把柴油机机脚螺栓连接简化为双弹簧模型，将其与设备一起简化为单自由度系统，结合等效弹簧的柔度曲线规律，设定了机脚螺栓连接的冲击失效判据，并建立了系统的冲击动力学方程。在这一过程中找到了一种快速判断机脚螺栓连接抗冲击性能的方法。

A double-spring model for bolted joints was introduced as the model of engine bracket bolts and the system integrating the equipment and the bolted joints was considered as a one degree of freedom system.Taking into account the effect of interface opening on the elastic behavior of bolted joints,a disabling criterion for bolted joints under impact load was proposed.The dynamics equation of the system was built and a fast computation method for the limit shock load of engine bracket bolts was presented.
