摘要:
排气门强制开启机构的动态性能直接影响发动机轻载节油配气机构的工作性能和可靠性,在Adams中建立了配气机构多体动力学模型,模拟分析排气门强制开启机构的动态性能.仿真分析表明,排气门强制开启力为518.7 N,与实测值556 N接近,活塞推杆能够在排气门开启最大升程附近顺利进入凹槽强制开启排气门.
Abstract:
The dynamic characteristics of exhaust valve forced opening mechanism affect the engine light loadfuel-efficient valve timing mechanism’s working performance and reliability directly. The paper builds thevalve timing mechanism multi-body kinetics model in Adams,and analyzes the dynamic characteristics of ex-haust valve forced opening mechanism through simulation.The analysis results of simulation show that theforced opening force of exhaust valve is about 518.7 N,which is approximate to the test value 556 N,and thepiston rod can enter into the groove smoothly nearby the maximum opening stroke of exhaust valve and open theexhaust valve forcedly.
