摘　　要：为提高双离合自动变速器的工作性能,在分析自主研发的七速对置双离合自动变速器电液控制系统工作原理的基础上,利用AMESim软件,研究换挡过程中同时工作的液压缸间的相互影响及其影响因素,并通过选用合适的液压源参数的方法来降低相互影响程度。仿真结果表明:双离合自动变速器的电液控制系统中,两离合器作动油缸间的相互影响程度最大,并且两作动缸活塞截面积(活塞行程不变)、泵的排量、电机转速、蓄能器容积、油道水力直径等都会影响两缸相互影响的程度。In order to improve the performance of dual-clutch automatic transmission, on the basis of analyzing the working principle of the self-developed seven-speed double-clutch automatic transmission’s electro-hydraulic control system, the interaction between working hydraulic cylinders and its influencing factors were studied with AMESim software. By selecting appropriate hydraulic parameters, the degree of mutual influence was reduced. The simulation results show: in the electro-hydraulic control system, the interaction between the two clutch cylinders is the largest, and the piston cylinder cross-sectional area(piston stroke unchanged), pump displacement, motor speed, accumulator volume, oil channel hydraulic diameter will affect the degree of mutual influence of the two cylinders.
