| 摘 要： | 选择对喷丸表面粗糙度起主要影响作用的喷丸压力、喷嘴扫描速度和靶距3个因素,各6个水平,选用直径为0.25 mm的玻璃弹丸,应用前混合水射流对2A11铝合金进行喷丸试验；采用针描法和SJ-201 Surface Roughness Tester测量喷丸表面粗糙度；基于表面粗糙度试验数据,应用多元线性回归和多项式回归分析方法建立喷丸表面粗糙度数学模型,并将模型应用于喷丸表面粗糙度预测,研究表明:多元线性回归预测模型,计算精度高、泛化能力强、预测效果好,平均相对误差为13.37％,能够满足工业生产对喷丸表面粗糙度预测精度的要求,具有较大的实用价值.

| Abstract: | The surface roughness prediction model of premixed water jet peening strengthening was established.It chooses the 2Al1 aluminum alloy as the tests materials,the glass bullet whose diameter is 0.25 mm,the peening pressure,nozzle scanning speed and the target distance which play a major role in peening surface quality,and the six levels of each prarmeter to do the premixed water jet peening experiments.The needle depiction method and SJ-201 Surface Roughness Tester were chosen to measure the surface roughness... |
