Based on ANSYS Analysis of Suspension Bridge Transient Dynamics

Abstract:

By using the finite element analysis software ANSYS to do the first 10 order modal analysis of suspension bridge, obtaining the natural frequency and natural vibration model, to avoid the structure has resonance phenomenon. The results show that inherent frequencies of the first 10 order of the suspension bridge are far less than the excitation frequency of vehicle, the speed of mobile has obvious influence on the mid-span nodes deflection, when the vehicle goes through the suspension bridge, it usually travels at low speed; vehicles traveling at the same direction have a greater impact on the suspension bridge structure, the maximum mid-span node deflection of the suspension bridge decreases with the increasing of angular frequency.
