Research On Force Loading Of Dynamic Mechanism Simulating Air Resistance In Missile Magazine

In order to meet the engineering requirements of high speed,high air resistance and high precision in the process of space-craft's bunker separation,a force loading mechanism scheme based on the hybrid control of robot dynamics was proposed in this paper.According to the requirements of the subject,the paper makes an experimental comparison between dynamics and kinematic force loading control principle,analyzes the stability of the dynamic equation,and uses Newton-Euler iterative formula to deduce the single-degree-of-freedom dynamics algorithm,thus simplifying the mathematical model of dynamics.The experimental results show that the dynamic response speed of the dynamic hybrid system adopted within 40ms is about 55.46%higher than that of the traditional kinematic control,and the actual control greatly improves the accuracy and stability of the loading mechanism.Robot dynamics equation of moment of inertia is to determine the important parameters of overall system performance,this article is based on the differential equation of the least squares method to identify the parameters of the second-order under-damped system are identified,in turn,to prove the validity of the algorithm,after in the force loading system of linear programming,for the moment of inertia item are identified,and verify the result of about 40kg*cm~2.For servo motor in the process of high-speed stop and sudden change to the problem,based on the cubic spline interpolation method to design the force curve of load follow,turns servo motor shall be carried out in accordance with the third order curves,using MATLAB to the simulation analysis and writes it to PC software of power load curve to follow,will load strength point and the proposed merger made a smooth and continuous power load curve.
