This paper deals with a manufacturing process for the muffler tube. In order to investigate and predict an optimal forming condition of the muffler tube, the finite element analysis has been carried out. The simulation results by the computational analysis were reflected to the forming process design for the muffler tube. The shape of the muffler tube for heavy equipment and the number of the tube hole has been made variously according to the weight and function of the car. A muffler is an important part used to reduce noise and to purify exhaust gas in cars and heavy equipment. Also there has been a growing interest in the design and manufacturing of the muffler tube due to the strict environment regulations. The perforating technique of the muffler tube has a great influence on the manufacturing cost. The perforating process is performed in the longitudinal direction of the tube. According to the simulation results, when the shear angle of punch was similar to the tube curvature, the optimal shape was obtained. Also when the clearance of die was 0.2㎜, the burr was minimized and optimal shear section was obtained.
