摘要

本文对重型自动变速器换挡控制液压系统进行了设计，旨在统一和规范设计方法。该系统是根据液压元件的二元逻辑特性设计的。此外，为了满足扭矩传递的要求，降低能耗，设计了油压供应和流量调节系统。建立了液压系统的数学模型和仿真模型，对其性能进行了分析。最后，利用遗传算法对系统进行了优化（在AMESim环境下）；结果表明，各齿轮的主压力控制在合理范围内；换档离合器的压力和压力响应时间都减小了。此外，液压系统的功率损失得到了显著改善，提高了整个液压系统的实用性能。

Logic design method and optimization of hydraulic system for heavy-duty automatic transmission

In this paper, the shifting control hydraulic system of the heavy-duty automatic transmission was designed, aiming to unify and standardize design methods. Said system is designed according to the binary logic characteristics of hydraulic components. In addition, to meet the torque transmission requirements and reduce the energy consumption, both the oil pressure supply and flow regulating system were designed. Mathematical and simulation models of the hydraulic system were established to analyze its performance. Finally, the genetic algorithm was used to optimize the system (within the AMESim environment); the results have shown that the main pressure of each gear was controlled in a reasonable range; both the pressure of shift clutch and the pressure response time was reduced. In addition, the power loss of the hydraulic system was significantly improved, which improve the practical performance of the overall hydraulic system.
