摘　　要：针对大型游乐设施运行轨迹复杂,载体加速度测量难的问题,基于多自由度集总参数模型法进行仿真,对过山车中人体部位加速度测量进行研究。将人体视为质量、弹簧和阻尼的刚性体,设置模型参数并通过MATLAB和Isight软件进行仿真;构建四自由度垂向人体振动模型,将模拟数据作为激励输入,根据识别参数对人体振动特性分析,得到一定频域内人体振动加速度响应特性;将实测过山车加速度输入人体模型,进行实测数据与仿真结果的对比分析,进一步验证模型准确性。结果表明通过过山车乘载人体模型对特定位置的实测数据进行仿真,以此得到乘客人体部位的加速度动态响应具有合理性,可以为评估游乐设施乘载安全提供依据。In response to solve the problem that the trajectory of large amusement facilities is complicated and the acceleration measurement of the carrier is difficult,a simulation experiment based on the lumped parameter model method of multiple degrees of freedom is carried out to study the acceleration measurement of human body parts in the roller coaster.The human body is regarded as a rigid body with mass,spring and damping,and the model parameters are set and simulated by MATLAB and Isight software.The four-degree-of-freedom vertical human vibration model is constructed,and the human vibration characteristics are analyzed according to the recognition parameters,and the vibration acceleration response characteristics of the human body in a certain frequency domain are obtained.The measured roller coaster acceleration is input into the human body model,and the measured data is compared with the simulation results to further verify the accuracy of the model.The results indicate that simulating the measured data at specific locations using a human body model on a roller coaster ride to obtain the dynamic acceleration response of passengers'body parts is reasonable and can provide a basis for evaluating the safety of amusement rides.
