In view of the shortage of productivity caused by high manual participation in the production of tuft of short fiber, an automatic surface forming control process of tuft of short fiber based on vibration method is proposed and designed. First of all, through the analysis of the tuft of short fiber forming process, the vibration forming device is designed, and the parameters that affect tuft surface the forming process are proposed, including mold surface, exciting force, time and tufts weight. Then, the surface of the tuft of short fiber was formed, and the standard features of the die surface and the surface were determined by the technical workers. Then, the surface features of the standard were quantified by the tail curvature of the tuft, and the characterization parameters were obtained. Finally, the response surface method is used to optimize the automatic forming process parameters, and the optimized automatic forming process parameters are obtained, namely, the exciting force is 6.71 kN, the time is 1 min, and the mass of the tuft of short fiber is 25.25 g, and the verification test is carried out. The results show that the vibration method can realize the automatic forming of the tuft of short fiber surface.
