摘要/Abstract

摘要： 针对冲压发动机中高温板壳结构的振动抑制需求，提出新型颗粒金属橡胶夹层阻尼结构，基于模态应变能法建立了其动力学理论模型和数值求解方法。与试验结果对比表明，共振幅值的相对误差不大于20%。进一步采用理论分析与试验相结合的手段，论述了颗粒型金属橡胶夹层阻尼的有效性，可有效降低振动响应3～8倍；随着填充密度的增加，减振效果增加；对于一弯和二弯振动，下部填充减振效果最好，而在下部填充，振动响应会被放大；依据数值计算获得的应变能分布结果，进行夹层设计可达到良好的减振效果。

Abstract: According to the vibration control requirement for the high temperature shells used in ramjet engines， a novel sandwich configuration with particle metal rubber damper was put forward. The dynamical theoretic model and numerical method were erected based on the modal strain energy method， and the experiment results revealed that the relative errors for the resonance amplitude were less than 20%. The theoretic and experimental results show that the particle metal rubber damper was effective， and could depress the vibration amplitude by 3 to 8 times. The depressing effect increases with increasing the filling density. The root filled was best for the first bending mode and the second bending mode， and the tip filled would amplify the vibration response. It was effective to design the configuration parameters based on the strain energy distribution results.
