液压泵空气传播噪音的台架试验

[中文适用范围]： 传达精确测量地面车辆转向系统中常用的正排量液压泵的声功率级的过程。该推荐实践定义了泵的安装（滑轮@皮带张力@隔离）@操作条件（流体@速度@温度@压力）@室内声学@仪器@噪声测量技术和要使用的数据采集设置。其中包括测试样本大小和数据演示电子报告格式的建议。PurposeRecord 是车辆制造商和泵供应商之间执行测试的常用方法。 [外文原描述]： Communicate the process of accurately measuring sound power levels of positive displacement hydraulic pumps commonly used in ground vehicle steering systems. This recommended practice defines the pump mounting (pulley, belt tension, isolation), operating conditions (fluid, speed, temperature, pressure), room acoustics, instrumentation, noise measurement technique and data acquisition setup to be used. Included are recommendations for test sample size, and format for data presentation/reporting.Cross Reference: ANSIS1.11,IEC61672-1,IEC61672-2,ISO3745
