摘　　要：由于双离合器液压系统具有强非线性特征,其模型的精确建立对于掌握液压系统特性和实现精确控制有很大影响。分析了液压系统的核心部件—直接控制电磁阀的结构原理,并对其进行分解建立了精确的系统模型。通过试验验证可知,仿真结果与试验测试结果吻合,证明该模型正确。For the strong nonlinearity of dual clutch transmission （DCT） hydraulic system, precise establishment of the model has significant impact on understanding hydraulic system properties and precise shifting control. Structure principle of the direct control solenoid valve, the core part of the hydraulic system, is analysed in this paper, and a precise system model is built. Test results indicate that the simulation results coincide with test results, which proves the correctness of this model.
