| Abstract: | Owing to the high velocity required for a press slide,the main control valve has to be opened and closed frequently and rapidly. However, as the inertia of the moving parts of a press is usually rather large, serious pressure surge and mechanical vibration are even more likely to occur. To remedy such a situation,it is necessary to have a main control valve with fairly good open-close characteristic. An approach based on the modified harmonic displacement curve of slide and 2-D fluid transient coupled equations as well as the finite element method is proposed. |
