Application of Kinetic Simulation in Design for Impact-crusherWANG Qing,ZHANG Yi-du,ZHANG Hai,ZHANG Hong-wei(School of Mechanical Engineering & Automation,Beihang University,Beijing 100083,China)By taking advantages of the technology of CAD and simulation,a virtual design environment for the impact-crusher was established in computer.In the design process for the impact-crusher,the three-dimensional geometrical models and finite-element models of the parts were set up and the performances of the parts were analyzed by kinetic simulation.With the results of simulation,the design could be optimized,the period of development could be shortened and the cost could be lowered.kinetic simulation;impact-crusher;finite-element
