航空發(fā)動(dòng)機振動(dòng)試驗

THE 1000KN ELECTRO-DYNAMIC VIBRATION TEST EQUIPMENT IS THE WORLD'S LARGEST ELECTRO-DYNAMIC VIBRATION TEST EQUIPMENT BY SINGLE THRUST.

Funded by the national major scientific research instrument development project, etc., the world's largest thrust ES-1000 (1000kN) electric vibration testing system was developed by industry-university-research cooperation and independent innovation, which meets the testing needs of large-scale equipment development for national major projects in aviation, aerospace and other fields in China. The main technological innovations are listed as follows:

1. The ultra-large thrust lightweight high-strength moving coil structure and the reliable steering technology of the moving coil were invented, and the ultra-large power amplifier was devoted, which solved the problem of ultra-large thrust actuation of the electric vibration testing system.

2. The double helix coil coupling method with merits of reducing the voltage and suppressing the temperature for ultra-large power actuating system was proposed, the adaptive and efficient cooling control technology for the moving coil was invented, and the parallel cooling system for ultra-large power actuating system was developed, which solved the high-efficiency cooling problem of the ultra-large thrust electric vibration testing system.

3. The current equilibrium control method for parallel ultra-large power amplifiers was proposed, the high-precision power spectrum reproduction control technology subject to strong load disturbance was invented, and the full-state visual monitoring platform of the testing system was developed, which solved the problem of high-performance operation control of the ultra-large thrust electric vibration testing system.

The achievements of the project have been successfully applied to the vibration testing of large spacecraft and aircraft engines, and have been publicized and reported by mainstream media such as CCTV, CNR and Science and Technology Daily, etc., which brings in remarkable economic and social benefits. The overall level of the project has reached the international leading level by appraisal.
