基于UG平台,以行星轮爬壁机构为研究对象,根据设计要求完成了其所有零部件的结构设计、三维建模及虚拟装配;应用ADAM S对其进行运动仿真,得到位移—时间、角速度—时间的关系曲线,为行星轮爬壁机构的动力学分析提供了科学依据;应用AN SY S软件进行了有限元模态分析,得到了前6阶模态和振型图,使机构的固有频率避开了共振频率,减小了机构的振动。
Based on the UG platform, taking the planetary wheel climbing wall mechanism as the research object, the structural design, 3D modeling and virtual assembly of all its components are completed according to the design requirements. The motion is simulated by ADAMS and the displacement-time and angular velocity- Time curve provides a scientific basis for the dynamic analysis of planetary wheel climbing wall mechanism; finite element modal analysis ANSYS software was used to obtain the first six modes and mode shapes, the natural frequency of the mechanism Avoid the resonance frequency and reduce the vibration of the mechanism.
