NIOSH手工提举方程在缸盖搬运中的应用

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（National 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。

Application of NIOSH lifting equation in manual lift of cylinder head

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.
