自走式青贮收获机噪声实验室间比对结果分析

Results Analysis of Self-propelled Silage Harvester Noise Comparison among Different Laboratories

噪声是收获机械检测的重要参数之一。为了提高自走式青贮收获机检测实验室出具报告数据的可靠性,维持系统实验室检测水平,组织开展了实验室间的比对活动。采用稳健Z比分数法通过EXCEL建立数据处理模板对结果进行了分析,结果显示,参与此次比对活动实验室出具的结果均为"满意"。

Noise is one of the important parameters of harvester test. In order to improve the reliability of test report data among laboratories, maintain the level of laboratory test, and carry out comparison activities among laboratories, the results were analyzed by using robust Z ratio method to establish data processing model based on EXCEL. According to the results analysis, all the laboratories comparison results were satisfactory. The results showed that the level of laboratories was basically consistent with the laboratory level.
