大型磨矿机软起动过程中的动载荷分析

Analysis on the Dynamic Load Produced in Smoothly Starting of a Large Mill

通过建立磨矿机起动过程弹性动力模型，分析了大型磨矿机软起动装置的结合时间及方式对起动动载荷的影响，给出了相应的计算公式并采用Ｍａｔｌａｂ绘出了相关的特性曲线。

By making a elastic dynamic model of a large mill in its starting, the paper analyzes the effect of smoothly starting time and accelerating pattern on the dynamic load of the mill produced in its smoothly starting, gives some correspounding calculation formulae, and draws the relative charac terstic curve by use of the Matlab.
