Abstract

Virtual prototyping develops as a new technology to replace existing physical prototypes for product evaluation, which are dear and time-consuming from design to manufacture. This paper presents a measurement-driven, musculoskeletal, full body simulation model for biomechanical analysis when the pilots are operating in the cockpit. A simulation model is implemented in the AnyBody Modeling System based on the measurement data. Digital Human Modelling (DHM) software packages such as AnyBody Modelling System, often integrate with CAD systems to provide a virtual environment which allows investigation of operator and product compatibility. This model makes it possible to optimize where the most comfortable location of the cockpit instruments is. Answers to such problems are not easily got by the traditional experiments. In this paper, a three-dimensional localization algorithm based on Particle Swarm Optimization is presented to search out the optimal location. The method finds the optimal localization results on the basis of the volume from anchor nodes to unknown nodes.
