摘要: 针对磨料水射流加工碳碳复合材料的冲孔过程,结合Fluent分析高压磨料水射流的射流压力、靶距对碳碳复合材料冲孔深度的影响;利用ANSYS/Ls-dyna有限元分析软件建立磨料和水的射流冲击模型,针对射流压力是冲孔分层的的主要因素进行仿真,得出材料失效时最大的应力和整个射流过程中应力的变化规律,由最大应力所在位置的层间y向位移变化确定分层情况;根据仿真结果进行相应的试验研究,并将仿真结果与实验结果进行对比分析,验证了射流仿真模型的可行性和有效性。

Abstract: For punching process of carbon-carbon composite processed by abrasive water jet, combined with Fluent analysis of the impact of high pressure abrasive water jet pressure and target distance on carbon-carbon composite punching depth; by Using ANSYS/Ls-dyna Finite element analysis software the impact model of abrasive and water jet is established. To simulate with that the jet pressure is the main factor of punching and stratification, obtaining the maximum stress when the material loses efficacy and the change regulation of stress through the whole jet process, The stratification by the adjacent layer in the y-direction displacement changes of the position of maximum stress is defined. To conduct the corresponding experimental study according to the simulation result, the simulation results and experimental results are compared to verify the feasibility and effectiveness of the jet simulation model.
