Abstract

Kinematic hand models can be used to predict where workers will place their fingers on work objects and the space required by the hand. Hand postures can be used to predict hand strength. Kinematic models also can be used to predict tissue stresses and to study work-related musculoskeletal disorders. Study and design of manual hose installation is an important application for kinematic hand models. Hoses are widely used in many mechanical systems such as autos, aircraft and home appliance, which are all mass-produced on assembly lines. Studies of automobile assembly jobs show that hose installations are one of the most physically demanding jobs that workers perform. Hoses are a good starting point for kinematic model development because they can be characterized as simple cylinders.
