摘　　要：针对某沥青搅拌设备振动筛筛箱横向摆动过大的问题,根据振动筛的结构特点,首先在ANSYS中对减振弹簧进行仿真分析,找出筛箱横向摆动过大的原因,然后提出改进方案,最后通过试验验证方案的合理性。结果表明,振动筛减振弹簧的结构特性对筛箱横向摆动的影响很大,合理调整减振弹簧的固有频率可以有效地抑制筛箱横向摆动。Aiming at the problem of the screen box's big lateral oscillation of asphalt mixing equipment,firstly this paper finds the cause of the screen box's big lateral oscillation according to the structural features of vibrating screen by the simulation analysis of damping spring in ANSYS,then the improved scheme is put forward,and finally the rationality of the scheme is verified by the experiment.The result shows that the structural properties of damping spring have great influence on the screen box's lateral oscillation which can be effectively reduced by the appropriate adjustment of damping spring's natural frequency.
