悬臂梁受冲击载荷作用形成的超静定问题

The Hyperstatic Problem in a Cantilever Beam Under Impact

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。

This artide discussed the hyperstatic problem in a cantilever beam under impact.The system under impact is reduced to a model of a spring by using the corresponding relationship between the load and the displace ment A thorough discussion of the problem was made from the energy angle and formulas were given to find out the coefficients of dynamic load corresponding to the cantilever beam ,sendpoint under various conditions.The checking computation shows that the formulas given in this artide are correct.They can be directly applied to the relevant engineering structure,and they are of some value in the engineering.
