Design and Experiment of High Speed and Mobility Platform for All Terrain

Abstract:
In order to meet the needs of map building, unmanned driving and other advanced technologies, this paper establishes the theoretical mechanical model of high speed and wheeled mobility platform for all terrain under the conditions of flat ground, up and down slope, obstacle crossing, etc., completes the mechanical analysis of the mobile platform, and obtains the theoretical mechanical conditions for the mobile platform to realize the three kinds of motion of flat, up and down slope and obstacle crossing. According to the current requirements of the high speed mobility platform for all terrain, this paper determines the performance parameters of the high speed mobility platform for all terrain, completes the structural design of the gear train, the integrated chassis and the mobility platform as a whole, and carries out finite element simulation analysis on the key parts with large force and torque. Kinematic analysis is also carried out. According to the performance requirements of the platform, the hardware design and electrical system construction are completed. In order to verify the correctness of the theoretical research, this paper made an experimental prototype, and carried out relevant experiments. The experimental results show that the high speed mobility platform for all terrain designed in this paper can achieve high speed operation, has a large load capacity, can complete movements of flat, up and down slope, obstacle crossing, and has strong adaptability for different road conditions.
