Abstract：To improve the accuracy of delicate fruit production line for fruit grading and reduce the blindness of scan debugging, the virtual prototype simulation model was established in ADAMS software. Through the quadratic general rotary design experiments with three factors and three levels at virtual prototype, the effects of rotating actuator angle， conveyor belt speed and fruit weight on the fruit grading accuracy were discussed to obtain the regression equation of the accuracy for fruit classification.The process parameters of vulnerable fruit production line for fruit grading were obtained by the regression equation and used to conduct verification test. The results show that when the weight of fruit ranges from 236.3 to 287.7 g, the fruit grading accuracy is 86.7%.When fruit weight ranges from 247.8 to 275.2 g, the fruit grading accuracy rate reaches 100%.
