The research on surface stability of the forming of high precision for large and high precision reflecting panel

Aiming at the character of large size and high precision reflector panel, taking the forming technique of high precision reflector panel which is based on the principle of " discrete nails die, honeycomb sandwich, vacuating press ", based on structure parameter test and stiffness test, ensuring sandwich panel structure which satisfy large scale and high precision reflector panel; based on the method of numerical simulation, ensuring the changing rule of surface precision which is in working state under the effect of gravity and environment temperature, providing a basis on ensuring the using condition for high precision reflector panel.
