조향동작의 생체역학 분석 및 조향장치 설계 응용

This research deals with biomechanic analysis of steering motion of drivers and application to the configuration design of steering wheels. Upper body motion of a driver is obtained by motion capture of steering motion in a mockup driving seat with a steering system capable of applying external torque due to various driving environment. Combined dynamic model that includes driver's upper body muskuloskeletal system and the steering system is setup. Through inverse dynamic analysis by providing motion data obtained from motion capture and external steering torque, muscle forces in the arms are calculated. EMG and muscle forces are compared to validate the computed results, which showed good correlation. Parameter study of muscle force due to different configurations of steering wheel and driver's posture is performed in order to establish theoretical basis for biomechanic based steering wheel design.
