摘要
利用N次谐波法对配气凸轮型线进行拟合,分析拟合结果,指出使用N次谐波法时的一些问题及其原因。结果表明,N次谐波法是进行凸轮配气机构性能分析的一种简洁有效的方法,为配气机构的运动学和动力学计算提供了有力的支持。
The valve cam profile was fitted by using Nth-degree harmonic method, and the results were analyzed. Some problems existed in using Nth--degree harmonic method were pointed out, and the reasons for the problems were analyzed. The Nth-degree harmonic method is an effective and simple method, and it is universal to adapt for analyzing the behavior of valve gear, kinematics and dynamic characters can be calculated.
