Aircraft bearing is the key transmission and supporting components in aircraft engine with high speed,high duty and high temperature circumstance.The evolution of wear state has an important influence on the tribosystem degradation of aircraft bearing during its service process.In order to realize the dynamic monitor of the wear state parameters of aircraft bearing testbed,the health evaluation of aircraft bearing tribosystem was studied by establishing a simulation and control system based on LabVIEW.The running process of aircraft bearing was simulated by the humanmachine interface(HMI),and the action command was executed by the driving system.The wear data of aircraft bearing was obtained by dynamic monitoring module.Based on the above process,high performance measurement and FPGA based advanced analysis was realized.According to the dynamic wear data chain,the NI soft motion technology was applied to simulate the actual operation condition and realize the advanced dynamic intelligent control system from the simple PID control.Experimental results indicate that the triboperformance measurement and control system of aircraft bearing testbed can collect the wear and friction information to reflect the health evolution process when aircraft bearing works in the complicated conditions,and realize the Dynamic performance evaluation of aircraft engine.
