目的
2
针对大型风电圆锥滚子轴承接触载荷难以直接测量的问题,以某型号风力发电机的主轴轴承为例,对轴承的滚子进行智能化改造。
方法
2
首先,将载荷传感器以及其余电路部分安装到空心滚子中,设计出用于测量接触载荷的智能滚子,并设计了相应的载荷传感器。其次,通过有限元仿真得出载荷传感器中金属圆片的径向应变分布规律,并进行了虚拟组桥的仿真分析;最后,通过试验验证了金属圆片径向应变分布的规律,并进行了传感器标定试验。
结果
2
结果表明,滚子在受到固定载荷时,所设计的组桥方式可以很好地消除滚子自转角度对载荷测量的影响,使滚子在自转时仍能输出稳定的电压。所提测量方法为得到大型圆锥滚子轴承的接触载荷提供了一种新路径。
Objective
2
In response to the challenge of directly measuring the contact load of large wind turbine tapered roller bearings
the main shaft bearing of a specific model wind turbine as an example to implement intelligent modifications on the rollers of the bearing is took.
Methods
2
Firstly
a load sensor and its associated circuitry were installed within a hollow roller to develop an intelligent roller designed for measuring contact load
along with corresponding load sensors. Secondly
finite element simulations were conducted to derive the radial strain distribution pattern of the metallic disc within the load sensor
followed by virtual bridge assembly simulations. Finally
experimental validation was performed to confirm the radial strain distribution pattern of the metallic disc and sensor calibration experiments were conducted.
Results
2
The findings indicate that when subjected to fixed loads
the proposed bridge assembly method effectively mitigates the influence of roller rotation angle on load measurement
allowing for stable voltage output during roller rotation. The proposed measurement methodology provides a novel approach for obtaining contact loads in large tapered roller bearings.
