研究了射流抛光材料去除面形不呈理想的对称形和重复抛光材料去除量的波动不稳性,分析认为射流抛光过程稳定性和误差因素会影响材料去除的不稳定性。分析了射流系统的误差影响因素,其主要由压力波动、磨粒沉降作用和流体的紊动作用等部分组成,并研究了各误差影响因素的产生机理和对材料去除的影响。通过仿真和实验分析,得到压力波动、磨粒沉降作用和流体紊动作用的波动范围,构建了基于各误差的材料去除稳定性的完整表达式,理论计算误差范围与实验误差范围吻合。 The unsymmetrical profile of the jet polishing material is not studied, and the unsteadiness of the removal of the repeated polishing material is studied. It is considered that the stability and error of the jet polishing process will affect the material removal instability. The influencing factors of jet system error are analyzed, which are mainly composed of pressure fluctuation, abrasive sedimentation and fluid turbulence. The mechanism of each error factor and its influence on material removal are also studied. Through the simulation and experimental analysis, the fluctuation range of pressure fluctuation, abrasive sedimentation and fluid turbulence are obtained, and the complete expression of material removal stability based on each error is constructed. The range of theoretical calculation error is consistent with the experimental error range.
