摘要
根据JJF 1059.1-2012《测量不确定度评定与表示》技术规范对检测数据的要求,为保证冲击频率检测数据的准确性和严谨性,通过对液压凿岩机冲击频率测量原理的分析,建立测量冲击频率的数学模型,确定检测过程中不确定度来源,进行分量标准不确定度、合成以及扩展标准不确定度评定,为准确评价冲击频率检测结果提供科学的方法。
According to the requirements of the technical specification JJF1059.1-2012《Evaluation and Expression of Uncertainty in Measurement》for testing data,in order to ensure the accuracy and preciseness of the impact frequency testing data,by analyzing the measuring principle of impact frequency of hydraulic rock drill,establishing a mathematical model for measuring impact frequency,determining the source of uncertainty during testing,evaluating the component standard uncertainty,combined standard uncertainty and expanded standard uncertainty.It provides a scientific method for accurate evaluation of impact frequency test results.
