摘要： 以6061铝合金为研究对象,建立预测机械锤击力对工件表面形变的数学模型.对该模型进行LS-Dyna有限元分析,并搭建工业机器人和音圈电机组成的机械锤击装置,探究锤击力对工件表面形变和硬度的影响,进而验证和修正理论模型.结果表明:工件表面形变随锤击力增加而增大,有限元仿真结果与数学模型的预测结果较为相近,平均误差为9.05%;进一步通过对单点锤击实验结果分析得到锤击模型的修正系数为0.7.同时锤击力越大,表面硬度也越高,锤击力为69 N时,工件表面硬度提升90.45%.

Abstract: A mathematical model for predicting the mechanical hammering force on the surface deformation of a workpiece was developed using 6061 aluminum alloy as the research object. LS-Dyna finite element analysis was performed on the model, and a mechanical hammering device consisting of an industrial robot and a voice coil motor was built to investigate the effect of hammering force on the surface deformation and hardness of the workpiece, and then the theoretical model was verified and modified. The results showed that the surface deformation of the workpiece increases with the increase of hammering force, and the FEM simulation results are similar to the prediction results of the mathematical model with an average error of 9.05%; further analysis of the experimental results of single-point hammering shows that the correction coefficient of the hammering model is 0.7. Meanwhile, the surface hardness is the higher when the hammering force is the larger, and the surface hardness of the workpiece increases by 90.45% when the hammering force is 69 N.

Key words: mechanical hammering, hammering modeling, LS-Dyna analysis, surface hardness
