Simulation and test device for complex working condition of wind turbine planet gear

Abstract

The invention relates to a simulation and test device for the complex working condition of a wind turbine planet gear, and belongs to the field of mechanical design and mechanical dynamics. The simulation and test device comprises a flat base, a motor controller, a servo motor, two diaphragm couplings, an eddy current sensor assembly, a signal collector, an acceleration sensor assembly, a magnetic powder brake controller, a magnetic powder brake and a vibration table. A motor output shaft is connected with a to-be-simulated planet gear input shaft through the first diaphragm coupling, and a planet gear output shaft is connected with the magnetic powder brake through the second diaphragm coupling. All the parts are fixed to the flat base. The signal collector is connected with the electric eddy sensor assembly and the acceleration sensor assembly through signal lines. The electric eddy sensor assembly is arranged on an input shaft test plane and an output shaft test plane, and the acceleration sensor assembly is arranged on a planet gear box test plane. The simulation and test device is simple in structure and high in simulation accuracy of the complex working condition of the wind turbine planet gear.

Description

technical field [0001] The invention belongs to the field of mechanical design and mechanical dynamics, and in particular relates to the structural design of a simulation and testing device for complex working conditions of a wind turbine planetary gear. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, my country's demand for clean energy is very urgent. Wind power generation has gained widespread attention due to its technical reliability, improvement of wind power product quality and cost advantages, and it has developed rapidly in recent years. By the end of 2014, my country's wind power installed capacity will exceed 90 million kilowatts, and the annual power generation will reach 175 billion kwh. [0003] The wind turbine gearbox is located between the impeller and the generator. It is a key component of the horizontal axis wind turbine. It transmits the power generated by the rotation of the impeller by the wind to...

Problems solved by technology

Due to complex working conditions such as speed and torque changes, displacement excitation caused by tower bending vibration, the vibration and noise problems of planetary gears have not been well resolved. Planetary gear failures are one of the main failures of wind turbine gearboxes.
