摘要
以具有对数螺旋线型面特征的综合式液力变矩器单向联轴器为研究对象,为考察其在瞬态楔紧过程中内外环及滚子等各部分应力分布状态特性,基于显式动力学理论进行了二维平面应变和三维有限元动力学分析,分别从二维和三维的角度对这一动态过程进行了数值模拟。对2种方法仿真结果的对比分析表明,三维分析的结果所获得的各部件轴向的应力分布信息弥补了二维分析的不足,同时也验证了将实际三维单向联轴器传动过程进行二维平面问题简化的可行性,2种分析结果的一致性为单向联轴器的设计和计算提供了更为可靠的理论依据。
For one-way clutch of integrated hydrodynamic torque converter with logarithmic spiral mold surface,the stress distribution of roller,internal and external ring in the transient wedge-caulking process was investigated.Based on explicit dynamics,two-dimension planar strain and three-dimension finite element analyses were carried out,and this transient process was investigated numerically from the viewpoint of two-dimension and three-dimension respectively.Simulation results show that,compared with the planar strain analysis,the three-dimension analysis can provide axial stress distribution of each part,and the simplification from three-dimension to two-dimension analysis is feasible,and the consistency of calculation results derived from two analysis methods provides more reliable theoretical foundation for the design and calculation of one-way clutch.
