| 摘 要： | 基于对二维振动系统的仿真分析研制了一种二维振动时效装置,通过振动特性检测验证了装置的可行性,并进行了二维振动法释放冷挤压孔周边应力实验。利用X射线衍射仪测量处理前后冷挤压孔周边的残余应力,通过对比发现二维振动法处理后孔边5 mm范围内应力平均消除率达到22.6%,最高可达32.2%;分析实验数据得出相位差是影响二维振动时效处理效果的最关键因素,其次是工件转速、激振时间、激振电压等。

| Abstract: | Based on the simulation analysis of two dimensional vibration system,this paper designs a two dimensional vibration aging device.Its feasibility is verified by the vibration characteristic test,and the two dimensional vibration mechod is used to carry out the stress removal experiment around the cold extrusion hole.The residual stress around the cold extrusion hole before and after the treatment is measured by X-ray diffractometer.The average stress elimination rate is 22.6%and the maximum is 32.2%within 5 mm of the hole edge,and the analysis of experimental data shows that the phase difference is the most important factor affecting the effect of two dimensional vibration aging,followed by workpiece speed,excitation time and excitation voltage. |
