interpret wind flow can change design processes and building management.

Reinforced plastics and composite materials are chosen more and more because of their improved performance regarding damping for NVH applications compared to current metals. Material specialists need to efficiently identify this mechanical characteristic which, like the stiffness and failure, is anisotropic and driven by local fiber orientations in the material’s microstructure. Moreover for NVH purposes, the frequency dependency must be clearly identified in order to provide accurate material models to design engineers.
