摘　　要：针对游乐设施的运行形式千变万化、加速度难以精确计算、物理样机测试成本高的问题,在力学分析的基础上,提出游乐设施加速度的本质是惯性加速度,通过惯性力求解游乐设施加速度的方法。以滑行车类游乐设施自旋滑车为研究对象,对自旋滑车进行刚体动力学仿真,获取自旋滑车在整个运行周期内各向加速度的时间历程曲线,依据相关规范对加速度进行分区,并对束缚装置进行选型。计算结果表明,自旋滑车设计加速度的区域为区域2,束缚装置满足设计要求。In view of the complex and changeable operation of amusement facilities,it is difficult to calculate the acceleration accurately,and the cost of prototype test is high.On the basis of mechanical analysis,the essence of amusement facilities acceleration is inertial acceleration.Therefore,a method is proposed to solve amusement facilities acceleration by inertial force.Taking the self-revolving pulley as the research object,simulation analysis of rigid body dynamics is carried out under the operating conditions,and the time history curve of the acceleration in each direction during the operation is obtained.According to the relevant specifications,the acceleration is partitioned and the restraint device is selected.The calculation results show that acceleration area of the self-revolving pulley is zone 2,and the restraint device meets the design requirements.
