- 摘要:
- 以EP 200型织物芯输送带为研究对象，首先通过拉伸试验获得该输送带应力与应变的样本数据，然后利用QQ图对数据分布进行初步检验，再采用核密度拟合概率分布对数据进行K-S拟合和正确性验证，最后计算输送带的制程能力指数。结果表明，织物芯输送带的拉伸强度分布大致属于正态分布；核密度估计法可有效解决样本数据不足的问题，在工程上具有一定优越性；制程能力指数不能匹配产品的良品率。进一步分析全厚度拉伸强度稳定性的影响因素将有利于输送带的生产优化。
- Abstract:
- EP 200 fabric core conveyor belt as the research object, firstly the sample data of stress and strain were obtained through tensile strength test, secondly the data distribution was preliminary tested using QQ chart, and then the kernel density fitting probability distribution was used to verify the K-S fitting degree and correctness of the data, and finally the process capacity index of the fabric core conveyor belt was calculated. The results showed that the tensile strength distribution of the fabric core conveyor belt roughly followed a normal distribution, the kernel density estimation method could effectively solve the problem of insufficient sample data and had certain advantages in engineering, and the process capacity index could not match the yield rate of the product. Further analysis of the factors affecting the stability of full- thickness tensile strength would be beneficial for optimizing the production of conveyor belts.
