Amphibious Unmanned Reconnaissance Vehicle With Hybrid Wheel And Paddle Drive

In order to safeguard China’s territory and sovereignty,we must have the corresponding weapons and equipment to meet the challenges from all sides.In the face of threats from the sea,it is proposed to use small amphibious unmanned reconnaissance vehicles to carry out reconnaissance,intelligence collection and warning missions.In accordance with the requirements and features of the unmanned reconnaissance vehicles,this paper made the following research work:(1)designed a new type of wheel paddle hybrid amphibious unmanned reconnaissance vehicles,the amphibious unmanned reconnaissance vehicles by ship type box frame,body skin,tires and rear wheel blade,round blade slewing mechanism,the three round blade structure,battery,motor,controller,storage and loading,etc.(2)the Adams dynamics simulation software was used to analyze the obstacle jump of the amphibious unmanned reconnaissance vehicle and carry out simulation experiments across the trench,so as to obtain the acceleration,velocity and displacement curves of the amphibious unmanned reconnaissance vehicle under various conditions.(3)the water resistance of the amphibious unmanned reconnaissance vehicle was simulated by Fluent software,and the simulation result was similar to that obtained by theoretical calculation.The impeller is also theoretically calculated by the empirical formula in water,and the impeller is simulated by Fluent software.The thrust values of the impeller are obtained respectively.The simulation results are in good agreement with the results of the empirical formula.(4)complete the stability analysis of small inclination,large inclination and dynamic stability of the amphibious unmanned reconnaissance vehicle,and obtain the curves of high initial stability,static stability and dynamic stability.The results show that the results calculated by the empirical formula are consistent with the software analysis results,and the groundoperation is stable.Theoretically,the design of the amphibious unmanned reconnaissance vehicle is feasible.The relevant conclusions can provide reference for the research in related fields.
