Workers' can be exposed to high levels of hand vibration when drilling into concrete or rock using hammer drills; exposures that can cause hand arm vibration syndrome. Exposure levels may be reduced by different drill and bit designs and drilling methods, but these interventions have not been systematically evaluated. The purpose of this project was to develop a robotic test bench system for measuring handle vibration on drills in order to compare differences in drill designs, power sources, bit designs and drilling methods. The test bench is a departure from the ISO method for measuring drill handle vibration (ISO 28927-10), which requires drilling by humans. The test bench system was designed to repeatedly drill into concrete blocks under force control while productivity and handle vibration were measured. Handle vibration levels with different drills and bit sizes were similar to those collected following ISO methods. A new robotic test bench system for measuring handle vibration is presented and validated against ISO methods and demonstrates dynamic properties similar to human drilling.
使用锤钻在混凝土或岩石上钻孔时,工人可能会暴露于高水平的手部振动中;这种暴露可能会导致手臂振动综合征。不同的钻头设计和钻孔方法可以降低暴露水平,但这些干预措施尚未得到系统评估。本项目的目的是开发一种用于测量钻头手柄振动的机器人测试台系统,以比较钻头设计、动力源、钻头设计和钻孔方法的差异。该测试台与测量钻头手柄振动的ISO方法(ISO 28927-10)不同,后者需要人工钻孔。测试台系统设计为在力控制下反复钻入混凝土块,同时测量生产率和手柄振动。不同钻头和钻头尺寸的手柄振动水平与按照ISO方法收集的水平相似。本文介绍了一种用于测量手柄振动的新型机器人测试台系统,并根据ISO方法进行了验证,证明其动态特性与人工钻孔相似。
