摘要
本文利用Ｒａｙｌｅｉｇｎ法预测结构再设计后的动态特征的变动情况，采用多方案比较法确定了满足设计要求的最佳方案，并利用模态实验法对该理论和所研制的软件进行了验证。结果表明：该方法具有节省时间和费用的突出特点，特别适用于目前国内产品的改进和开发，具有广泛的工程实用价值。
This paper forecasts the variation situation of dynamic properties for structures after redesigning by the utilization of Rayleign method,determines an optimum plan which meets the requirement of design by adopting the comparison method of multi plans and a verification has been carried out on this theory and the developed software by utilizing modality testing method. The result shows that: this method possesses outstanding properties on the saving of time and cost,especinlly suitable for the improvement and development of present domestic products and it has broad pratical value in engineering.
