When the mechanical engineers are designing a new chassis or a new security device for the automotive market, they base their analysis on existing theoretical schematics and structures behaviors. The validation processes are very important to match the theory and the reality. In studying the movement structure in real situation, they definitively settle it. The customer need a displacement sensor to look into the structure chassis rigidity and behavior or the part in motion during the test.
The LVDT displacement sensors will be used as a primary measurement on shock absorber. They will combine roll holding, absorber rigidity coefficient and movement of the absorber devices on each wheel. An embedded computer will be placed to cover the acquisition and sampling. The electronic must register as much measurements as possible in using high readings rate.
Analogue series with universal joints has been selected to simplify the mounting process. The Robustness of the stainless steel satisfy the specifications of the dampers application. The direct analogue output will be kept by a National Instrument device to insure the quality of the acquisition.
