Analysis teh effects of spin characteristics due on center of gravity changes in indeoendent suspensioned public buses

As a result of the increase in security of active drive on motor vehicles, one of the most important subject which is investigating in recently years is breaking system. Performance of breakes depends on many of parameters. As linear and lateral gradient. Distribution of vehicle load/ weight basicly determines excensive spinning, few spinning & neutral characteristic. In this study, mathematical model is developed for positions of different of passengers, number of passengers and the location of the planned inventory which will be placed on the bus. In this scientific research, MSC. Adams/car software programme is used. Different passenger positioning, and after loading, breaking action in 100 meter radius bend is analyzed. In addition, according to location to the gravity center of vehicle, some of the vehicles went off road in breaking action. In order to prevent this went of road action, desing of passengers, location of seats, and materials that will be assembledon vehicle must be considered. Due to tive distriction of gravity center, vehicle is identifred as stable in neutral spinning characteristic. In the situation of locating gravity centers of forth of vehicle, by excessive breaking action, went off vehicles from road is observe.
