The Stable Type Suspension Bridge is on the basis of the general suspension bridge increases the inverse-tensional system, in order to improve the stability of the whole bridge.Using finite element software respectively in Stable Type Suspension Bridge and ordinary suspension bridge under the action of movement, moving load under the action of quality and a quarter spring quality vehicle model under the action of three kinds of vehicle bridge coupling finite element analysis, draw the corresponding displacement response and acceleration response.In stable suspension stiffness and stability more is better than that of normal suspension bridge, for the analysis and research of the stability of suspension Bridges provide certain reference value.
