【摘要】 应用能量法对含磁流变液(MRF)的简支梁在不同磁场作用下的振动特性进行了理论研究,并用实验验证了理论结果。结果表明,理论分析与实验结果吻合较好。随着磁场强度的增高,结构的固有频率和损耗因子增大,说明磁流变液在外加磁场的作用下对夹层梁有显著的抑振作用。更多还原

【Abstract】 The theoretical investigations is performed to the vibration characteristics of sandwich beam with MR fluids in different magnetic field based on the energy approach, and the theoretical investigations is validated with experiment. The results show that the natural frequency and loss factor of the MRF beam increase with increasing the applied magnetic field, indicating that the vibration of sandwich beam with MRF is effectivly suppressed in applied magnetic field.更多还原
