Assessment of Physical Demands in Building Component Manufacturing Operations

Landmark是一家不断发展壮大的组织，致力于为客户提供最佳的建筑解决方案。这个 该公司制造的模块化房屋具有无与伦比的强度，超过了这座城市的任何其他房屋。尽管有高科技 自动化和半自动生产线上，有一些任务与手动处理有关 不同大小和重量的部件，如门框和木材。视组件而定 重量、搬运方法、动作频率以及运动员休息的次数和持续时间 对于工人来说，他们的肌肉骨骼系统可能面临与工作相关的疾病，如下腰痛(LBP)的风险。 里程碑致力于成功获取有关员工如何执行指定任务的信息，特别是 在一些往往伤害发生率较高的生产线上。大多数受伤形成了这些线条 往往是重复性劳损。 拟议的项目旨在： 1-对Landmark生产线中的高风险工作站执行物理需求分析(PDA)； 2-模拟被识别为劳动密集型工作站的工作站的任务机动 在格伦罗斯康复医院辛克鲁德运动和平衡中心的PDA，测量 反作用力和力矩，身体节段的运动学以及肌肉活动， 3-建立完整的人体模型，包括骨骼、肌肉和关节，以预测肌肉和关节的力量 对2中模拟的任务动作的反应， 4-使用人体工程学原理建议纠正操作并重新设计工作场所元素。 这项研究的结果将用于为Landmark工作站创建新的PDA，并提出 改善工人安全条件的纠正建议。

Landmark is a growing organization dedicated to providing the best building solutions to their customers. The company manufactures modular homes of unmatched strength to any others in the city. Despite of high-tech automated and semi-automated manufacturing line, there are some tasks associated with manual handling of components of different size and weight such as door frames and timbers. Depending on the components weight, handling method, frequency of maneuver, as well as the number and duration of the breaks taken by the workers, their musculoskeletal system might be at risk of work-related disorders such as Low Back Pain (LBP). Landmark is committed to succeed in gaining information on how workers perform assigned tasks particularly in some of the production lines which tend to have high rate of injury incidence. Most injuries form these lines tend to be repetitive strain injuries. The proposed project aims to: 1-Perform Physical Demand Analysis (PDA) for high risk work stations in Landmark production line, 2-Simulate the task maneuvers of workstations, which were identified as labor intensive workstation in the PDA, in the Syncrude Center for Motion and Balance at the Glenrose Rehabilitation Hospital to measure the reaction forces and moments, kinematics of body segments as well as muscle activity, 3-Develop full human body model, including bones, muscles and joints, to predict muscles and joints forces in response to task maneuvers simulated in 2, 4-Suggest corrective maneuvers and redesign workplace elements using ergonomics principals. The findings of this study will be used to create new PDAs for Landmark workstations, and to propose corrective suggestions to improve the safety conditions of workers.
