Abstract：

Multi-station high speed forging technology is a kind of advanced forging technology. It has been widely used in many developed country. By this technique, the production efficiency can be raised and the production cost can be reduced. Two processes to produce the upper spring seat of diesel engine by high speed forging were simulated by Deform-2D.After that, the distribution of stress, the forging load，the distortion and the distribution of damage were analyzed and compared. The optimization objective requires that not only the load of each step shall be low and uniformly distributed, but also the upper spring seat of diesel engine produced has high surface quality and no crack. And the second method performed better. Experiments show that the upper spring seat of diesel engine produced by the second method is complete and flawless. So the second method is the better one to use multi-station high speed forging technology.
