Unsteady Aerodynamic Simulation Test Based on Ampere Force and Electromagnetic Field

Abstract

Unsteady aerodynamic force refers to the aerodynamic force that the magnitude and direction of the load borne by the aircraft will change with time during flight. Usually, the simulation of unsteady aerodynamic force is completed by wind tunnel test. This paper introduces a new load simulation method based on electromagnetic field and Ampere force. Compared with the traditional wind tunnel test method, electromagnetic field load test will greatly reduce the test cost and make it possible to repeat multiple tests. In order to verify whether the test method is feasible and effective, this paper introduces a number of verification tests, including static load test and dynamic quasi modal test. By comparing the ground test results with those based on ABAQUS simulation, the reliability of the test method is verified. In this test technology, electromagnetic technology is used to study the force of structure, which is of great significance for multi physical field test and aircraft design test.
