A modeling method for continuous quantization of maintenance accessibility

Good accessibility is an important guarantee for maintenance operation tasks. Aiming at overcoming the deficiency that the degree of being accessible for points in space cannot be described by current indices related to accessibility and the problem that accessibility design and analysis cannot be conducted conveniently, for the first time, the paper proposes a modeling method for continuous quantization of maintenance accessibility. On the basis of the kinematic model of human body, the functions of influence on accessibility are established. A model of continuous quantization of maintenance accessibility is then constructed. Taking human arm as the research object, a corresponding model of continuous quantization of accessibility is set up and a visual simulation of accessibility of points in space is conducted by the use of the proposed method.
