摘要
要给出了水平轴风力发电机塔架的设计依据，利用有限元方法对塔架进行了分析，理论计算结果和实验结论相符，建立了桁式塔架结构优化的数学模型。
Gives the basis of HAWT tower design. Several finie element models of tower are built, the results calculated are quite correlated with the test data. The Optimum model of truss type tower and solving process are also pressented.
