Reliability prediction of no-till planter based on quality function deployment
摘要
Abstract
To address the scarcity of reliability data and the neglect of customer requirements in traditional prediction methods for no-till planters,this paper proposes a reliability prediction method based on Quality Function Deployment(QFD),with a case study on the 2BMFJ no-till precision soybean planter for wheat stubble fields.By constructing a three-level correlation matrix linking"Customer requirements"to"Technical characteristics"and then to"Subsystems",ten categories of customer requirements(encompassing failure prevention and operation quality)were transformed into seven quantifiable technical indicators,including criticality,technology maturity,and environmental harshness.An auto-correlation matrix was utilized to adjust the indicator weights,and a reliability prediction scoring matrix was developed to calculate the subsystem failure rates hierarchically.The results indicate a comprehensive machine reliability of 98.69%.The transmission subsystem(failure rate 0.533 3%)and the straw cleaning and mulching subsystem(failure rate 0.463 6%)were identified as weak links due to issues such as straw entanglement and high-load clogging.This method effectively overcomes the limitations of traditional models in terms of data scarcity and disconnection from user needs,providing a basis for the reliability design and optimization of critical components in no-till planters.关键词
