Research On Motion Simulation And Kinetic Analysis For The Missile-borne Mechanism

When the bullet is shot out, the fuze and control equipment which are inthe bullets will fly with the bullets in the air. The fuses and control equipmentsis under tremendous acceleration and load in the complex environment where thesethings are easily damaged so that the bullets can’t complete the task of hittingthe enemies. If the bullet occurred early burst, it may cause some damage toown person. So it is very important to understand and master the motioncharacteristics of these fuze and control equipment during the flight andguaranteeing the normal operation during the flight is a particularly importantthing. The motion simulation device of missile-borne mechanism is a groundsimulator which can be used to missile-borne mechanism’s movement in the air.It is simple and have good repeatability, which’s law of motion can be controlled.The motion simulation device provided the conditions for developing the fuze andcontrol system. There is a large centrifugal force during the actual testingprocess of the simulation device, which will have a great impact on the entiredevice, and it may lead to the instability of the whole system’s running,affecting the fidelity of the simulation test and the accuracy of the data. Theserious situation is that it may affect the movement of the two motors used tosynthesis the two movements about nutation and precession so that the two motorsmay be broken. This is a major existing problem during movement of the simulationdevice.The paper primarily presents and generalizes the movement principle and basic theories relating to the bullet and rocket and then carries out theoreticalanalysis on the movement principle and motion equation of bullet so as to obtainPrinciple diagram of missile-borne mechanism simulator.building the mode thesolid mode of The motion simulation device by 3D modeling software. Then，optimizing the entity model by using mechanical simulation software ADAMS inorder to establish the dynamic mode and make the device’s motion simulationdevice on the computer. do the kinematic analysis of the the simulation deviceanalyze the force of spindles connected to the main two motors finally bypost-processing module of the simulation software after validating the dynamicmodel. Thus combining these data to choose the reasonable fast and slow motors，adding deceleration devices. So, achieving this purpose of this thesis that usingof computer simulation technology to a reasonable choice of motor and optimizethe structure of the simulation device. Providing a quick and accurate way forresearch on motion simulation’s structure of missile-borne mechanism and reducethe cost of the device design, manufacturing and test.
