摘　　要：在试验中，采用正弦稳态激振、随机激振和中向正弦波低幅共振，研究了正放四角锥网架模型的动力特性；在理论上，采用子空间迭代法求解网架结构的自振频率和振型，并绘出了振型图，最后把试验结果与理论计算结果进行了比较，得到了令人满意的结果。Dynamic characteristics of space trusses have been traced in the laboratory by three experimental test techniques. Subspace iteration method is utilized to analyse vibration modes and frequences of space truss structures and vibration mode curves are also plotted. Comparison of experimental results with those of theoretical solutions gives a favourable agreement.
