Influence of the screw structural parameters on the vehicle driving performance
In order to optimize the structural design of the propeller vehicle,the vehicle driving process was simulated based on Multi-Body Dynamics(MBD)and Discrete Element Method(DEM),and the influence of the screw parameters on the vehicle driving performance was studied by changing the screw parameters,including the helix angle and the number of helix.The simulation results showed that under different driving speeds and rotational speeds,the vehicle had better driving conditions and driving performance when the helix angle was 30°;when the number of helices increased from 1 to 2,the slip rate was significantly reduced,the yaw angle was reduced and the driving process was smoother.The research results can provide reference for further research on propeller vehicles.
