Abstract
The common problem of static calibration and dynamic measurement remaining in domestic air-craft landing gear load measurement,the causes of static calibration in dynamic load measurement by strain method are analyzed theoretically and mechanically.At the same time,the focuses,in consideration of carrier based aircraft being subjected to severe dynamic loads due to fixed point landing,is on the static and dynamic measurement of impact loads on carrier based aircraft landing.By simulating the process of aircraft landing through dynamic drop tests and analyzing the measured load on the force measuring plat-form,the degree of influence of dynamic load on the accuracy of strain method measurement is obtained,and an improved inertia correction method is proposed.The identification of the mass matrix is done by the drop test data,and the correction of the measured load is made by the strain method through the identified mass matrix and measured acceleration.The experimental results show that the improved inertia correc-tion method further improves the measurement accuracy of vertical loads and significantly improves the measurement accuracy of heading and lateral loads.关键词
