In the past, family of elliptic gears with closed pitch curve includes gears, high-order modified and two-segment gears. On this basis, article expands their connotation unifies them into multi-segment elliptical helical gear (HOMSMEHG), puts forward expression curve. order to obtain a physical model real tooth flanks, proposed parametric design approach on HOMSMEHG based virtual shaping, including decoupling basic parameters, shaping cutter, linkage models, which had laid theoretical...
Due to the influence of uncertain external disturbance and model error, trajectory tracking manipulators has some problems such as inaccuracy, low speed severe chattering. To solve mentioned, a sliding mode control method combined fuzzy controller Radial Basis Function Neural Network (RBFNN) was proposed. The RBFNN used approximate equivalent system manipulators, weights their hidden layers were updated adaptively online. robust item with form had been set compensate disturbances or...
The condition of the drilling a roof bolter for mine support system is complex, and existing analytical approaches vibration oil wells cannot be fully applicable to it. In order reveal mechanism bolt drilling, some models longitudinal, bending, torsional coupled were established based on energy method finite element method. A global matrix was assembled in units. Taking as boundary conditions, reduced-order model constructed. simulations mudstone show that mode shape positively correlated...
