摘要
谐波齿轮啮合刚度计算是其动力学分析的基础。基于有限元加载接触分析原理,结合谐波齿轮的静态及动态接触特点,以单个轮齿啮入-啮出过程中的不同位置为研究对象,选取接触位置离散点,对各离散点的啮合数据进行提取分析,得到了单个轮齿不同啮合位置的单齿刚度曲线及综合啮合刚度曲线。并与已有研究成果进行了对比,验证了该方法的正确性,为研究谐波齿轮传动的动力学特性提供了依据。
The calculation of harmonic gear meshing stiffness is the basis of dynamics analysis. According to the finite element analysis theory of loading contact,and combining with its static and dynamic contact properties,taking each different location during one engaging-in and engaging-out cycle of a tooth as the research object. Then,by extracting the meshing data of discrete point on contact location,the curve of single-tooth stiffness and the synthesizing meshing stiffness in one engaging-in and engaging-out is got. Comparing with the previous researching result,the correctness of the method is verified,which provides the basis for dynamics analysis for harmonic gear.
