项目摘要

The goal of this proposal is the development of human factors approaches to the design of tools and non-invasive treatments for repetitive strain injuries. The first research objective will use my new 6 DOF heavy mobile equipment simulator (funded using NSERC RTI 1 and Accelerator grants) housed in my newly expanded motion capture laboratory. The simulator makes use of our extensive library of field based vibration profiles to drive a hexapod robotic platform while an operator manipulates joystick controllers. We have published widely in this area and have amassed one of the most diverse catalogs in the world of off-road 6 DOF vehicle vibration field profiles. In order to best mimic actual working conditions, the simulator incorporates visual as well as haptic feedback such as would be seen and felt in an operating piece of heavy, mobile machinery. Accelerator funds were also used to purchase a pair of haptic controls coupled with a virtual reality head mount display and eye tracking as was software which allows us to create virtual environments. The simulator facility allows us to simultaneously investigate combinations of biomechanical, physiological, and psychophysical basic and applied research questions under realistic operating conditions. The first project to be pursued in this proposal will be the development and dynamic validation of a spatial 5-bar model of a joystick and operator’s upper limb. Once the model is developed, it will be validated using the simulator to assess how well it can predict the kinematic and kinetic variables for the operator’s arm and joystick. In the available literature, to my knowledge, no other research group in the world has suggested the development of a human-joystick linkage model to virtually design a joystick. These joystick design protocols could lead to design and assessment software for industrial use thus helping industry to minimize the number of prototypes that need to be built. The second project will log location and speed (via GPS) as well as rotational and translational accelerations from a working vehicle chassis in order to collect field data for an off road mobile machine such as a forestry skidder. GPS position data will then be combined with satellite images to be used with Geographic Information Software. The processed information including the vibration data will then be merged and implemented using previously developed vibration modeling techniques on the heavy equipment simulator to create location specific interactive virtual reality simulations. This will allow new devices such as joysticks, armrests and heavy equipment seats to be tested in the lab to ensure that they will work effectively when they are installed in working heavy equipment that will be used in specific locations and terrains. The second research objective involves the development of increasingly more realistic finite element models of the hand and wrist with the ultimate goal of being able to virtually predict internal wrist stress and strain in order virtually assess tools before they are built as well as to design non-surgical treatments for things such as carpal tunnel syndrome (CTS). One project will create linear elastic FE models for two wrist postures in order to quantify carpal tunnel volume and stresses in the transverse carpal ligament. The next project will expand upon this by including more soft tissue components such as nerves, muscles, tendons, fat and skin. CTS splints will also be designed virtually and evaluated through these FE models to establish which splints result in the lowest TCL stress and largest carpal tunnel volume thus helping to guide non-invasive splinting treatment methods for CTS. The final project will develop viscoelastic FE models of the hand and wrist.
这项提议的目标是开发人的因素,设计工具和非侵入性治疗反复劳损的方法。第一个研究目标将使用我的新的6自由度重型移动设备模拟器(由NSERC RTI 1和加速器拨款资助),它位于我新扩建的运动捕捉实验室中。该模拟器利用我们丰富的现场振动模型库来驱动六足机器人平台,同时操作员操纵操纵杆控制器。我们在这一领域广泛出版,并积累了世界上最多样化的越野六自由度车辆振动场分布目录之一。为了最好地模拟实际工作条件,模拟器结合了视觉和触觉反馈,例如在重型移动机械的操作部件中可以看到和感觉到的反馈。加速器的资金还被用来购买了一对触觉控制器,以及一个虚拟现实头盔显示器和眼睛跟踪,以及允许我们创建虚拟环境的软件。模拟器设施允许我们在实际操作条件下同时研究生物力学、生理学和心理物理学基础和应用研究问题的组合。该提案中要进行的第一个项目将是开发和动态验证操纵杆和操作者上肢的空间5杆模型。一旦开发了模型,将使用模拟器进行验证,以评估它对操作员手臂和操纵杆的运动学和运动学变量的预测能力。在现有的文献中,据我所知,世界上没有其他研究小组建议开发一种人-操纵杆连接模型来虚拟地设计操纵杆。这些操纵杆设计协议可以产生用于工业用途的设计和评估软件,从而帮助工业将需要建造的原型数量降至最低。第二个项目将记录位置和速度(通过全球定位系统)以及工作车辆底盘的旋转和平移加速,以便为森林集材机等越野移动机械收集现场数据。然后,全球定位系统的位置数据将与卫星图像结合在一起,供地理信息软件使用。然后,将在重型设备模拟器上使用先前开发的振动建模技术合并和实施包括振动数据的处理后的信息,以创建特定位置的交互式虚拟现实模拟。这将允许在实验室测试操纵杆、扶手和重型设备座椅等新设备,以确保当它们安装在将在特定地点和地形使用的工作重型设备上时,它们将有效地工作。第二个研究目标涉及开发越来越逼真的手和手腕有限元模型,最终目标是能够虚拟预测手腕内部的应力和应变,以便在工具制造之前进行虚拟评估,以及设计针对腕管综合征(CTS)等疾病的非手术治疗方法。其中一个项目将为两种手腕姿势创建线弹性有限元模型,以量化腕横韧带中的腕管体积和应力。下一个项目将在此基础上扩展,包括更多的软组织成分,如神经、肌肉、肌腱、脂肪和皮肤。CTS夹板也将通过这些有限元模型进行虚拟设计和评估,以确定哪些夹板可以产生最低的TCL应力和最大的腕管体积,从而帮助指导CTS的非侵入性夹板治疗方法。最后的项目将开发手和手腕的粘弹性有限元模型。
