A vibration isolator zero adjustment method and inspection device

Abstract

The invention provides an isolator zero adjusting-testing method and an isolator zero testing apparatus; by relieving gravity borne by a vibration isolator, force-bearing state of the vibration isolator is kept consistent to on-orbit state, and an included angle between an isolated object and a mounting base is tested; the isolator zero testing apparatus comprises a base; a force sensor fixed at one end to the base and fixedly connected at the other end to a test tabletop; the test tabletop; a self-locking screw fixed to the base; a via hole positioned in the test tabletop; a screw nut having a threaded hole that is vertical; a tabletop accurate test lens bonded to the test tabletop; and an isolated object accurate test lens fixed to the isolated object. Therefore, by using the method and the apparatus, it is possible to simulate the force-bearing state of the vibration isolator after orbit injection and to calculate an adjusting-testing included angle between the isolated object and the mounting base, it is possible to test in the research and development phase whether a mounting angle deviation due to the vibration isolator can meet the design requirements or not, thereby preventing the directional angle deviation of an isolated device from being out of limits after orbit injection.

Description

technical field [0001] The invention belongs to the field of vibration isolation, and relates to a vibration isolator zero position adjustment method and inspection device. By unloading the gravity of the vibration isolator, the stress state of the The angle between the vibration isolator and the mounting base. Background technique [0002] High-resolution remote sensing spacecraft and laser communication technology are more sensitive to spacecraft micro-vibration interference, and the impact of star micro-jitter on imaging quality cannot be ignored, and it has become one of the important factors restricting the performance of remote sensing spacecraft. The jitter amplitude reaches the arc-second level, which cannot be suppressed by the on-board attitude control system (10 arc-second level). The American Hubble space telescope (Hubble space telescope, hereinafter referred to as HST) is caused by the thermal flutter of the solar wing when entering and leaving the shadow of th...
