Studv On Simulation Loading Test Technology Of Tracked Vehicle Electromechanical Transmission

Tracked vehicle with electric transmission technology as an important part of the tracked vehicle new technology research,in power transmission,although the electric drive is more flexible and efficient compared with the traditional mechanical transmission,but the performance of the electric control system of tracked vehicle need being higher and higher.In order to develop the control algorithm and the electric system of the electric drive tracked vehicle,the test platform of the electric drive tracked vehicle also needs to have the condition of the model simulation test.With the development of computer technology and related electronic hardware,the road driving simulation test of electric drive tracked vehicle has been developed and perfected step by step.The first chapter introduces the technology of electric drive tracked vehicle and its research status,introduces the performance test of the electric drive tracked vehicle and the road driving simulation test.In the second chapter,the driving model of electric drive tracked vehicle is introduced.Including the tracked vehicle in the horizontal plane and on the slope of the driving model of condition,such as uniformly in a straight line driving,speed straight line travel,uniform steering;The analysis when considering the centrifugal force model under high speed steering.The third chapter introduces the design of Complex Pavement model.Including the design of simple moving track of the horizontal plane and the design of the road surface with the transition curve,the design of the road trajectory of the vehicle pitch angle,the complex road model design including the vehicle side rake angle and pitch angle.In the fourth chapter,the load of the measurement and control system of electric drive tracked vehicle is introduced.Including electric drive tracked vehicle control system building,electric inertia compensation calculation in road simulation test.The road simulation loading test with driving model and road model of tracked vehicle.Road model of field acquisition reconstruction and discretization of loading test.The fifth chapter summarizes the main content and research results of the paper,and the research contents are discussed.
