摘要:
利用前混合磨料水射流，对高、低两种燃速的HTPB推进剂开展切割试验，着重研究不同切割条件下工艺参数对切割效率的影响，进而为工艺参数优化提供理论依据。选取切割速度（v）、出口压力（p）、磨料浓度比（T）和靶距（L）4个工艺参数为主要影响因素，以最大切割深度（H）作为切割效率的衡量指标，分别通过单因素试验和正交试验进行分析，进而完成工艺参数的优化。试验结果表明，最大切割深度随切割速度的增加而减小，且单位时间内的切割面积存在最佳值；随着出口压力的增加，最大切割深度在特定范围内近似线性增加，并逐渐趋于平缓；磨料浓度比与靶距和最大切割深度均存在最佳对应关系。正交试验结果表明，切割速度对指标影响较为显著，靶距等3个工艺参数的影响相对较小。该研究可为前混合磨料水射流作为HTPB推进剂的工程化处废技术提供理论支持。
Abstract:
Cutting test was used to HTPB propellant with high and low burning rates by using the pre-mixed abrasive water jet. Influence of process parameters on cutting efficiency under different cutting conditions was studied, and theoretical basis was provided for parameter optimization. Cutting process speed (v), outlet pressure (p), abrasive concentration ratio (T) and target distance (L) were selected as the main influencing factors, and the maximum cutting depth was used as the measurement index of cutting efficiency by single factor test method to analyze the reasons for their impact separately. On this basis, orthogonal experiments were carried out to optimize the process parameters. The results show that the maximum cutting depth decreases with the increase of cutting speed, and the cutting speed per unit time exists an optimum value; the maximum cutting depth increases with the outlet pressure, and increases linearly in certain range and tends to be steady; There are preferred correlations for both abrasive concentration and target distance. The optimization results of the orthogonal test show that the cutting speed has a significant influence on the index, while target distance and other parameters were minor factors. This study provides theoretical support for the pre-mixed abrasive water jet as an engineered waste technology for HTPB propellants.
