| 摘 要： | 原设计为展览功能的大跨度楼板改造为文艺演出场地后,楼板振动过大,无法满足舒适安全使用要求。通过对该部位楼板模拟演出激振实际检测,并进行有限元分析,得出楼板的振动频率和动荷放大系数,在舞台部位采用橡胶隔振器,大幅度降低楼板振动反应。经过演出现场测试,隔振效果明显,满足了安全和舒适使用要求。

| Abstract: | After the original design of large-span floor for the use of exhibition changed to entertainment,the vibration of floor is too large and the demand of comfortable and safe use can not be satisfied.Through the actual check of simulated performance on the floor and finite element analysis,the vibration frequency and amplificatory factor of dynamic loads are carried out.By using the rubber vibration isolator on the stage,the vibration response of the floor can be greatly reduced.Through the test of local perfo... |
