| 1 | STUDY ON THE FINITE ELEMENT NUMERICAL SIMULATION OF SHEET METAL FORMING显示文摘Based on the Finite Element Theory of Rigid Plastic, relevant problems during plastic simulation on sheet metal forming were technologically studied and simplified; a simplified model of the blank holder during the drawing process was established and the effects of related parameters on the forming processes were also studied. At the same time, a finite-element numerical simulation program SPID was developed. The distribution of strain and relationship of stress-stroke simulated were compared with experimented, the results are well coincided with each other. It is verified that the analytical program is reliable. | J.L.Song D.J.Hu Z.L.Chang T.Y.Li Z.B.Jiang | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，3： | 2 |
| 2 | Experimental Study and Numerical Simulation of the Casting-Forging Complex Near Net Forming of Alternator Claw-pole显示文摘As a newly developed precision technology, casting-forging complex near net forming process is utilized to produce complex components with a short lead time, low cost and high precision, thus to accelerate the response speed of the market and enhance the competitive power of products. In this paper, the casting-forging complex near net forming process of alternator claw pole was developed and investigated with a combination of experimental and numerical simulation method. Qualified near net workpiece was manufactured, mechanical parameter and relative field information during the forming process was also obtained. While the alternator claw-pole is processed with this technology, the forming force is small, the process is short and the quality of forgings is perfect. Therefore, the complex casting-forging near net forming process of claw-pole is an energy and material saving technology, which will have a vast developing and application prospect in the future. | J.L.Song D.J.Hu Q.C.Wang H.Q.Chen H.G.Guo | 2004 | 上海交通大学学报2004，38，z2： | 2 |
| 3 | NUMERICAL SIMULATION STUDY ON DEFORMATION UNIFORMITY OF EQUAL CROSS SECTION LATERAL EXTRUSION显示文摘Equal cross section lateral extrusion (ECSLE) is an effective method realizing pure shear deformation. The influence of friction factor on the deformation uniformity of ECSLE was investigated with rigid plastic finite element method. The result shows that the non-uniform deformation in extrusion is caused mainly by the friction between workpiece and die. The higher the friction factor is, the more uneven plastic deformation resulted in extruded workpiece. The relation curve of deformation uniformity vs. friction factor was drawn based on the analysis result. The curve can be used as a basis of ECSLE process design. | Z.L.Chang J.L.Song N.H.Hao | 2004 | Acta Metallurgica Sinica(English Letters)2004，17，1： | 0 |
