摘　　要：杠杆加载系统的设计作为静力试验设计中的重要部分,除了保证加载精度、杠杆强度外,还应该检查杠杆系统的干涉情况以及与试验结构的组装。而传统方法对于大型静力试验杠杆系统的设计显得繁琐且效率低下。因此,针对直升机大型静力试验数量繁多的杠杆加载系统,基于EXCEL VBA技术和CATIA二次开发技术,结合杠杆原理和载荷系数法原理,提出了直升机杠杆加载系统自动化设计以及自动化建模方法。与传统设计方法相比,该方法极大地提高了杠杆加载系统的设计效率和设计精度,缩短了前期试验设计时间。The lever load system design as an important part of the test design, in addition to guarantee accuracy of loading, the lever strength, can also check of the assembly interference of lever system and the test structure. But the traditional method for the calculation of large lever system is cum? bersome and inefficient. Therefore, aimed at large number of the lever load systems of helicopter static test , based on EXCEL VBA and load coefficient method, this paper proposed automation design and automation modeling of helicopter lever load system. Compared with the traditional method, the program could greatly improve the design efficiency and accuracy of the lever load system, shorten the time of pre experiment design.
