Treatment of Vehicle Load and Axle Load Model

Base on analysis of axle load model of vehicle,coefficient of axle load application is set up by this research,the concept has ability what illustrate affect of mechanics and characteristic of traffic more clearly;the data of lorry's axle load as sample,and statistic as tool,the new model of axle load is set up by the paper too.It is shown that weather normal or heavy traffic,lorry 's axle load of single wheel which single axle,double wheels which single axle,double axles and tri-axles styles under loading and unloading get close to Gauss' Distribution.Axle structure,loading and unloading of vehicle are parameters of the model.The model has advantages what disturb of vehicle style is avoided,the calculation's error which caused by the difference between theory load axle and actual load axle is avoided too,at the same time,it make investigation of traffic easy,estimation of road more well and usage in engineering convenient.
