Abstract

The invention discloses a high-precision dynamically controllable temperature simulation device. The temperature simulation device is used for controlling the temperature of the spacecraft load; the temperature simulation device comprises vacuum cold black environment simulation equipment, a low-temperature platform, a radiation boundary temperature control structure and a conduction boundary temperature control structure. The conduction boundary temperature control structure is arranged on the low-temperature platform; the spacecraft load is arranged on the conduction boundary temperature control structure, the radiation boundary temperature control structure covers the spacecraft load, the radiation boundary temperature control structure and the conduction boundary temperature control structure cooperate to control the temperature of the spacecraft load, the temperature control modes are diversified, the temperature control range is large, and the temperature control precision is high. The radiation boundary temperature control structure and the conduction boundary temperature control structure are not in contact with each other and do not influence each other, so that the control logic is more convenient.

Description

technical field [0001] The invention generally relates to the technical field of spacecraft load ground testing, in particular to a high-precision dynamic controllable temperature simulation device. Background technique [0002] For the temperature-sensitive components of conventional spacecraft loads, in order to ensure its normal use, the requirement for its thermal control system is generally that the temperature fluctuation is not higher than ±0.5°C. [0003] With the continuous deepening of deep space exploration missions, the scientific instruments used as payloads to carry out detection missions are becoming more and more sophisticated. The optical measurement elements, the core components of new space telescopes and space gravitational wave detectors, have put forward ultra-high precision requirements for the temperature environment. [0004] In order to verify the influence of temperature environment changes on the performance of sensitive components inside the load...
