为了提高研磨喷射装置的稳定性，在研究强化研磨系统工作原理和装置结构的基础上，通过5-why分析法推断出该装置左右移动时产生振动的原因，并结合实际情况建立了导杆受力模型。此外，通过Matlab计算出优化设计前导杆挠度的最大值，验证了因导杆弯曲变形过大而使螺杆受力的推论，并根据导杆最大挠度与横截面直径关系来确定导杆的最优直径。

In order to improve the stability of abrasive injection device when it moves left and right,the cause of vibration,based on researches on working principle of reinforced grinding system and structure of abrasive injection device,is deduced through the method of 5-why analysis. Besides,the force model of guide rod is established combined with the actual. In addition,the maximum deflection of guide rod in original design is calculated by Matlab and consequently the inference,screw bears force because of the excessive bending de-formation of guide rod,is verified. The optimal diameter of guide rod is determined by the relationship be-tween maximum deflection and cross sectional diameter of guide rod.
