Analysis Of Dangerous Ammunition Handling Robots

Dangerous ammunition handling robot can adapt well to the changes of ground shape with a good stability.which has the ability to through all kinds of typical obstacles,completes tasks in the complex environmental conditions.The further research of dangerous ammunition handling robot is along with the developments of multi-body dynamics theory and vehicles-the ground theory.Modern computer-aided methods have allowed large and complex systems to be modeled and simulated accurately and efficiently.All of these offered a powerful technology and theoretical support for the ride comfort analysis of dangerous ammunition handling robot and the analysis of the limit working ability.The High-speed maneuverability of tracked vehicle relates to engine power and transmission efficiency,but if we want to increase the average speed of vehicles and improve the trafficability characteristic,it depends on the performance of the traveling system.The traveling system of tracked vehicle consists of tracked propulsion system and suspension system.Combined with the design requirements,by analyzing the force of the traveling system,the author creatively designed air spring and torsion bar spring in parallel as the elastic element of balanced suspension,and designed the overall approach of traveling system on this basis.In this paper,based on the virtual prototype technology,using three-dimensional modeling software UG and multi-body dynamics software RecurDyn,digital model of the dangerous ammunition handling robot was established.By analyzing the contact relation between the crawler and the ground,and the influence of soil parameters on the driving performance,established the simulate road.Based on the simulation of the model running on the flat surface and C level road in different speed,analyzed the influencing factors of dangerous ammunition handling robot riding comfort.According to the results of spring optimizated,simulated climbing stability under different speed during load running.Changing the shape of road tested the passing ability of robot.Through optimization design,has get the optimal parameter of traveling system.
