摘要
为解决汽车门盖聚氯乙烯(PVC)在生产过程中外观质量难以控制的问题,针对PVC气泡质量基于经验定性管理的弊端,构建PVC气泡产生的自由滑动木塞密闭空间模型,结合理想气体状态方程,得到定量的PVC气泡质量状态表征公式,并从数学模型的角度分析PVC气泡的形成机理。基于数学模型和定量表征公式,客观反映门盖折边原始空腔体积、PVC烘房最高温度、PVC材料及其他环境因子对PVC气泡的影响,从而在设计和工艺方面指出质量控制方向。
It is difficult to solve the problem of exterior quality control of PVC bubbles in doors and covers in the production process.To eliminate the drawbacks in PVC bubble quality by empirical qualitative management,a free sliding wooden plug closed space model for PVC bubbles generation was constructed,and combined with the Ideal Gas Law,the quantitative formula for characterizing the quality state of PVC bubbles was attained,and the formation mechanism of PVC bubbles was analyzed from the perspective of mathematical models.Based on mathematical model and quantitative characterization formulas,the impact of factors including original cavity volume of the sheet metal fold,the highest temperature of PVC drying room,PVC materials,and other environmental factors on the positive or negative correlation and degree of influence of PVC bubbles can be objectively reflected,thereby the direction of quality control of PVC bubbles is more explicit from design and process.
