Chapter 3 analyzes the parameters of the dynamic equations, such as the motion mass, the deflection curve length of the belt, the main resistances coefficient and the belt's modulus of elasticity.

在第三章中对输送机系统动力学方程中的各影响参数：参与运动的质量、输送带挠曲线的长度、主要阻力系数和输送带的弹性模量进行了分析。

The results are the following: When calculating the motion mass, it is better to use idler's equivalent mass instead of the rotating part mass and serial idler's rotating inertias and equivalent mass are calculated. The accurate analysis result for the deflection curve length of the belt shows: The error calculated by the approximate parabola length is lower than 10〓. Thus the approximate method is accurate enough for calculation. The relations between the running resistances coefficient and the belt velocity are studied by experiment, which are the bases for calculating the linear coefficient values between them.
