一种确定发动机转动惯量的新方法

One New Method to Estimate the Inertia Moment of an Engine

讨论了当前一些确定转动惯量的方法,提出了一种新的发动机转动惯量确定方法———加速惰转法。试验结果表明,该方法误差在2%以内;并据实测结果对影响该方法精度的因素进行了讨论,提出了改进措施。

Some current methods for determining the inertia moment of moving parts of engine are discussed and one new method-accelerating-decelerating method is proposed. Eexperimental results indicate that its accuracy is within 2 %. Based on calculating and experimental results, the factors that influence measurement accuracy of the method are discussed and some improvements are proposed.
