Effect of falling height on impact coefficient during dynamic response of truss structure

摘要

Impact coefficient is an important parameter for the dynamic response of the truss structure.An effective method to analyze impact coefficient helps the design of truss structure.A finite element model(FEM)was employed to simulate the dynamic response of a truss structure.The FEM for dynamic response was further used to research the effect of falling height on the impact coefficient.Based on the numerical results,the dynamic response of truss structure attenuates greatly.The impact coefficients are different from each other for different falling heights.The impact coefficient increases with the increasing falling height and the relationship between impact coefficient and falling height are nonlinear.
