Tham khảo tài liệu 'deform-3d v6 part 6', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Figure 73 Movement controls Hydraulic controls - Average strain rate control Mechanical press The Mechanical Press type replicates the cyclic motion of a mechanical press. The parameters required to simulate the motion are the total displacement of the press Dtot relative to the current displacement Dcur and the number of strokes per unit of time S . Using these parameters DEFORM can compute the die speed at any point of the travel of the die. The movement direction can only be specified in the X Y Z -X -Y or -Z directions. The equation to derive the die speed is V 2pS D i l The parameters required to specify the movement of a mechanical press are 126 Object 1 Top-Die cã SI H Bl Name Figure 74 The mechanical press settings window 1. Total stroke The total stroke for the mechanical press represents the total travel of the die from its top position to its lowest position. In English units this is inch in SI units this is mm. 2. Strokes per second The Strokes per seconds represents the frequency of the press blows. This is a measure of blows per second or cycles per second. 3. Forging Stroke This value is total remaining distance of the die in the given stroke. This value will depend on the current position of the moving die relative to the stationary die. 4. Direction Direction is used to designate a direction in which the object s stroke will be applied. 5. Connecting-Rod Length As seen in Figure 75 the connecting rod length can have an influence on the speed of the ram. If the length of the connecting rod is known it can be input as a field. If it is not known it can left as zero and its contribution to the ram speed will not be considered. 127 Object 1 Top-Diế General Geometry s Mesh w Movement h Bdry. Cnd.
