医疗器械生产车间楼面振动的探讨

Discussion on the Medical Production Workshop Floor Vibration

针对医疗器械生产车间振动盘设备振动对楼板的影响问题,在分析设计资料和现场勘查基础上,结合振动测试收集车间楼面振动响应数据,结果表明：楼盖振动较为强烈,不容忽视.运用通用有限元分析软件对楼板的进行振动特性分析,得到楼板频率范围在30 ～ 70Hz之间为振动响应高峰值区域,设备运行时的激振频率较难避开结构固有频率.数值分析与实测结果较为一致,因此,为确保结构安全,需采取有效的防振手段和加固措施.

To solve the problem of medical instrument workshop vibration plate equipment vibration on the floor, Through the analysis of design data and field investigation, and the reference vibration test collection workshop floor vibration response data, results show that： the floor vibration is strong, cannot be ignored. Using the finite element analysis method on the floor of the vibration characteristic analysis, structural frequency response peak area for the vibration between 30Hz-70Hz, the excitation frequency operation of the equipment is difficult to avoid the resonance frequency. The results of numerical analysis arc consistent with test. In order to ensure the structural safety, should adopt effective anti vibration and reinforcement measures.
