Study on information fusion method by contamination analysis in hydraulic system

摘要

The oil monitoring on the Power-shift Steering Transmission (PSST) of armored Tracked Vehicle road tests are carried out to control the contamination in hydraulic system and avoid the PSST's deadly fault caused by oil contamination. The oil was analyzed by the Portable Oil Diagnosis System (PODS), which can show the large quantity of every particle size. The information is fused by principal component analysis, which is developed from ideals of dimension reduction in multivariate analysis. The result shows that this method can find the key information from the large information, while which can offer the theory and test proof for designer how to select the filtration ratio and to control the system's contamination in process of product design.
