For the need of reference data in the process of a new car model development, the vehicle structure fatigue loading spectrum acquisition and analysis technique with customer correlation was used, so four-wheel six-component sensors, acceleration sensors and strain sensors were used to collect the loading spectrum in Hainan testing ground and surrounding road. Then, the statistical analysis of the part of the left and right rear wheels six-component signal in time domain, frequency domain, and rain basin were presented, respectively. The results showed that the statistical properties of maximum and the pseudo-damage value of left rear axle head were similar to the right one in the same directions. The natural frequencics of rear suspension and tire were about 1.6 Hz and 12 Hz respectively, and the pseudo- damage of structure fatigue due to vertical force was 0.000 565.
