NIOSH 手工提举方程在缸盖搬运中的应用

摘要

To improve productivity and balance the energy and stamina of operators , human potential under the premise of safety, the NIOSH lifting equation was used to the ergonomics safety assessment on manual lift of cylin -der head in machine shop.The study on horizontal distance (H), vertical distance(V), lift distance(D)and fre-quency(F)of the operator was conducted , and the weight and height coefficients of revised NIOSH lifting equation were revised.The results showed that, after a reasonable adjustment of the four major parameters , the efficiency can be improved without robots and other equipments , simultaneously, the safety and health of the operator could be ensured.%为了平衡操作人员的精力和体力，在保证人安全的前提下，提高生产力。采用 NIOSH（Na－tional Institute of Occupational Safety and Health ）提举方程对机加工车间缸盖搬运上线工位进行人机工程安全评估，通过对操作工作业的水平距离（H）、垂直距离（V）、提升距离（D）以及频率（F）进行研究，并对修订版 NIOSH 提举方程的重量常量与高度系数进行了修正。结果表明，经过合理调整四大参数，可在不设起吊、机器人等设备的情况下，保证人的身心健康，节约成本，提高人的工作效能。
