Environmental test device and test method for self-heating device

Abstract

The invention discloses an environmental test device and test method for a self-heating device. The device and method take the surface of a vibration sliding table as the basis, achieve the integrateddesign of a temperature and static loading test device, and achieve the cooperative loading of vibration, temperature and static loading loads. Meanwhile, by means of the design of the surface of thevibration sliding table and a pendulum bob striking block, due to the fact that the moving direction of the surface of the vibration sliding table generated when the pendulum bob striking block strikes the surface of the vibration sliding table and the vibration direction of a vibration table are located at the same horizontal position, cooperative loading of an impact load and a vibration load is achieved through the design of a stop block, limiting and the like. Finally, comprehensive loading of vibration, temperature, static force and impact loads can be realized. The formulation of a loadenvironment and a test flow encountered by the self-heating device in the use process can standardize the test steps and operation of related composite environment tests of space detector test pieces, and provides technical support for the normalized development and standardized research of related tests.

Description

technical field [0001] The invention belongs to the technical field of self-heating devices, and in particular relates to an environmental test device and a test method for self-heating devices. Background technique [0002] Self-heating devices, including space heat sources / power devices for deep space exploration such as isotope heat sources / power sources, are devices that use radioactive materials to generate heat to provide heat / energy for space equipment and instruments. Due to their long life, high reliability, and continuous heating And other characteristics are widely used in various detection tasks in deep space environment. According to statistics, the United States, Europe and other countries have used hundreds of space self-heating devices in many space missions, including Pioneer and Voyager, and their service life has exceeded 30 years. [0003] Among the various deep space exploration missions carried out in the past, taking the lunar exploration mission as a...

[0008] 2. The test criteria and methods have not been established, and there is no current relevant standard to guide the test

The current self-heating device comprehensive environmental test task has not yet formed effective test methods, guidelines, and standards have not been established, and cannot guide the development of the test

For example, the determination of the test load loading sequence (different thermal-vibration and vibration-thermal loading sequences have different performance effects on the product), and the evaluation of related tests are still to be carried out.
