The comparison of experiment with theory of torsional composite lumped parameter model
摘要
Abstract
A new torsional composite lumped parameter model ( CLPM ) of surface foundation was established based on the theory of foundation oscillation on a elastic half - space. Free vibration of two different shaped base lumped foundations perturbed by the initial velocity was achieved respectively. Compared the results of experiment with the results of calculation performed with CLPM, they are dosed agreement. The analysis results show that the advantage of CLPM is to compute dynamic response of arbitrarily shaped surface foundations torsionally oscillating on a homogeneous half - space readily. Moreover, all of oscillation frequencies and all foundation base shapes( excluding annular)are included in the analysis.关键词
