Abstract: The static torque management of small batch trial production in the final assembly plant is different from that of sample car trial production, and the quality of fasteners produced in small batch will be significantly superior to that in the sample car stage. In order to standardize the static torque management in the small batch trial production stage of new models in the final assembly plant, this paper proposes to convert the static torque data accumulated during the trial assembly stage of new models by means of the mean value and standard deviation formula. The static torque standard applicable to the small batch trial production stage of the new model can be obtained, that is, the mean value of the static torque data of the sample vehicle is taken as the reference value of the static torque in the small batch trial production stage of the final assembly, and the 6 standard deviations of the mean value is taken as the tolerance. This method can quickly adjust the static torque standard of the whole vehicle to meet the demand of torque supervision for small batch trial production of new models in final assembly.
