[0051] Such as figure 1 As shown, two coordinate systems are used when building the dynamic model of the roadheader: geographic coordinate system and fuselage coordinate system. O-xyz represents the fuselage coordinate system, and O'-x'y'z' represents the geographic coordinate system. The geographic coordinate system is usually considered an inertial coordinate system.
[0052] Such as figure 2 As shown, the hydraulic cylinders of the hydraulic propulsion system of the roadheader are evenly distributed in the shield head, and the hydraulic ...
