Abstract:
Objective Modern warfare is geographically complex and changeable.The lack of terrain adaptability restricts the popularization and application of rescue robots in the frontline war.To solve this problem,this paper designs a new longitudinal-arm suspension mechanism,and carries out principle analysis and simulation optimization.Methods The automatic dynamic analysis of the mechanical system(ADAMS)was used to establish the virtual suspension model. According to the condition of rescue robot parameters, appropriate constraints and objective functions were set up to optimize the length of the suspension rod and spring stiffness coefficient.Results The suspension structure parameters were optimized by experimental simulation.The single longitudinal-arm suspension could convert the small stroke of the helical spring shock absorber into the large stroke of the tire movement according to the comparison of the experimental data. Conclusion The research and design of single longitudinal-arm suspension are of great significance to develop its physical prototype and to select the helical spring shock absorber,playing an important role in promoting the development of the small wheeled rescue robot.
