高速铁路简支梁桥参数变化对竖向共振影响分析
Analysis on the vertical resonance effect of simply-supported beam bridge para meters on High-speed railway
摘要
Abstract
Based on the finite element analysis theory of the vertical vibration on train-slab track-bridge system, this paper obtained the vertical dynamic equation of high-speed train-slab track-bridge system,with the help of the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-posi-tion"rule for formulating matrices.The inflence of the railway simply supported beam bridge structure parameter on the bridge vertical resonance was analyced voriation of the numerical results show that bridge’s span,damp-ing,stiffness and quality parameters changes have an important impact on bridge vertical resonance.The results can provide a reference for optimizing the High-speed railway Simply-supported bridge structure and improving the safety factor of train operation.关键词
