Solid Rocket Motor Mandrel Spraying Equipment Design And Motion Simulation Analysis

The solid rocket motor is major power equipment in aerospace engineering, therefore, the development of safe and reliable rocket engine production equipment is an important issue in the field of mechanical engineering.Quality of housing is the main rocket engine parts negative mass, so engine housing choose compound material. The quality of the mandrel forming greatly affected the composite wrapping, curing, releasing. This article design a new easy removal, low cost solution for molding equipment.We ensure the overall scheme of spraying equipment for functional requirements of mandrel spraying equipment, analyzed the composition of the core mold equipment system. Design structural of mandrel rotation system and the plaster coating system. Ensure the motor model and Strength calculation of the central axis of the mandrelApply UG software to complete virtual assembly and motion simulation of mandrel spraying equipment. Use motion module of UG software creates motion simulation program of mandrel spraying equipment systems and analyzed it. Motion Simulation results are easily obtained mandrel spraying equipment systems kinematics and plot speed-displacement curve, simplifying the process of motion analysis. Use UG motion simulation module can obtain the motion characteristics and avoiding abstract a large number of theoretical derivation, thus greatly improving the efficiency and accuracy of the motion analysis.Due to the large size of the mandrel, there are certain requirements for the mandrel center axis length. So checked and load analysis for the strength of the central axis of the mandrel. Using ABAQUS finite element analysis software do static analysis on the central axis of the mandrel, it is possible for the central axis of the mandrel in the mandrel during rotation of the forces and deformation accurately obtained, which proves mandrel central axis of the deformation range whether in their affordable range.
