The selection of fracture splitting forceparameter mainly depends on experience and no theory can abide by.In this paper aim at the technique of fracture splitting of engine connectingrod, the materials fitting to fracture splitting have been analysed, according tosome influence factors that the former has researched. The influence that thechemistry compositions to the mechanics function and the physical function insteel have been analyzed. The theory of quasistatic fracture splitting of suitableconnecting rod for engine EA827 has been studied. Aimed at the new materialC70S6, the quasistatic procedure has been numerical simulation analyzed bySPH non-mesh method. The solved stress intensity factor module andparameterize model building module have been developed based ANSYS byAPDL.

本论文主要研究发动机连杆裂解工艺，根据已知的一些连杆裂解影响因素，对适合裂解的连杆材料进行了综合分析，分析了钢中各组成化学成分对力学性能和物理性能的影响，针对新型裂解连杆材料C70S6钢，对捷达EA827发动机配套连杆进行了准静态裂解理论分析，并且利用SPH无网格方法对此进行了数值模拟分析，利用APDL开发了基于ANSYS的求解连杆裂解应力强度因子模块和参数化建模模块。
