基于SIMPACK和ANSYS联合仿真的胶粘道砟过渡段动力学特性研究
Study on Dynamic Characteristics of Bonded Ballast Transition Section Based on SIMPACK and ANSYS Co-simulation
摘要
Abstract
In order to study the dynamic characteristics of the bonded ballast transition section,a complete transition section is established to connect three different track structures of ballastless track,bonded ballast and ballast track based on SIMPACK and ANSYS co-simulation and a vehicle-track spatial coupling analysis model is formed to study systematically the dynamic characteristics of the transition section of the bonded ballast and address the influence of the speed.The results show that the transition section of the bonded ballast can make the track stiffness transition smoothly,but the acceleration may change drastically when the train runs from the ballastless track to the bonded ballast.Therefore,the damping fastener in the ballastless track near the bonded ballast transition section is recommended.关键词
