基于液体工作环境和客户需求确定的目标参数，对电动执行机构进行结构设计，比照参数指标要求确定了丝杆、减速机构、电机的关键参数。采用动、静组合的密封方式，并与铜衬套配合，提高了电动执行机构的密封可靠性。利用有限元分析软件对推杆和壳体进行力学仿真，通过对应力及变形结果分析，得出结构强度满足要求。
Based on the liquid working environment and target parameters determined by customer needs, the structure of the electric actuator is designed. The key parameters of screw, reducer and motor are determined according to the requirements of parameter indexes. The reliability of sealing of electric actuator is improved by the combination of dynamic and static sealing and the coordination with copper bushing. The finite element analysis software is used to simulate the push rod and the shell. Through the analysis of the stress and deformation results, the structural strength meets the requirements.
