Reliable Sample and Order-Based Repeatable Analysis of Unstable Signal of Automobile Transmission

A system that can control theunstable running process of automobile transmission repeatedly and sample thesignal consistently is designed, the unstable signal of automobile transmissionwith changing rotate speed is sampled by this system, and analyzed by themethod of order to ascertain the best test position corresponding to the speed,then the system’s repeatability of test is identified. The results ofexperiment and analysis show that the system can control the repeatableexecution of unstable running process of automobile transmission stably, so theproblem of repeatable test of unstable running process is well solved, and thatthe unstable signal of automobile transmission is analyzed by order and theinformation of mesh order is extracted effectively, and the analytical effectis clear and stable.
