| 摘 要： | 对一个有直动液压间隙调节器（ＨＬＡ）的气门机构进行了试验和动力学计算分析。实测了ＨＬＡ泄沉特性以确定ＨＬＡ模型中模拟泄漏的阻尼参数。为了获得气门机构的实测运动规律以验证计算结构和估算ＨＬＡ高压腔混气量，对该机构的气门加速度和ＨＬＡ高度变化量进行了动态测试。动力学计算结果和实测结果对比表明所建立的两种气门机构动力学计算模型都是可用的。分析计算结果对模型参数的敏感度。

| Abstract: | Experiment and dynamic analysis of a valve train with hydraulic lash adjuster (HLA) were reported. Leakdown test of the HLA was conducted to determine the damping factor in the HLA spring - damper model. On a test rig, the valve accelerator and the shortening of HLA were measured to examine the two dynamic models of valve train and to estimate the air content in the HLA high-pressure chamber. The two models of valve train were validated by the comparison between simulated and measured results and the sensitivity of simulated valve tra in dynamics to model parameters was also analyzed. |
