摘要
大摆锤是一种大型的游乐设施,乘客乘坐在固接于转盘上的座椅上,经历着摆动加旋转的合成运动,由于大摆锤运行速度高、加速度大、载荷工况复杂,有必要在不同工况条件下对大摆锤的动力学参数进行分析。利用ANSYS Workbench的刚体动力学模块Rigid Dynamics,对大摆锤进行动力学仿真分析研究。分别在满载和偏载的虚拟环境中,模拟大摆锤整体的运动及受力情况,通过仿真分析,在设计阶段就可获得大摆锤在不同工况下运行时各部件的速度、加速度及载荷时间历程,提高了设计效率和计算精度,为大摆锤的设计提供了参考。
Big pendulum is a type of large-scale amusement equipment; passengers sit on the seats fixed to turntable and experience the synthesis movement of swing and rotating. Due to the high speed, large acceleration and complex loading conditions of the large pendulum, it is necessary to analyze the kinetic parameters of the big pendulum under different working conditions. The Rigid Dynamics module of ANSYS Workbench is used to conduct the dynamic simulation analysis and research for the big pendulum. In the virtual environment of full-load and part-load, the motion and force condition of the entire big pendulum are simulated. Through the simulation analysis, the velocity, acceleration and loading time of each component under different operating conditions can be obtained at the designing stage. This method improves design efficiency and computational accuracy. The conclusion of this paper puts forward the reasonable suggestions for designing the big pendulum.
