Computer simulation method of human-computer engineering design of vehicle cab

Abstract

The invention discloses a computer simulation method of human-computer engineering design of a vehicle cab, comprising the following steps of: firstly, establishing a human parameter database; subsequently carrying out three-dimensional operation domain analysis: inputting or calling existing human dimensions and setting the position of a manipulator to work out the sphere of activity of a human body in each plane; determining the three-dimensional operation domain of the human body by a multi-plane superposition method and judging whether the position of the manipulator is reasonable or not; if reasonable, ending the analysis; otherwise, redesigning the manipulator and carrying out the analysis again; then carrying out visual field analysis: inputting or calling existing eyellipse parameters and setting the position of an indicating instrument to work out the projected outline of the eyellipse and the projective point of the judgment point of the indicating instrument; analyzing the range of the visual field in which the judgment point of the indicating instrument is located; judging whether the position of the indicating instrument is reasonable or not; if reasonable, ending the analysis; otherwise, redetermining the position of the indicating instrument and analyzing again; and finally ending the whole design process. The invention has wide sphere of application and can improve the design efficiency.

Description

technical field [0001] The invention belongs to a computer simulation method, in particular to a computer simulation method for the ergonomic design of a vehicle cab. Background technique [0002] The vehicle cab belongs to an individual workplace, requiring the operator to operate reasonably and respond quickly. Therefore, the manipulation and control devices in the cab must be arranged in the most easy-to-operate and control position for the operator, and the ergonomic design of the vehicle cab is required. [0003] The traditional research method of ergonomics is to give the horizontal and vertical work areas through a large number of experiments, and roughly give a comfortable work area in a single plane. Although this solution method is simple, it has large errors and cannot accurately represent the actual operating range of the human body. In order to solve the human body's operating area as accurately as possible, Biman Das et al. conducted research on the horizontal...
