Comprehensive transmission durability assessment test method based on probability statistics

The invention relates to a comprehensive transmission durability assessment test method based on probability statistics, and belongs to the technical field of vehicle test methods. According to the invention, the technical problems that the damage effect on the shaft parts of the transmission device is small and the durability of the shaft parts cannot be effectively assessed in the durability test assessment of the whole transmission device in a fixed rotating speed-fixed torque test method taking a motor as power are solved; the test method can effectively examine the durability of gears and shaft parts in a complete machine test; according to the method, on the basis of a probability distribution calculation method, a feasible loading test method in the whole machine bench test is found in combination with the theoretical basis of dynamic load equivalence of the whole machine bench test, and the scientificity of dynamic load loading equivalence of the bench is effectively improved. 本发明涉及一种基于概率统计的综合传动耐久性考核试
