用于土方机械“ORK 循环测试”的操作员站声级测量程序

[中文适用范围]： “本 SAE 标准规定了在指定越野自走式作业机械的操作员站测量声级和确定时间加权声级的程序。本文件适用于以下作业机械： SAE J1116 中指定的操作站： ? 履带式装载机 ? 轮式装载机 ? 自卸车 ? 拖拉机铲运机 ? 压路机/压实机 ? 带推土机的垫脚轮式压实机 ? 挖掘机和轮式伐木归堆机 ? 平地机 ? 带推土机的履带式拖拉机 ? 带推土机的轮式拖拉机 ?反铲 ? 液压挖掘机 ? 集材机 ? 铺管机 ? 挖沟机 ? 清扫机 描述了这些机器的仪表要求和具体工作循环。用于计算操作员站的时间加权平均声级的方法指定为 Leq(5) )@ 或可选的汇率@ 在代表连续中型到重型工作的工作循环中连续操作期间。工作循环提供了一种可重复的可再现方法，以根据“码尺”统一测量工作机器。还提供了一种将操作员站的时间加权平均声级关联起来的方法，以估计操作员在部分负荷工作@监督@和休息时间下的声音暴露。 ” [外文原描述]： This SAE Standard sets forth the procedures to be used in measuring sound levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116:• Crawler Loader• Grader• Log Skidder• Wheel Loader• Crawler Tractor with Dozer• Pipelayer• Dumper• Wheel Tractor with Dozer• Trencher• Tractor Scraper• Backhoe• Sweeper• Roller/Compactor• Hydraulic Excavator• Pad Foot Wheel Compactor with Dozer• Excavator and Wheel Feller-BuncherThe instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for L eq(5) , or optional exchange rates, during continuous operation in a work cycle representing continuous medium to heavy work. The work cycles provide a repeatable reproduceable means to uniformly measure working machines against a “yard stick. A method to relate the time weighted average sound level at the operator station(s) to estimate operator sound exposure with part load work, supervision, and rest breaks is also provided.Cross Reference: ANSIS1.4,ANSIS1.40,IEC61672-1,ISO1999,ISO3411,ISO6165,J1116,J184_201408,J732,J919_201307
