Takes advantage of this provides drives the personnel and the passenger under the different state of roads, can maintain good while the place comfortableness and the security, has been the goal which the people pursue. Regarding automobile''s vibration, may divide into on the path undulation and chassis''s origin generally, but affects the biggest vibration comes from the vibration which the path causes, its transfer mode, by way of the tire, the suspension system, the seat cushion elastic damping part arrives at the human body again, the human body appraises comfortableness again based on the vibration response. The vehicles travel undulating quantity makes the comparative analysis affiliation, also provides for is engaged in the automobile to be related the personnel and the social populace makes the reference. This research take the SAAB 9000 of vehicle types as the experiment vehicle, the use infrared range finder erects vehicle of side in the SAAB 9000 vehicle type, records the vehicles in the travel to vibrate bending down, discusses the vehicles from the practice stratification plane, after the different pressure, the state of roads, the travel time fills the nitrogen and the common air, performance of data the change and compares the vibration analysis in the travel, this research analyzes difference of reason from the nitrogen tire and the general compressed air tire. Fills the nitrogen and the common air obviously after this research, the backfill nitrogen vibration obviously small which comes compared to the backfill air, thus it may be known fills the nitrogen the tire to improve the tire absorption vibration ability, reduces vehicles'' vibration therefore to lengthen the vehicles to shock proof effect and the life the system.
