Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 A test device for simulating the service environment of aviation components is shown, including a power supply 1, a main control system 2, a salt spray generation system 3, an environmental control system 4, a test system 5, and a salt spray test chamber 6. The salt spray The generating system 3, the testing system 5, and the environmental control system 4 are located inside the salt spray test chamber 6, the main control system 2 is located outside the salt spray test chamber 6, and the test system 5. The main control system 2 and the environment control system 4 are connected sequentially, and the main control system 2 is connected with the salt mist generating system 3 .

[0020] Such as figure 2 A test device for simulating the service environment of aviation components is shown, and the salt mist generation system 3 includes an air com...

Abstract

The invention relates to a device for testing simulation aviation member service environment, which comprises a power supply, a main control system, a salt spray generation system, a testing system, an environment controlling system and a salt spray test box case, the salt spray generation system, the testing system and the environment control system are positioned in the salt spray test box case, the main control system is positioned outside the salt spray test box case, the testing system, the main control system and the environment control system are connected in order, and the main control system is connected to the salt spray generation system. The device of the invention can reflect the real environment condition of an airplane real service environment, can perform acceleration test, and can greatly shorten the test period.

Description

technical field [0001] The invention belongs to the technical field of material analysis equipment, and in particular relates to a test device for simulating the service environment of aviation components. Background technique [0002] The corrosion damage of metal spreads all over the national economy, causing very huge economic losses. In the United States, the loss caused by corrosion accounts for about 4.7% of its national economic output. During the Eleventh Five-Year Plan period, the direct or indirect loss caused by corrosion in my country is about 2 trillion yuan. Due to the harsh service environment, the hazards of corrosion damage are more obvious in the aerospace industry. According to statistics, in the 10 years from 1994 to 2004 in the United States, about 100 million average maintenance man-hours per year were used to solve corrosion and corrosion inspection work. An average of 7.6 maintenance hours / flight hours, accounting for 36% of the entire inspection a...
