摘  要：
为提高液力传动系统性能,研究了发动机与液力变矩器匹配特性。按照功率分流形式,将液力传动系统划分为两种典型结构模型,在对两种结构模型进行图论化抽象的基础上,利用Python语言开发出通用的传动系统动力学平衡方程组自动列写并求解,并编制了发动机与液力变矩器匹配计算的计算机程序。结合计算实例,将2种结构模型在不同路况下的匹配结果进行了对比,结果显示前分流系统发动机与液力变矩器的匹配特性受外载荷影响作用明显,因此不能忽略负载变化而单独研究这类液力传动系统的匹配特性。

摘  要：
To improve the performance of hydraulic transmission system,a study on the matching performance of engine and hydraulic torque converter was conducted.According to the power split-flow form,hydraulic transmission systems were divided into two classical structure modals.With the two structure modals were abstracted according to graph theory,a computer program was developed using Python language,which could finish auto-derivation and auto-solving,and finish the matching calculation of engine and torque converter.Combined with a matching calculation example,a comparison study of the results of the two structure modals under different road conditions was carried out,which showed that the matching performance of engine and hydraulic torque converter in the hydraulic transmission systems with front power split-flow was obviously influenced by external load,and the load effect had to be considered in the study on its cooperating performance.
