摘要
坐位作业容易引起腰部慢性肌肉骨骼损伤，但对其产生原因缺少分析方法。本研究结合我国人体高度和姿势特点建立了坐位作业腰部受力分析的生物力学模型，运用生物力学模型对坐位作业工人进行了分析，结果显示腰部受力与躯干角大小关系密切，躯干角小则腰部受力小，躯干角与腰背部损伤有关，说明工作中姿势负荷是引起腰部损伤的一个原因。坐位作业时腰部保持相对直立的姿势有利于作业人员健康。
hronic musculoskeletal
injury is a common disorder of sitting work. Now there is no good method for me-chanical
analysis of the disorder. A biomechanics model of sitting posture was established in this study
for analysisof the force on waist. The model collcerned the body size and posture variables。
Analysis of sitting worker by us-ing the biomechanics model showed that there was strong
relationship between force on waist and trunk angle。Thesmaller the trunk angle the less the
force on waist. Trunk angle was related to the injury of waist.It indicated thatposture load was
one of the important reason of waist injury。To keep straight posture during work is benefit
tothe health of workers。
