引言具有冲击荷重的机械设备,多半属于锤类机械。按其构造及功用的不同,普通可分为两种——锻锤和模锻锤。其二者区别之点在于:锻锤的机座与砧子是分离的,而模锻锤的机座与砧子乃为连结在一起的整体联系。正因为锤机械造构有这样的不同,其基础的型式亦随之而异。通常,将锻锤基础设计成箱式及模锻锤基础设计成平板式,如图1a、1b所示。锤机械在工作时,将产生较大的冲击荷重。若对锤基础本身或其相邻建筑物设计不常时,除了防碍机械及基础正常工作外,对其相邻建筑物亦有很大的损害,严重者,可使附近建筑物完全破坯。因此,研究‘冲击荷重机械基础振动对建筑物的影响’这一个问题是很重
Introduction Mechanical equipment with impact loads is mostly a hammer machine. According to their different structures and functions, they can be generally divided into two types - hammers and die hammers. The difference between the two is that the base and hammer of the hammer are separated, and the base and anvil of the hammer are connected together. It is precisely because of the differences in the construction of hammer mechanics, the basic types of hammers also vary. In general, the foundation design of the forging hammer is a box type and the foundation of the die forging hammer is designed as a flat plate type, as shown in Figs. 1a and 1b. When the hammer machine is working, it will produce a larger impact load. If the design of the hammer foundation itself or its adjacent buildings is infrequent, besides impeding the normal operation of machinery and foundations, it will also cause great damage to its adjacent buildings. In severe cases, the nearby buildings can be completely broken. . Therefore, it is very important to study the issue of ’impact of impact on the building’s impact caused by vibration of mechanical foundations’.
