| 摘 要： | 光电经纬仪垂直轴系由于负荷重、转动惯量大,其刚度将直接影响经纬仪的跟踪性能,所以其方位谐振频率显得更为重要,针对这种情况,在与传统的仿真分析软件MSC.patran进行对比的情况下,采用了三维建模软件UG NX4.0自身集成的建模仿真一体化功能对经纬仪垂直轴系进行了模态分析,得到了垂直轴系前三阶固有频率及振型,仿真结果满足实际工作需要,并且找到了刚度薄弱环节,能够指导以后的优化设计工作.并通过实验实测方位转动谐振频率,与仿真分析结果进行比对,验证了仿真分析方法的可行性.

| Abstract: | Because of heave load and big moment of inertia,the stiffness will directly affect theodolite's tracking capability,so its azimuth resonance frequency becomes more important.In this situation,the paper makes modal analysis for theodolite's vertical axis using three-dimensional modeling software UG NX 4.0 after contrasting with the traditional analysis software MSC patran,and gets its first three-order azimuth resonance frequency and mode shape,and the simulation result satisfies the needs of work.Also the p... |
