Research on Dynamic Characteristics of Vibration Shakeout Machine Based on Finite Element Analysis
The sand casting industry usually uses vibration shakeout machine to vibrate the sand,and drives the positive and negative rotation of the eccentric cam by the motor to drive the vibration screen to stimulate the vibration,so as to achieve the purpose of repeated recycling of the shakeout and reduce the consumption of raw materials.Aiming at a certain type of shakeout machine,a 3D simulation model is established.Through modal and harmonic response analysis,the optimal exciting frequency of the vibrating shakeout machine is obtained.In addition,through vibration system simulation,the influence of different exciting force,elastic coefficient and cam rotation speed parameters on shakeout machine vibration is analyzed,which has important reference significance for the selection of shakeout machine parameters.
