摘要
垂直轴系是经纬仪的基础和主要承载部件,它的强度、刚度和固有频率直接影响着经纬仪的精度、稳定性和跟踪性能。传统的经纬仪结构设计一般是在保刚度的前提下,参照以往相似类型进行经验设计,这种设计往往不是最佳设计,都有改进、优化的余地。针对这种情况,对经纬仪垂直轴系进行建模和有限元分析,得到了垂直轴系的位移、应力和固有频率。基于轻量化的考虑,对垂直轴系的主要承载件转台和垂直轴进行了优化设计,在满足刚度等要求的前提下,减轻了垂直轴系的重量。
The vertical shaft is the basis and the main bearing oomponents of theodolite, and its strength, stiffness and natural frequency of a direct impact on the accuracy of theodolite, stability and tracking performance.Structural design of the traditional theodolite is generally under the premise of stiffness in Bulgaria,taking into account the past experience of similar type design, which is often not the beat design, there are improvements,optimized room.In view of this situation,the vertical shaft of the theodolite modeling and finite element analysis, has been the vortical shaft of the displacement,stress and natural frequency. Considorations based on lightweight, vertical shark carrying pieces of the easing are also the main base of the turntable and the optimized design, to meet file stiffness requirements under the premise of reducing the weight of the vertical shaft.
