为了计算某坦克发动机的调速性能，发展了一个柴油机调速系统的模拟模型。将发动机任一工况的调速器齿杆位置与油门开度和发动机转速联系起来，建立了调速器静力学和动力学方程；调速器动力学方程用２个一阶微分方程表示，引入了连续性函数ｓｉｇｍｏｉｄ函数代替非连续性函数ｓｉｇｎ函数，使调速器动力学方程能够方便地应用数值积分方法求解，并且避免了计算结果的小范围振荡。对该坦克发动机调速系统的稳态与动态工况和调速器稳定系数、不均匀度、稳定调速率、瞬时调速率、过渡时间等参数进行了模拟计算，显示这种方法可以用于坦克发动机调速性能的研究。
In order to calculate a tank engine speed performance, the development of a diesel engine speed control system simulation model. The governor gear rod position in any condition of the engine is linked with the throttle opening degree and the engine speed, and the governing equations of the governor and the dynamics are established. The governing equations of the governor are expressed by two first-order differential equations, The continuous function sigmoid function is introduced to replace the discontinuous function sign function, so that the governor dynamic equation can be easily solved by the numerical integral method and the small-scale oscillation of the calculation result can be avoided. The steady-state and dynamic operating conditions of the engine governor system of the tank and the stability coefficient, unevenness, steady speed regulation rate, instantaneous speed regulation rate, transition time and other parameters of the engine speed control system of the tank were simulated and the results show that this method can be used Study on the Governor Performance of Tank Engine.
