As a studied object ,we must do dynamic analysis for a crane . By modeling and soluting ,we can know about response of each part,and analyse probability of second impact .
作为研究对象,我们必须对起重机进行动力分析,通过建模和求解,了解起重机结构各部分的响应情况,并分析“二次碰撞”的概率。

“二次碰撞”是造成人体损伤的直接原因,但“一次碰撞”在很大程度上决定了“二次碰撞”的剧烈程度,因此“一次碰撞”对人体损伤有很大影响。

On this second impact the left wheel strut broke and the right tire blew out!
这第二次接舰的时候,左起落架支柱折断,右轮胎也爆了!
The central crater could be formed by unusual layers below the surface, or from a lucky second impact.
陨坑中心可能是由于不同寻常的下层地质结构导致的,也有可能因为幸运的二次撞击而形成的。
Third, granular-mass loading stratum descended after a while , which brought second impact load, the interval among the three courses was short.
