摘要
卸船机在抓斗和物料提升时,抓斗及物料所产生动载通过钢丝绳传递到卸船机前大梁上,从而对前大梁产生冲击,造成前大梁的振动。通过Ansys分析软件模拟这一过程,得到冲击后大梁的振动曲线,得到了大梁的振动幅值及振动频率等结果。
When ship unloader hoists grab and cargo,dynamic load will transmit to frame leg through wirerope,then frame leg will vibrates by load shock. In this paper,this process is simulated by Ansys,then the vibration curve of frame leg caused dynamic load is obtained. Finally,the amplitude and frequency of frame leg are shown.
