摘要
为了减少反击式破碎机锤板的材料用量,用MSC.Dytran对某型号反击式破碎机转子与矿石的碰撞过程进行了动力学仿真。对碰撞过程中锤板的强度与刚度进行了分析,利用仿真结果对锤板进行了结构优化。优化后在满足材料强度条件基础上有效减少了锤板材料用量。结果表明:MSC.Dytran可以较好地对反击式破碎机转子与矿石的碰撞过程进行动态仿真,对反击式破碎机的合理化与轻量化设计有重要意义。
In order to reduce the dosage of materials for hammers, the collision that the hammers of an impact-crusher collide with the ore has been simulated by MSC.Dytran. Stress and deformation of hammers in the process of collision are analyzed. Taking advantage of the results, the dimension of hammers has been optimized. Satisfied with the condition of intensity, the dosage of materials for hammers is reduced. It indicates that MSC.Dytran can be preferably used to simulate the hammers＇ colliding with the ore and it could be important for rational and lightweight design.
