【摘要】 以某小区水泵隔振治理为例,应用功率流理论对水泵隔振系统中的参数对基础振动的影响进行研究。将水泵隔振系统简化为单层隔振系统的功率流隔振模型,依据电-力类比的方法,通过编写的Mat-lab应用程序,计算并绘制了质量块有无、质量块质量变化和基础区域面密度对传递到基础的功率流和振动速度的影响曲线。研究表明,质量块对基座的速度和功率流有明显的降低,增加质量块质量对幅值降低的影响不明显,增加基础区域面密度有利于隔振。更多还原

【Abstract】 Regarding a dwelling water pump vibration isolation as a case,The vibration power flow theory is applied to conduct the research on the effects of vibration parameters of water pump on the basement vibration.Water pump vibration isolation system can be simplified to be a single-deck isolation system power flow model.By using E-F analog picture method and adjusting the parameters such as intermediate mass and area density,the curves of foundation speed amplitude and power flow are drawn by using Matlab calculating program.The results show that the intermediate mass has clearly reduced the vibration power flow and speed amplitude,the vibration parameter of intermediate mass only has little effect on the vibration amplitude and the isolation vibration effect can be improved by increasing area density of the basement.更多还原
