The invention involves a comprehensive test system that stacked the temperature environment, mechanics environment and the gas source environment, including an environmental simulation compartment. The environmental simulation compartment has an independent gas source division system, temperature division system and vibration system.The gas source division system, temperature segmentation system and vibration system are connected to the control measurement system, respectively; the gas source division system and the temperature segmentation system and the vibration division system are connected separately;Performance test.Compared with a single stress, it has the characteristics of more real environmental simulation and higher test efficiency.
Description
technical field [0001] The invention relates to a simulated environment test system, in particular to a comprehensive test system which superimposes temperature environment, mechanical environment and air source environment, and is mainly suitable for aerospace products. Background technique [0002] More and more aerospace products require that the simulated environmental test be closer to the environment in which the product's real working state is located. The test under the action of a single environmental stress will not be able to effectively assess the performance stability of the product's actual working state, even in In the initial stage of product development, the multi-stress environment simulation test has become very important. According to the test technical requirements of aerospace products, the test needs a comprehensive test system that not only meets the single stress test, but also meets the multi-stress superposition. Contents of the invention [000...
