A conveyor belt driven by wound rotor motors produces dynamic tension, velocity and acceleration during starting. The terrible situation (such as resonance) in dynamic analysis and design is that system natural frequencies are equal to those for switching off electric resistances. This paper analyzes and determihnes system natural frequencies based on a modeling method of receptances with the analysis of sub-systems model and of the principle of their addition and conveyor loop closure. It also puts forward to calculate the time interval for switching off electric resistances. The starting of one conveyor is simulated by lumped-mass-spring-model software to further illustrate the influence of time interval for switching off electric resistances on conveyor dynamic behavior. Two methods are also compared. The receptance model is proved to be an excellent alternative. 相似文献
