Abstract:
This art ide discussed the hyperstatic problem in a cant ilever beam under impact . T he system under impact is reduced to a model of a spring by using the corresponding relationship betw een the load and the displace-ment A thorough discussion of the problem was made from the energy ang le and formulas w ere given to f ind out the coefficients of dynamic load corresponding to the cantilever beam , sendpoint under various conditions. The checking computat ion show s that the formulas given in this art ide are correct. T hey can be direct ly applied to the relevant engineering st ructure, and they are of some value in the eng ineering .
