摘要
在考虑阻尼影响的基础上,采用线性振动理论研究了动载荷问题的冲击计算.利用振动方程推导出了结构动位移、动载荷系数、冲击时间的表达式,并讨论分析了结构阻尼对动载荷问题的影响.
Impact calculation problem of dynamic load was studied by using linear vibration theory based on considering the effect of damping. The function expressions for structural dynamical displacement, factor of dynamic load and impact time were derived by using the vibration equation. And the effects of structural damping on dynamic load problem were discussed and analysed.
