Construction of Roller Coaster Bearing Human Body Model and Acceleration Simulation
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.
