Road Load Spectrum Collection and Analysis of AMT Actuating Mechanism
Road load spectrum is not only the prerequisites of fatigue reliability analysis and test of AMT(Automated Manual Transmission) actuating mechanism, but also the input and boundary conditions of CAE(Computer Aided Engineering). Based on analysis of AMT motion and force, the measuring points of road load spectrum are determined, and the accelerometers and strain gauges are installed. Then the road load spectrum of AMT actuating mechanism is collected on Xiangfan Automobile Proving Ground according to related standards. At the same time the acquired road load spectrum is analyzed, such as pretreatment, repeatability checking and statistical analysis. The results indicate that the acquired road load spectrum is well reliable and repeatable, which provides effective basic data for design, analysis and verification of AMT actuating mechanism.
