【摘要】 偏心轴作为对辊式振动破碎机的核心部件，其受力情况直接影响设备的工作性能。采用EDEM、ANSYS Workbench和n Code软件搭建单向耦合通道，对破碎机破碎过程进行仿真，并对偏心轴进行受力分析，预测偏心轴的疲劳寿命。仿真结果表明，偏心轴最大应力值为127.8 MPa，安全系数为2.78，疲劳寿命为8.377×10¹¹次，满足设备的使用要求，为破碎机的制造生产提供了参考。更多还原

【Abstract】 The eccentric shaft was the core component of the roller vibration crusher,and its stress directly affected the working performance of the equipment.EDEM,ANSYS Workbench and nCode software were used to build a one-way coupling channel to simulate the crushing process of the crusher,and the stress analysis of the eccentric shaft was carried out to predict the fatigue life of the eccentric shaft.The simulation results showed that the maximum stress value of the eccentric shaft was 127.8 MPa,the safety factor was 2.78,and the fatigue life was 8.377×10¹¹ times,which met the requirements of the equipment and provided a reference for the manufacture and production of the crusher.更多还原
