The Design And Analysis Of Drop Impact About A Miniature Throwing Scout Robot

At present,micro-reconnaissance robot system research is booming,dangerous environment Micro-reconnaissance robots generally require small size,light weight,can be easily carried into the reconnaissance site,and can be ready in a short time and put into work.With the progress of technology and the diversification of tasks,the research on micro-throwing reconnaiss ance robot system with strong function has become a new research hotspot.In this paper,the laboratory purchased T he Recon Scout IR robot as the basis for research.Scout robot research,observation and found its shortcomings,while making improvements.T hrough the analysis,the use of Pro / Engineer to establish micro-throwing detection robot three-dimensional solid model.In the design process,completed the installation of the internal module layout,the installation of the motor design,switch design,quick change structure design,impact structure design.The design of the quick change structure is innovative and can realize the characteristics of the robot changing the wheel type without any use of the tool according to the use environment.Through the three-dimensional solid model,the collision mechanism of the throwing detection robot from the height is analyzed,and the structure of the robot and the overall force are explored,and the safe drop height is obtained by the simulation experiment.Numerical method is used to calculate the energy method of multi-body continuous collision dynamics model to solve the impact problem.According to the design parameters of the robot,ANSYS / LS-DYNA is used to simulate the robot.T he simulation results show that the robot has different drop height and the size of the impact force of each component under different attitude,and the strength of the robot as well as the dangerous part is analyzed.It is convenient,reliable and convenient for the quick-change structure of this throwing robot.T he contents should be optimized for the rubber parts of the wheel,the axle,the axle and the hub contact;the maximum allowable drop height is about 5 meters.The virtual prototype model simulation experiment method to optimize the robot structure design,can reduce the risk of failure of physical experiments,greatly accelerating the design speed.This paper successfully through the analysis,simulation of the data,the successful design of a miniature throwing invest igation robot.And this throwing robot quick change structure is convenient,reliable and convenient;physical prototype through the good,able to withstand 5m down the impact.
