摘要
把线弹簧模型应用到框架中,研究不同裂纹长度和裂纹位置对框架的固有频率的影响,并把计算数据与现实的数据进行比较,结果证明,该模型应用到框架结构是可行的,同时分析线弹簧模型的局限性。
It researches influencing of different length and position of crack to natural frequency of frame which applying for line spring model, and compares calculating data with experimental data, the result indicates the model is feasible. At the same time the limitations of spring model are talked about.
