When electronic vehicle systems fail, itís often not the fault of microcontrollers, memories or integrated circuits. By watching for some of the following problems, designers can often boost reliability of end products, especially in automobiles.
Minimize connections. Thereís a high correlation between reliability and the number of electrical connections made at an assembly plant. A dashboard with ten connections, for example, is likely to be more reliable than one with 50 connections.
Make sure wires donít rub against sharp pieces of metal.†
Ensure connections go together with an audible snap. If assemblers hear the snap, they know itís connected.
Design in reliability at the beginning. Usually, if a car starts out reliable in its first model year, it stays that way.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry ďto fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].Ē
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
