The modeling of the gear system of wind turbine yaw system with impact was investigated. Based on dynamics of flexible multibody system theory, dynamic equations of the gear system were established. According to Newton's collision model, the dynamics model of the gear system with impact is established. Then the gear system was simulated to obtain the history of the impact force and the angular acceleration...
The electrical model and nonlinear characteristics of the silicon photovoltaic (PV) cell are analyzed in this paper. The SIMULINK simulation model is built based on the output characteristics of single PV cell. The common methods of maximum power point tracking (MPPT) are comparatively studied. An improved method based on the traditional incremental conductance method is simulated and studied. Simulation...
The location and allocation of regional distribution center is the key problem of logistics distribution network, it concerns that whether the distribution system can perform efficiently. The paper sets up a mathematic location model of generalized transportation costs on basis of economic scale, and then solves Location and Allocation Problem of regional distribution center by means of Fuzzy graph...
