Title Design and Analyse of a system to automatically pick up the propellant charge modules
Abstract
A system to automatically pick up the propellant charge modules is one of the key techniques of artillery’s fully automatic feeding system.This paper put forward several kinds of design of automatically pick up system which included in automatic feeding system and finished the final design.By using the virtual prototype software,the kinematic and dynamic simulation of the mechanism is carried out and the movement and the force of the key parts are analyzed.The date is provided for the engineering prototype.The main work is as follows:
Discuss of the automatically pick up system: By comparing the artillery which is on active service or under developing,we discussed the arrange of the automatically pick up system and designed the core components.Cmparing the characteristics of the design schemes,we put forward three kinds of overall design scheme of the system to discuss.
Design of the automatically pick up system:we finished the finish the final design..Then the 3-d model of the manipulator was established by ProE.
Dynamic analysis of the automatically pick up system:The virtual prototype model was established to simulate and analyze the force and torque in each joint by using the virtual prototyping software.we analysed the stress,velocity and acceleration changes in the process of work cycle to verify the correctness of the system continuous driving scheme.
