摘　　要：针对传统机身壁板压剪试验台加载空间为固定尺寸的问题,设计一种新一代机身壁板压剪载荷试验台。它可以根据机身壁板长度调节加载空间,适用于不同长度机身壁板压缩载荷+剪切载荷试验。介绍试验台设计方案,提出试验台核心功能的关键机构设计方法;对试验台进行了功能调试,各关键机构功能正常,满足使用要求。利用试验台对试验假件进行模拟加载,加载过程线性度良好,证明试验台载荷施加方法合理;试验假件应变分布均匀度良好,证明试验台精度满足要求。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.It 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 testbed 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.
