一、前言目前锻锤已被广泛应用,但是,锻锤引起的强烈振动使工作条件严重恶化,特别是大型锻锤给厂房施加的动载将会导致基建投资的增加。由于基础的隔振参数选择不当,甚至振坏厂房。因此,新设计的锻锤基础应该选择合理的隔振参数,目前正在使用的锻锤,如果基础振动过大,应在设备大修时,采用隔振基础,以达到改善劳动条件和延长厂房的使用期限。为了计算锻锤基础给地基的载荷,需要确定锤锻时基础的运动规律。早期文献曾用机械阻抗法计算基础振幅,但此法只能算出稳态振幅,而锻锤基础实际是作非稳态运动。为此,后期文献多数把锤头对锻件的打击力简化为瞬时碰撞,根据试验观察结果确定碰撞恢复系 I. Introduction At present, forging hammers have been widely used. However, the strong vibration caused by forging hammers seriously worsens the working conditions. In particular, the dynamic load applied by large forging hammers to the plant will lead to an increase in capital investment. As the basis of the vibration isolation parameter selection, or even vibration bad plant. Therefore, the newly designed forging hammer foundation should select reasonable vibration isolation parameters. At present, forging hammer is used. If the foundation vibration is too large, the vibration isolation foundation should be used when the equipment is overhauled to improve the working conditions and prolong the use of the plant the term. In order to calculate the foundation load of forging hammer foundation, it is necessary to determine the movement rule of foundation hammer forging. Early literature used mechanical impedance method to calculate the basic amplitude, but this method can only calculate the steady-state amplitude, while the hammer foundation is actually used for unsteady motion. To this end, most of the late literature hammer forging of the striking force reduced to instantaneous collision, according to the experimental observations to determine the collision recovery system
