Abstract

The invention discloses a high-precision special measuring and adjusting detection method for a solar heat collection window of a spacecraft, and the method comprises the following steps: S1, carrying out positioning of a special tool for measurement: carrying out zero calibration of a depth gauge through a high-precision plane, and carrying out calibration on a process plate for the installation of the heat collection window; S2, performing preliminary installation of steel wires of the semi-rigid membrane support structure: completing installation of the membrane support structure according to the requirements of the model, and ensuring that the intersection position of the two steel wires is parallel to the upper surface of the top plate; and S3, performing semi-rigid membrane support transverse and longitudinal steel wire measurement: determining the highest position of the transverse and longitudinal steel wires by means of a one-dimensional guide rail, measuring the highest position, locking the depth gauge, determining the height through three times of measurement, and recording the marking position and measurement data. According to the invention, the stability of the measuring tool is high, the top plate of the Mars rover is used as a direct reference during measurement, the reliable fixation of the measuring tool is realized, the measurement error caused by manual operation in the measurement process is avoided, and the stability of a test system is improved.

Description

technical field [0001] The invention relates to the technical field of detector detection, in particular to a high-precision special measurement and adjustment detection method for a solar thermal window of a spacecraft. Background technique [0002] When my country's first "Zhurong" Mars rover conducts scientific exploration on the surface of Mars, it will face the harsh low-temperature environment at night on Mars. Solar collectors are installed on the roof of the Mars rover to achieve a fire-day period during the scientific exploration stage on the surface of Mars. , through the heat-absorbing coating of the heat-absorbing plate, the solar energy penetrating through the heat-collecting window is efficiently collected, and the Martian wind and Martian dust are isolated from the internal equipment of the Mars rover through optical components. [0003] The rover heat collector consists of two parts: solar heat collecting windows and solar heat absorbing panels. The core func...

Problems solved by technology

There are strict precision assembly requirements between the membrane installation structure and the membrane support structure to ensure that the frame of the heat-collecting window can expand and contract in the radial direction synchronously with the rise and fall of temperature, and any operation must not block its synchronous expansion and expansion, and the measurement and adjustment will occur Deviations may cause damage to the covering film. How to adapt to the ultra-low temperature environment The precision measurement and adjustment of the thermal collector window of the Mars rover is a key and complex measurement problem
