Abstract

The invention discloses a measuring device and system for a simulated weight loss unloading force of a spacecraft antenna, and belongs to the field of unloading force measurement. The measuring devicecomprises a pressure sensor, an elastic element, a soleplate and a pressure measuring and displaying instrument, the lower end of the pressure sensor is connected to the elastic element, and the elastic element is arranged on the soleplate; and the pressure sensor is also connected to the pressure measuring and displaying instrument. When a tested piece presses the sensor, the elastic element canbuffer a pressure on the sensor, and the extreme value of the unloading force is reduced; and deformation of the tested piece can be prevented during measurement, and the spacecraft antenna is protected.

Description

technical field [0001] The invention belongs to the field of unloading force measurement, in particular to a space vehicle antenna simulated weightless unloading force measurement device and a measurement system thereof. Background technique [0002] During the in-orbit working phase of the spacecraft antenna, under the action of space thermal load, the reflector surface will produce a corresponding deformation, that is, thermal deformation, and thermal deformation is one of the important factors affecting the radio frequency performance of the antenna, especially for antennas that are more sensitive to thermal deformation Even more so. In order to accurately evaluate the influence of the reflector's on-orbit thermal deformation on the antenna's RF performance, it is necessary to conduct a thermal deformation test on the reflector, and then take corresponding measures to reduce the risk of the antenna's on-orbit RF performance deterioration due to thermal deformation.
