Abstract
A wind-driven generator yaw system testing stand is characterized by comprising a testing stand base, a loading cylinder base, a loading cylinder, a loading arm, a simulation tower drum, a yaw brake disc, a yaw brake assembly, yaw bearings, an original machine cabin, an anti-rotation frame and a loading disc. An original machine head is adopted. The simulation tower drum and the yaw bearings are additionally arranged. An external hydraulic station is controlled by a computer control system to generate vertical loading pressure. The loading cylinder acts on the head through a connecting plate to simulate the vertical load of the head. The anti-rotation frame restricts the rotation of the head. The head is made not to rotate during a working process while the simulation tower drum rotates. By adopting the relative movement theory, the testing stand with an innovative structure makes the head static and meanwhile makes the simulation tower drum rotate. The loading cylinder is further adopted for loading and simulating the vertical load of the head. The problem that the vertical load of a rotary head in a laboratory is unachievable is solved. The testing stand further integrates the testing of vibration, noise and friction plate wearing and the testing of a yaw motor, the yaw bearings, a lubrication system and a hydraulic system, etc. into a complete testing system. A computer is adopted for a control purpose. Experimental data and experimental curves can be acquired and processed in a timely manner and further displayed and stored. Researches on vibration, noise, the mechanical lifetime and reliability of a yaw system can be performed in a rapider and more convenient way. The performance and qualities of wind-driven generator yaw parts produced by manufactures are well documented. Furthermore, reliable technical supports for relevant departments to perform research and development and performance detection are provided.
