DYNAMIC MODELING AND ANALYSIS OF LARGE-SCALE ROTARY KILN WITH MULTI-SUPPORTING
大型多支承回转窑动力学建模与分析

Rotary kiln is a key equipment in the production of metals,cement and refractory materials.For studying bending vibration of its body system related with its axis movement,the method of transfer matrix is developed to set up the body system's dynamical model with the anisotropy equivalent stiffness equation of the wheel-bearing system.An example is given to illustrate why there are dynamical errors in the common axis measurement methods.The transfer matrix model provides a basic equation for computing dynamical stresses of roller and dynamical errors in the axis measurement.
