An environmental test device and test method for a self-heating device

Abstract

The invention discloses an environmental test device and a test method for a self-heating device. Based on a vibrating slide table, a temperature and static loading test device is integrated and designed, and the synergy of vibration, temperature and static loading is realized. Loading; at the same time, using the design of the vibrating slide table and the pendulum hitting block, since the pendulum hitting block hits the vibrating sliding table table, the moving direction of the vibrating sliding table table is at the same horizontal position as the vibration direction of the vibrating table. The design of stoppers and limit positions realizes the coordinated loading of impact load and vibration load, and finally realizes the comprehensive loading of vibration, temperature, static force, and impact load; the load environment and tests encountered by self-heating devices during use The formulation of the process can standardize the test procedures and operations of the composite environmental tests related to space detector test pieces, and provide technical support for the standardized development and standardized research of related tests.

Description

Technical field [0001] The present invention belongs to the technical field of self-heating device, specifically relates to an environmental test apparatus and test method for self-heating device. Background [0002] Self-heating devices, including space heat sources / power supply devices for deep space exploration such as isotopic heat sources / power supplies, are devices that use radioactive materials to generate heat to provide heat energy / energy for space equipment instruments, and are widely used in various exploration tasks in the deep space environment due to their long life, high reliability, continuous heating and other characteristics. According to statistics, the United States and 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, the lunar exploration mission is t...

[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.
