我国建筑业的蓬勃发展,伴随的也有安全隐患问题,工程中的振动问题亟待解决,大型厂房里很多动力设备对周边环境及厂房自身的影响巨大,造成的损失更是难以计数。为了生产的需求,厂房里往往都配有大型的动力设备,往往因机器结构的老化、设计的疏忽、设备更新的缓慢等原因,动力设备的振动往往对厂房的结构有着不可忽视的不利因素,尤其是厂房大底,严重时有可能对厂房的结构产生毁灭性的打击。解决结构振动的核心问题在于找出振动的原因。而伴着振动测试理论的发展,数据分析方式的完善和分析仪器的改进,现如今,结构振动测试的主要手段是结构动力测试。通过这个测试,能得出结构的阵型,阻尼系数,固有频率等动力数据,从而对机器结构进行评估,找出振动原因,采取相应的对策,减少振动。
The vigorous development of China’s construction industry, accompanied by potential safety problems, the vibration problem in the project needs to be solved urgently. Many power plants in large plants have a huge impact on the surrounding environment and the plant itself, making the loss even more difficult to count. In order to meet the demand of production, large-scale power equipment is usually equipped in the factory, often due to the aging of the machine structure, the negligence of design and the slow renewal of the equipment. The vibration of the power equipment often has unfavorable unfavorable factors to the plant structure, Especially in the factory outsole, serious may have a devastating blow to the structure of the plant. The core problem in solving structural vibration lies in finding the cause of the vibration. With the development of vibration testing theory, data analysis methods and the improvement of analytical instruments, nowadays, the main means of structural vibration testing is structural dynamic testing. Through this test, we can get the dynamic data of structure, damping coefficient and natural frequency so as to evaluate the structure of the machine, find out the reason of vibration, and take corresponding countermeasures to reduce the vibration.
