摘要

静压-机械双流传动（HMT）由静压传动和机械传动并联而得,兼具静压传动传递转矩大和机械传动效率高的优点,复合式静压-机械传动（DHMT）由两套双流传动并联而成。对DHMT系统及各组成模块进行了动力学建模,根据建立的动力学模型提出了DHMT系统的换挡调控策略,基于AMEsim和Simulink搭建了DHMT的联合仿真模型,最后对仿真结果进行分析并验证了换挡调控策略的正确性。

Abstract

The hydro-mechanical transmission（ HMT） is obtained by connecting hydraulic transmission and mechanical transmission in parallel. It has the advantages of high torque of hydraulic transmission and high mechanical transmission efficiency. The dual hydro-mechanical transmission（ DHMT） is connected by two sets of double flow. The components of the DHMT system are modeled and the shifting control strategy of DHMT system is proposed based on the established dynamics model. The co-simulation model of DHMT is built based on AMEsim and Simulink. Finally,the simulation results are analyzed and the correctness of the shifting control strategy is verified.
