对西安石棉厂五个车间、十个岗位工种、25个工人的40个动作,通过能消耗量、心率绝对值、心率增值和心率增值百分比测定,进行劳动强度分级标准和相互关系的研究。结果表明,心率增值较心率增值百分比、心率绝对值作为以能消耗量为依据的单项体力劳动强度分级标准更为理想,值得进一步探讨。
40 workstations in five factories, ten job types and 25 workers in Xi’an asbestos factory were conducted to study the grading standards and correlation of labor intensity through energy consumption, absolute value of heart rate, percentage of heart rate and percentage of heart rate. The results showed that the value of heart rate increment, the percentage of absolute value of heart rate, absolute value of heart rate as the standard of individual physical labor intensity based on the energy consumption is more ideal and worth further study.
