Abstract
The purpose of this paper is to give a description of using the new type Suspension Parameter Measurement Device. The design philosophy and specifications are elaborated on in another SAE paper entitled “Design of a New-Type Suspension Parameter Measurement Device”. The importance of using this new machine will be addressed in this paper.
Because of the ease of use for this new device, testing can be accomplished in hours. To check repeatability, repeat testing can be done in a short period of time. This rapid testing is the main advantage of the new generation of SPMD's. The new SPMD collects raw data from transducers. All data are stored in the computer. Some are used directly to generate graphic outputs. Some are utilized to calculate wanted parameters. Graphs are generated so that some characteristics can be scrutinized. Parameters can be presented either by points or by cross plotting in graphs. Cross plotting is a useful tool for checking correlations between parameters or obtaining other parameters. Examples of results are presented and discussed.
