| Abstract: | The dynamic model of the bucket wheel stacker is presented in this paper.The kinematic equations and dynamic equations of balance beam are obtained.The dynamic forces in suspending bar and the force acting on the front-support of bucket wheel stacker are calculated.The results agree with the data of the factory.The model can be used to evaluate the operation characters of bucket wheel stacker,and also is used to guide the designing of new bucket wheel stackers. |
