Airplane porthole component performance test system

Abstract

The invention discloses an airplane porthole component performance test system comprising an industrial control computer, a programmable logic controller, an airplane porthole component test device, and an air source. The industrial personal computer is used for being connected with the programmable logic controller, transmitting a pulse signal of controlling the airplane porthole component test device, and receiving a current signal, processed by the programmable logic controller, of the airplane porthole component test device. The programmable logic controller is used for receiving a pulse signal whereby the industrial control computer controls the airplane porthole component test device, and receiving and processing the current signal from the airplane porthole component test device. The air source is used for providing the airplane porthole component test device with air. The airplane porthole component performance test system is capable of effectively simulating flight temperature and pressure parameters of an airplane, is capable of truly indicating the physical performance of airplane porthole glass during actual operation and the influence of component assembly upon the performance of the airplane porthole glass, is also capable of automatically intercepting and storing test data in performance test process into the industrial personal computer, and has an extensible test function.

Description

technical field [0001] The invention relates to a test system, in particular to a test system for the performance of an aircraft porthole assembly. Background technique [0002] For the performance test of aircraft porthole components, currently at home and abroad, the deformation and failure behavior of aerospace plexiglass samples after tension, tension and compression at different temperatures are generally studied and analyzed based on the testing methods of material mechanical properties. There is a big difference in the situation, and it cannot truly reflect the physical performance of the aircraft porthole assembly in actual work. At the same time, the research objects are concentrated on the porthole glass material itself, ignoring the impact of the porthole glass assembly on its performance. [0003] Aircraft porthole components must be repeatedly exposed to harsh environments where the temperature and air pressure change during aircraft flight for a long time. Due ...
