| Abstract: | The vibration mathematical pattern of car main structures effected by step dry frictional function was anulysed in this paper by using probability statistical method. In addition the output mean square deviation of displacement and acceleration of the second order linear elastic force of car was presented, then some variations may be choice of properly, which will effect vibration of car. |
