摘要
振动控制是振动工程领域的一类重要问题。随着隔振要求的提高,研究考虑系统柔性的分布参数连续体的振动问题显得尤为重要。用梁结构模拟振源和基础,建立柔性系统的模型。从系统的传递路径角度,根据功率流法讨论柔性系统的振动传递关系,并讨论弹簧刚度以及不同的基础边界条件对振动及功率流的影响。为柔性系统的振动传递特性的预测以及系统的振动控制提供有效的途径和依据。
Vibration control technique is a key problem in the recent research field of vibration control engineering.Firstly,to take account of flexibility of both machines and supporting structures,a flexible system model is established where both machine and foundation is beam structures.Then,with a power flow transmissibility method,the vibration transmission paths in the system are studied.And the influences of different stiffness and boundary conditions on the transmission power are also discussed.Those can prov...
