摘　　要：本文根据某塔机的双吊点水平动臂的实际参数,进行了其线性和非线性计算,并对其结果进行了较分析。由于篇幅有限,仅对最大起重量工况进行了计算,其他工况读者可以仿照进行计算。According to actual elements of two-hanging point horizontal boom of tower crane, the linearity and, nonlinearity were calculated and the calculated results were analyzed. Because of limited space, we only calculated on operating conditions of maximum loads. On other operating conditions cal-culations will be done by readers themselves following this example.
