Construction of multi motion analysis system and development of measurement methods for design.

到目前为止，已经从各种角度进行了大量的运动/姿势的人体工程学研究，以便对产品/环境设计的数据进行分类。然而，随着生活环境的变化，设计所需的人体特征数据的范围也发生了显著的变化。针对这种情况，既没有人的特征数据库中的物理应力进行定量分析，也没有很好地建立评估方法。门或柜的打开和关闭操作被假定为实验任务。特别是在牵拉练习中，研究了姿势与身体操作部位之间的因果关系。实验采用光电三维运动捕捉系统、测力板和肌电图仪。结果，已经证明身体平衡和身体机能的压力差异对运动员的健康有很大的影响。 关于我们 在牵拉运动中，下肢的应力随姿势、操作负荷和操作部位的不同而不同。此外，工作条件和身体压力的关系被认为与年龄和性别的差异。结果表明，这些差异的影响，工作高度。本研究的目的是建立一个基于这些人体数据的评估方法。随着年龄的增长，姿势变化的特点是增加胸部曲线，如圆背。圆背站立姿势由于脊柱活动性差，重心向后，需要较多的背部肌肉和腿部肌肉的力量。圆背型老年人不仅由于年龄增长导致足部肌肉无力，而且由于足部功能不全，使其难以进行姿势控制。我们认为，由于地板的柔软性和地板的微小滑动，很容易发生姿势摇摆。由于这些事实，他们往往会跌倒，并可能有严重的伤害。我们认为，圆背使姿势控制困难。少

So far, a large number of ergonomic studies on movement/posture have been carried out from various points of view in order to classify data for a product/environment design. However, the scope of the human characteristics data needed for the design has changed remarkably with the change of living environment. For such a situation, neither human characteristics database in which physical stress is analysed quantitatively, nor the evaluation method is well established.In this study, data on working posture were analysed based on a dynamic view. The opening-and-closing operation of a door or cabinet was assumed as a task for experiment. Especially about the pulling exercise, a causal relationship between posture and the operating part of the body were studied. An opto-electronic 3D motion capture system, a force plate and an electromyogram were employed for the experiment. As a result, it has turned out that body balance and stress difference by physical functions have a large influence o … More n pulling exercises, and that stress on lower extremities differs with posture, operation load and operating region. Also, the relationship between working condition and physical stress was considered with age and sex differences. It is shown that these differences are influenced by working height. This study is aimed to establish an evaluation method based on these human data.The characteristic of postural change with aging is to increase thoracic curve such as round back. Standing posture in round back needs much strength of the back muscles and leg muscles, because spinal mobility is poorly and center of gravity exists backward. It is difficult to perform postural control for the elderly in round back, because of not only muscular weakness of foot with aging but insufficiency of foot. We think that it is easy to occur postural sway by softness of floor and tiny slip of floor. As a result of these facts they tend to fall and may have a serious injury. We suggest that round back makes posture control difficult. Less
