摘要
采用虚拟样机技术对轴向柱塞泵柱塞副进行仿真分析,介绍虚拟样机子模型,通过软件接口实现子模块之间数据传递,实现柱塞副仿真模型的液固耦合和刚柔耦合;建立试验平台,通过试验测试结果验证模型的正确性,证明轴向柱塞泵虚拟样机仿真平台对轴向柱塞泵设计有很强的指导作用.仿真分析柱塞泵负载压力等级、斜盘倾角以及柱塞副间隙对柱塞副性能的影响,表明柱塞副设计是限定轴向柱塞泵压力等级和最大斜盘倾角的重要因素,适当减小间隙油膜厚度可以降低柱塞副泄露损失和摩擦损失,并有助于提高柱塞副油膜承载能力.
Simulative analysis of piston-cylinder pair of axial piston pump was performed with virtual prototype technique.The sub-models of virtual prototype were introduced.The data transfer among the sub-models was realized with software interface.The liquid-solid coupling and rigidity-flexibility coupling of piston-cylinder pair model were achieved a co-simulation model called as virtual prototype.Then several related test rigs were built up.The correctness of the model was verified by the measurement result of the test and the experimental result also demonstrated that the virtual prototype simulation could be used to guide the design of axial piston pumps and to analyze the influence of loading pressure,inclined angle of swash plate and clearance between piston and bushing on the performance of piston-cylinder pair.It was shown that the design of piston-cylinder pair was the key influencing to factor limit the pressure level and maximum swash plate angle.A slight reduction of the thickness of oil film between piston and cylinder could result in reduction of leakage and friction of piston-cylinder pair and improve of the bearing capability of the oil film.
