摘要
讨论了一种估算立柱、千斤顶在安装安全阀和不安装安全阀两种条件下受自由下落重物冲击时产生的冲击载荷和冲击时间的数值计算方法。计算时考虑了立柱、千斤顶的相关质量及摩擦,编写了相应的计算程序。
This paper discusses a calculating method for the impact loads of the post and jack when they are impacted by the free-falling heavy objects on the condition that the safety valve is installed or not. During the calculation, the corresponding procedures are written by taking into account the related quality and friction of the post and jack.
