Modeling And Emulate On The Sleeper And Seat Of Passenger Car Test System With Electro-Hydraulic Servo Controlled

The sleeper and seat of accommodation train test system with Electro-Hydraulic Servo Controlled integrates with much technique such as mechanic, electricity and hydraulic. It was applied broadly because of many characteristic. It is not only high in the power-weight ratio and large in the load stiffness and applied force but also agile in electric system and high in precision.Passenger's requirements about accommodation train become more and more strict.They hope the accommodation train have good comfort capability and security capability.However,the traditional accommodation train can't satisfied the requirements. In order to satisified the requirements,at the same time, meet the sleeper and seat of accommodation train itself's ability,therefore,I make a study on the sleeper and seat of the accommodation train test system with Electro-Hydraulic Servo Controlled.The modeling and emulate on the sleeper and seat of accommodation train test system with Electro-Hydraulic Servo Controlled is presented. At first the dynamic mathematic model is create in the light of the known dimensions and structure. Then base on the mathematic model, dynamic analysis of the system is studied by drawing the open-loop bode , closed-loop bode diagram and step response curve using the analysis and calculating function of Matlab .The influence factor on frequency character, steady and performance of the system is also analyzed.
