Analysis and Modeling of Human Impedance Properties for Designing a Human-Machine Control System

A human can control dynamic properties of his/her own body naturally and effectively according to tasks by utilizing the perceived information of environmental characteristics. If dynamic properties of human movements depending on environmental characteristics can be described quantitatively, there would be expected to design and develop a novel human-machine system in which an operator can manipulate more comfortably. This paper discusses a design methodology of human-machine systems integrating human motor characteristics. A vehicle interface system manipulated by the foot is focused on, and mechanical impedance properties of human lower extremities during maintained leg posture are investigated according to the leg posture and the foot force

Vibration Analysis Of Automotive Bodies Using Continuous Wave Laser Holographic Interferometry

Vibration modes from 30 Hz to 1 kHz were measured in full equipped automotive body, door, roof and windshield in a rock cave laboratory using continuous wave laser holographic interferometry and analyzed to reduce noise and vibration.
