| 摘 要： | 曲拐是大型船用发动机曲轴的重要部件。本文以6-S60MC-C组合曲轴曲拐为研究对象,以大型非线性有限元软件ANSYS为分析平台,采用大变形弹塑性有限元理论,对曲拐弯曲锻造过程作了数值模拟分析。分析了弯曲成形中出现的主要缺陷,提出了毛坯形状和尺寸、模具参数对成形质量的影响规律,为实际生产提供了理论依据。

| Abstract: | Crank is a very important component of crankshaft in large marine engine. Based on the elasto-plasticity FEM theory with large deformation and ANSYS that is a powerful FEM program, the bend forging of the crank used in 6-S60MC-C combined crankshaft are analyzed through numerical simulation. The forming defect of the bend forging and the influence of blank and die shape parameters are studied. All of these provide theoretical basis for practice. |
