Mechanical vibrations transmitted during subsoil operation may cause damage to the health of operators. Therefore, this work aimed to evaluate the occupational vibration acting on an agricultural tractor operator with attached subsoiler implement while performing the subsoiling operation in an area intended for eucalyptus planting. The technical procedures adopted were those established by Occupational Hygiene Standard 09: Assessment of Occupational Exposure to Fundacentro Full Body Vibrations. The instrument consisted of a Larson Davis model HVM 200 vibration analyzer and a Seat Pad triaxial accelerometer, which was attached to the farm tractor seat with tape. The tests were performed in two areas of terrain with varying amount of forest residue. The tests demonstrated acceleration values resulting from normalized exposure above the tolerance limit in both scenarios, indicating the need for immediate corrective action.
在地下作业过程中传递的机械振动可能会对作业人员的健康造成损害。因此，本研究旨在评估在桉树种植区域进行深土作业时，农用拖拉机操作人员所受的职业振动。所采用的技术程序为职业卫生标准09:基底全身振动的职业暴露评估。该仪器由一台Larson Davis HVM 200型振动分析仪和一个座椅垫三轴加速度计组成，用胶带固定在农用拖拉机的座椅上。试验是在两个具有不同森林残留物的地形区域进行的。测试表明，在这两种情况下，标准化暴露导致的加速度值都超过了公差限制，这表明需要立即采取纠正措施。
