Abstract

By intercepting a limited range of subgrade and imposing an artificial boundary on the boundary of the subgrade, structural designers can complete dynamic machine foundation-subgrade dynamic interaction calculations with existing structural analysis software and finite element analysis software. Based on elastic wave theory, the calculation equations for spring and damper elements of artificial boundary nodes are derived. After proper simplification, only the subgrade parameter is included in the equation for ease of use for designers. Numerical simulation results show that when the subgrade range is 10 times the foundation size, the design accuracy requirements can be met and the calculation efficiency is high.
