A method for constructing load spectra based on the distributions of road roughness and velocity was proposed to improve the authenticity and validity of the target load spectra of customer reliability. A road was divided into eight types according to GB/17031—2005, and the velocity of a vehicle was divided into n ranges. Then, the proportion of every velocity range for the eight road types to total mileage was analyzed. The load time history of per unit mileage for the eight road types with different velocities was collected, and a 100 km standard load spectrum was constructed and combined with the velocity distribution by using the rain flow counting method. The target load spectra of users were extrapolated with the total mileage of the user target. Results show that the target load spectra of customers constructed with consideration of the distributions of road roughness and velocity accurately and effectively reflect customers’ actual use conditions.
