摘要 通过分析两种不同类型载荷对带线性缓冲材料的弹性直杆的撞击,得到撞击条件下杆体屈曲发生的临界弹簧刚度。结合具体材料进行计算,分析了临界弹簧刚度与载荷作用时间、载荷幅值、缓冲材料和杆体长度的关系,以及缓冲材料位置对于杆体屈曲防护的影响等。所得结论为解决在不同冲击载荷作用下弹性直杆的动态屈曲防护问题提供了理论依据。 It analyzes the impact of two different types of load to elastic straight rod with linear buffer material,obtains the critical buckling spring stiffness of rod body under the condition of impact. Taking the rod material as model parameter,it simulates the relationship between critical spring stiffness with the load time,load amplitude with cushioning materials and the length of the rod. The result provides the theory reference for dynamic buckling protection of elastic straight rod under the different impact load.
