Modelling and Simulation of Smoothness in a Man-on-wheels Assisted Marching Device

The man-on-wheels assisted marching device is a mobile device that enhances the rapid marching. capability of a single soldier. The vibration characteristics of the device not only affect the comfort and fatigue of the soldier, but also affect the travelling safety of the device. This paper establishes the man-machine dynamics model and the eight-degree-of-freedom vibration model of the soldier wheeled assisted marching device, and applies MATLAB to design a vibration simulation system to simulate and calculate the vibration characteristics of the soldier wheeled assisted marching device. By calculating its acceleration rms and weighted vibration level, the result of human subjective feeling is obtained, which proves that the device has good smoothness.
