摘　　要：介绍了直升机静力试验加载杠杆系统配重计算的必要性,包括杠杆系统重心偏离合力中心而引起的后果以及消除该后果的处理方法。然后介绍了载荷系数法的原理以及在大型静力试验中的应用情况。结果表明,利用载荷系数法进行杠杆配重计算,并在加载合力点进行集中扣重,能够消除杠杆系统重量对试验加载的影响,保证试验加载精度。This paper introduced the necessary and method to calculation the counterweight of lever system, and the aftermath when the gravity center of lever system deviating from the combined force center, the method to solve the aftermath was provided also. Then, the paper introduced the principle of Load-Coefficient-Method and its application in static test of large-scale structure. The results showed that using the Load-Coefficient-Method to compute the counterweight of lever system and deduct the total weight at the combined force center of lever system could eliminate the weight effect of lever system to the required test load and improve the test precision.
