分析了螺旋压力机的致振原因，提出了冷击和锻打工件时冲量矩、冲量的计算方法，所得结论可供振动分析、隔振设计及基础设计时参考。对Ｊ５３—３００型双盘摩擦压力机的隔振计算表明：惯性块下螺旋弹簧和油阻尼器承垫式隔振基础可有效地吸收摩擦压力机工作时产生的冲量矩和冲量，使基础的振动加速度降为隔振前的１／１２５。 The cause of vibration induced by screw press is analyzed, and the calculation methods of impulse moment and impulse at cold work and forging work are put forward. The conclusions are available for vibration analysis, vibration isolation design and reference for basic design. The vibration isolation calculation of J53-300 double disc friction press shows that the inertia block under the coil spring and the oil damper bearing cushion isolation foundation can effectively absorb the impulse moment and impulse generated when the friction press work, The vibration acceleration is reduced to 1/125 before vibration isolation.
