On basis of this model, the modeling methods and modeling flow were discussed based on data source of geological observation, drillhole, ichnography and section map.
Starting with the basic equation of the hydraulic system this paper deals with the mechanism modeling for double triangle boom luffer and its hydraulic system.
Based on machine kinematics and cutting theories, the simulating method for the generation of three-dimensional surfaces in face turning and flycutting of SPDT is studied.
