Research On Vacuum Resin Dosing Technology Applying In Electronic Body And Special Material Of Air-To-Air Missile

The development of Hi-Tech industry attract our notice on its more and more important function on National defence industry, and air-to-air missile is a kind of equipment of National defence. Electronic body and deflecting coil are indispensable parts in air-to-air missile. In order to keep their high performance for a long time, we had to deal them with cast resin. This thesis undertakes the technology research of cast resin connecting with fact item.As technical difficulty, the author makes experiment and undertakes research on the technology of dosing electronic body detailed. Based on viscous hydrodynamics, the author simulates simply the flow filed inside electronic body by ANSYS, and then uses ultrasonic high frequency vibration equipment to improve its fluidness. Thus we can carry out effectively control to cast resin.In the technology of dosing deflecting coil, special material as solid reagent of resin is one kind of intensional caustic reagent. Author does some design on tube union and ball valve aiming at that. Vacuum level directly influences on the quality of cast resin, so author makes some design on vacuum static seal in this thesis.High viscosity E-51 resin and special material are both sensitive totemperature, and the good fluidity of potting compound is guaranteed in suitable temperature. The author adopts intelligence PID control strategy in the basis of FXhPLC that programmed combining general PID with production rules of expert system, then the system can be completed precise temperature control.
