摘要
针对基于灵敏度分析的结构动力修改方法在实际应用中的不足之处,改进了用于计算的公式,使之能够直接指导工程实践。另外,本文还给出了具体算例,对铰接式高速客车车体的局部结构进行了修改,使其固有频率得到了提高。同时,本文还提出了基于灵敏度分析的结构动力修改的一般步骤,具有较大的实际意义和应用价值。
This paper put forward an improvement on the method for structural dynamics modification based on the sensitivity analysis to use it in the practice. As an example, a partial structure of car body of the articulated high speed passenger train is modified to increase its natural frequency. At the same time, a general step of the modification is presented, it has considerable practical worth.
