摘要
介绍了一种采用电动机进行能量补偿实现惯量模拟的方法,给出了能量补偿的数学模型。通过对飞轮的自由刹车曲线进行回归分析,得出由风阻和轴承磨损等引起的系统损耗模型。在NT11制动器惯性台架上设计了正交试验,得出能量补偿法中几个关键因素(补偿时间、补偿起点、补偿终点和补偿结束条件)的控制规律。讨论了能量补偿法存在的局限性,并给出了解决方案。
A new method using electro motor＇s energy compensation to realize inertia simulation is introduced,and the mathematical model of energy compensation is presented in the paper.The model of system loss model caused by wind resistance and bearing friction is established based on the regression analysis of flywheel＇s free brake curve.Orthogonal experiment on brake dynamometer NT11 are designed to obtain,the control rule of some key factors of energy compensation including time,starting point,ending point and ending condition of compensation.Finally,the limitations as well as corresponding solutions are discussed.
