The Ergonomics Research of the Joystick in Excavator Cab

Abstract

The ergonomics research of the joystick in excavator cab is a problem which requires immediately solution in our country. In this paper, we come to a conclusion that the improved cab takes shorter time and less muscle activity than the previous cab which means that the improved cab have advantage to the previous one in comfort and work efficiency.

Optimization of key position parameters for tractor steering wheel based on a driver's arm muscle load analysis

“…Feyzi et al [4] calculated the minimum permissible driving force of the pedal by measuring the muscular force of the foot on the pedal and pushing/pulling of the joystick, and obtained an ergonomically optimal design based on the physical characteristics, which could reduce the fatigue of the tractor driver to certain extent. Qin et al [5] established a comprehensive evaluation index system for tractor pedal comfort based on sitting and handling comfort, and determined the comfort range and optimum levels of pedal position parameters through single-factor test; on this basis, they analyzed the mechanism for the influence of position parameters on pedal comfort, and optimized and verified the pedal position parameters. Jin et al [6] successfully improved the comfort and efficiency of the joystick by optimizing its position parameters based on the theoretical ergonomics.…”

Progressive Co-adaptation in Human-Machine Interaction

“…An interface for teleoperation is made up of several "layers", each one with parameters that need to be modified over time for the co-adaptation to take place, even at the hardware level (Jin et al, 2014). Operation performance depends not only on the mapping between slave DoFs and operator's DoFs (DoFs of the hands and/or arms involved in the remote operation), but also on several other geometric and control parameters, such as control gain (Huysmans et al, 2006) and stiffness (Oliver et al, 2006).…”
