摘　　要：导水机构是水轮机的主要组成部分,传统的导水机构设计方法过程复杂,需要反复验证,工作量大,效率低。设计过程中没有对导水机构传递效率进行验算和考核,造成某些导水机构参数选择缺乏合理性,导致接力器选取偏大,经济效益低。本文对传动机构进行受力分析,提出优化设计方法,采用工程计算软件Mathcad进行计算,求得既能满足各种约束条件,又具有最优传力效率的传动机构主要参数,以期提高导水机构设计效率和技术经济性。Distributor is one of the main component of a turbine,the process of traditional design method is complex,calling for repeated verification with large workload and low efficiency,and without checking and examination of the transmission efficiency, resulting in lack of rationality in the selection of distributor parameters. In this paper the force analysis of the gate linkage is put forward,and the optimal design method is proposed. The engineering calculation software Mathcad is used to calculate the main parameters of gate linkage which can satisfy the various constraints and the optimal transmission efficiency to enhance the design efficiency and technical economy of the distributor.
