On Motion Planning For Narrow-Clearance Assemblies Using Virtual Manikins
51ST CIRP CONFERENCE ON MANUFACTURING SYSTEMS(2018)
摘要
Digital Human Modeling (DHM) is an important tool to improve assembly ergonomics and thereby also productivity and product quality. State of-art DHM tools can simulate challenging assembly operations by solving inverse kinematic problems so that the positions/orientations of the hands/feet of a manikin match some manually-specified targets. However, it is still difficult and time-consuming for a simulation engineer to perform an assembly with narrow insertion clearances by manually setting hand targets. We present a novel and highly automated approach that explores the 4D space (position of a fingertip plus pronation/supination of the arm) around an initial path for a sphere. (C) 2018 The Authors.
