The essay narrates briefly the traditional definition and the unreasonableness of process capability index,and the source is that the definition of shift coefficient has defect.
本文简述工序能力指数的传统定义及其不合理性,其根源是偏移系数的定义有缺陷。
Comparing different cases by calculating, we know how the round hole variation due to strain concentration affects maximum strain point shift coefficient and maximum mean strain point shift coefficient.
本文通过力学模型的建立,运用计算机对弯曲梁式传感器应变集中区域内的应变分布的规律进行探讨,通过不同案例的计算比较,获知产生应变集中区的圆孔尺寸变化对该传感器最大应变点偏移系数和最大平均应变点偏移系数的影响的大小。
