摘要
利用Excite_TD软件构建了本田125 mL单缸四冲程汽油机配气机构运动学与动力学模型,通过分析多项动力加速度函数(POL)与分段加速度函数(ISAC)凸轮型线设计方法的性能指标,选择ISAC优化设计可变循环往复活塞式发动机(VCRPE)二冲程与四冲程工作模式的进、排气凸轮型线。为了验证凸轮型线设计的合理性,利用SolidWorks构建并分析了相应配气机构的多体动力学模型,对比Excite_TD和SolidWorks模型的动力学分析结果表明,两者分析数据吻合较好,验证了凸轮型线优化设计的准确性。
The kinematics and dynamics simulation model for valve gear of HONDA 1 25 mL sin-gle-cylinder four-stroke gasoline engine was studied with the software of Excite_TD,by analysing and comparing the performance indexes of the cam profile design methods between polydynamic cam （POL）and individual section acceleration cam （ISAC）.ISAC was chosen to optimize the intake and exhaust cam profile for the variable cycle reciprocating piston engine（VCRPE）in four-stroke or two-stroke mode.In order to validate the rationality of the cam profile design,the multi-body dynamics simulation model of the corresponding valve gear was established and analyzed by SolidWorks.Through comparison of the dynamics simulation results between Excite_TD and SolidWorks,it shows that the results from Excite_TD are consistent with that from SolidWorks, which verifies the accuracy of cam profile optimization as wel .
