Scenario simulation test device and test method for self-heating device thermal shock into water accident

Abstract

The invention discloses a thermal shock water entry accident scene simulation test device and a test method of a self-heating device, which can complete thermal shock test, thermal shock water entry test, seawater simulation test, environmental adaptability assessment test of long-term storage state on the seabed and seabed vibration environment adaptation Various test types such as performance assessment test, the above test types can comprehensively simulate various accident environmental loads of self-heating devices in launch and crash scenarios, and can be used for self-heating devices from dynamic scenarios to deep-sea storage scenarios. It provides analysis tools for the product status response of the product, and provides technical support for the product's accident environment adaptability assessment, improvement design, etc. The test piece launching device of this application simulates the scene simulation of the test piece falling into the seawater, and can simulate the test piece falling into the water. Compared with the traditional technology, the scene simulation is more realistic and the details are more abundant.

Description

technical field [0001] The invention belongs to the technical field of self-heating devices, and in particular relates to a simulation test device and a test method for a thermal shock water entry accident scene of a self-heating device. Background technique [0002] Self-heating devices, including space heat sources / power sources for deep space exploration such as isotope heat sources / power sources, are important in the field of space development due to their compact structure, high reliability, good radiation resistance, high mass specific energy, and low failure rate. The United States and the Soviet Union / Russia have repeatedly used self-heating devices for space missions. However, the use of radioactive materials in self-heating devices presents safety risks in unexpected events. [0003] Accidents have the following characteristics: [0004] 1. In the event of an accident, the product will fall at a certain height at a certain speed; [0005] 2. When falling into th...

AI Technical Summary

Problems solved by technology

[0006] 3. The product is a self-heating product, which is greatly different from seawater temperature, forming a temperature shock;

[0008] 5. If the product is difficult to salvage, it will be located on the seabed for a long time

[0015] 2. The load analysis of the thermal shock water entry accident scene is not in-depth

[0017] 3. The existing test process is not standardized

[0018] The current thermal shock water test carried out in various countries has not formed a unified standard, and there are no relevant standards, so it is impossible to standardize, guide and carry out the test

[0019] In general, since the application field of self-heating devices is at the forefront of science and technology, the analysis of product safety accidents in various countries, especially the research on the scene of thermal shock into water accidents is still in its infancy
