该文就悬臂梁受冲击载荷作用形成的超静定问题，利用载荷与位移之间的对应关系，把受冲击系统简化为一弹簧模型，从能量的角度出发，进行了全面的讨论，并给出悬臂梁端各种情况下所对应的动荷系数的求解公式，并对这些公式进行了验算。结果表明，公式正确，这些求解公式对工程中的相应结构可连接应用，因此有一定的工程意义 In this paper, the cantilever beams are impacted by the impact of the formation of the indeterminate problem, the use of load and displacement of the correspondence between the impact of the system is reduced to a spring model, from the energy point of view, a comprehensive discussion and give The cantilever beam end corresponding to the dynamic load coefficient of the formula, and these formulas were checked. The results show that the formulas are correct and these formulas can be applied to the corresponding structures in the project, so it has certain engineering significance
