摘要
将动态子结构法应用到光电经纬仪的固有特性分析中,介绍了动态子结构法的原理,依据该原理对光电经纬仪进行子结构划分,建立各子结构的有限元模型,并计算光电经纬仪整机的固有频率。计算结果表明,该方法计算规模小,精度高,具有推广价值和应用前景。
Dynamic substructural is used to analyse the natural characteristic of the electro-optical theodolite, and the theory of dynamic substructual is demonstrated as well. The electro-optical theodolite is divided to body structures based on the theory, the finite element model of every body structures is created, and the natural frequencies is calculated of the electro-optical theodolite. The results show that this method requires less computer memory , has the high precision, a wider range of application and better future than the conventional methods.
