摘要
针对某飞机机翼载荷校准试验遇到的现有加载设备难以满足试验要求的问题,提出并研制出基于真空吸盘技术的加载系统,成功完成机翼多点小载荷协调加载试验。结果表明,采用吸盘技术的加载系统,能更真实地模拟机翼实际受载情况,降低试验风险;试验数据可靠,载荷模型精准度满足要求,可为后续同类机型校准试验提供良好借鉴。
Aiming at the problem that the existing loading equipment is not able to meet the test requirements in a certain aircraft wing load calibration test,a test loading system based on vacuum suction cup technology is proposed and developed,and successfully applied to the aircraft wing load calibration test of multi-point and small load coordination.The results show that the loading system using suction cup technology can simulate the actual load of the wing and reduce the test risk.The test data is reliable,the precision of the load model meets the requirements.It can provide a good reference for the calibration test of the same type of aircraft.
