Aiming at this problem, firstly, calculation formulae of utilization adhesion coefficient after installment of retarder were detailedly deduced. Then braking force distribution ratio , braking intensity and vehicle full-load parameters were taken as variables and inequalities which are about of retarder braking force , braking force distribution ratio , braking intensity and vehicle full-load parameters were established based on the ECE Law. The range of corresponding to any , as well as the most optimal matching between them, were obtained by solving these inequalities.

For the highway bridges with small or medium span, their vibrations were excited usually by a single vehicle, and the vehicle will stay on the bridge after excitation, so analytical expressions of the frequencies of the bridge under the action of a single vehicle were derived.

对于中小跨径的公路桥梁，往往采用单个车辆激振桥梁，激振后停于桥上，因此推导出了单个车辆作用下的桥梁有载频率解析表达式。

In order to meet the needs of automobile crashworthiness during the design, thin walled beam's components in automobile structure were taken as research objects. Aiming at collision deformation characteristics, HyperMesh and LS-DYNA were used to simulate the collision process here.

Using the models, the author has also calculated the vibration response to high speed railway vehicles of three types travelling over simply-supported beam bridges with various span lengths respectively. Based on the analysis of the computation results, the concept of resonance velocity of a bridge under a high speed running vehicle is present, and it is pointed out that comparatively great vibration of bridges on high speed railways is caused by bridge resonance resulted from the static force pulsating. In a vehiclebridge coupling vibration system, the damping constant of the axle spring is the main factor affecting the response variable of bridge velocity resonance, and the influence of track irregularity on bridge vibration on high speed railways is rather smaller.
