Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments.

[0019] 1 Configuration method of vibration sensor for wind turbine gearbox based on structural analysis

[0020] The vibration sensor configuration and method of wind turbine gearbox for structural analysis mainly includes the following steps: 1) Analyze the structure of the gearbox system; 2) Build the dynamic model of the gearbox system; 3) Apply the structural analysis method to configure the gearbox sensor. Let's introduce them separately.

[0021] 1.1 Analyze the structure of the gearbox system

[0022] The structures commonly used in wind turbine gearboxes include one-stage planet and two-stage parallel, two-stage planet and one-stage parallel, single-stage planet (semi-direct drive), two-stage planet, and one-stage planet and one-stage parallel. First determine which structure the sensor gearbox to be configured belongs to, and then define each component of the g...

Abstract

The invention discloses a fan gearbox vibration sensor collocation method based on structural analysis. The method includes the steps: 1) analyzing a gearbox system composition structure; 2) setting a gearbox system dynamic model; 3) using a structural analysis method for gearbox sensor collocation. According to the method, mounting positions and quantity of vibration sensors are determined by an internal structure and dynamic operating characteristics of a gearbox to guarantee detection of accurate and comprehensive vibration signals, and consequently fault prediction and fault diagnosis precision of the gearbox can be improved.

Description

technical field [0001] The invention relates to a configuration method for a vibration sensor of a wind turbine gearbox based on structural analysis. Background technique [0002] According to the data from 2003 to 2009 given by the "Wind Statistical Briefing", the main components that cause the downtime of wind turbines are main bearings, gearboxes and generators, and the downtime caused by gearboxes is the longest [1], and it is also The maintenance cost is the highest in the 20-year design life. Therefore, effective gearbox condition monitoring and fault prediction are important means to avoid major gearbox failures and reduce wind turbine maintenance costs. The interior of the gearbox is mainly rotating meshing mechanical parts, so it will inevitably generate vibration during the working process, especially the vibration characteristics under fault conditions are very prominent. Therefore, it is the most direct and effective method to use the vibration monitoring signa...
