主要的工業震动来源之一,就是冲击机器——鍛錘、落錘等的工作。基础的震幅,以鍛錘为例,可能达到很大的数值——1.5公厘及1.5公厘以上。錘基础附近土及承重結構(柱、牆等)基础的震幅,也差不多是这样的数值。 錘基础之震动所引起的承重結構基础地基土上的附加动载荷,会使基础發生危險的不均衡下沉,使構筑物本身产生严重的变形。鍛錘的工作也經常破坏正常的工艺过程,防碍使用精密測量仪表的工厂实驗室的工作。
One of the major sources of industrial vibration is the impact machine - hammer, drop hammer and other work. The amplitude of the foundation, forged hammer, for example, may reach a great value - 1.5 mm and 1.5 mm above. Hammer near the foundation soil and load-bearing structures (columns, walls, etc.) based amplitude, but also is almost such a value. Hammer based on the vibration caused by the foundation of the load-bearing structure of the foundation of the additional dynamic load on the foundation, will make the foundation dangerous imbalanced sink, so that the structure itself produces serious deformation. Forging hammer work often undermines the normal process, hindering the work of factory laboratories using precision measuring instruments.
