Structural Design of New Generation Fuselage Panel Compression and Shear Load Test-Bed
In view of the loading space fixed size of the traditional fuselage panel compression shear test-bed,a new generation fu-selage panel compression and shear load test-bed was designed.lt can adjust the loading space according to the length of fuselage pan-els,which is suitable for the compression load+shear load test of fuselage panels with different lengths.The design scheme of the test-bed was introduced,the key mechanism design method was proposed to realize the core function of the test-bed.Then the function of the test-bed was debugged.The function of key mechanism is normal,which can meet the use requirements.Using the test-bed to simulate the loading of the test dummy,the linearity of the loading process is good,which proves that the loading method of the test bench is rea-sonable.The uniformity of strain distribution of the test dummy is good,which proves that the accuracy of the test bench meets the re-quirements.
