The following work has been done in this paper : the load characteristic and design calculation method of spring are systematically studied . the method of using assembled springs to simulate flexible joint is presented , and then the structural configuration of simulation joint is given . the method above - developed can be used to calculate the parameters of the simulation joint on the given load and displacement conditions 主要内容包括以下几个方面：从弹簧的受力特性出发，系统地研究了弹簧的受力及设计计算方法；通过受力特性分析，提出了采用弹簧组合的形式来模拟柔性接头的设计方法，并给出了模拟接头的设计形式；结合理论方法，开发了能够用于给定载荷和位移条件下计算所需模拟接头参数的应用软件，并给出了模拟接头参数设计的算例。
The main function of a governor is to monitor the speed deviation of a hydro turbine unit and convert it into the displacement deviation of the servomotor according to a specific characterisic . it is used to control the opening of the guide apparatus and to ensure the unit run steadily at fixed speed under a given load 调速器的主要功用是检测机组转速偏差，并将它按一定特性转换成接力器的行程偏差，借以调整机组导水结构的开度，使机组在给定的负荷下以给定的转速稳定运行。
