摘要

针对风电机组用三排圆柱滚子轴承在单一变工况下的仿真结果存在局限性、片面性问题

建立一种服役工况下的主轴轴承刚性多体接触动力学仿真分析模型。分析了服役工况下保持架与滚子的理论速度、仿真速度以及加速度响应

探究了三排圆柱滚子轴承滚子与保持架和不同接触表面之间的接触力特性与规律。结果表明：径向滚子-内圈接触力为远端推力的5.67倍

远端推力滚子-内圈大部分接触力约2倍大于近端推力滚子与内圈的接触力

滚子在非承载区时自转速度会逐渐降低

下降程度与在非承载区运动时间成正比;推力滚子和推力保持架的转速和接触力存在着与轴向交变载荷一样的交替变化;径向保持架转速较为稳定

推力滚子在不受载时

对应的推力保持架会由内圈驱动运转

转速增加。

Abstract

To address the limitations and one-sidedness issues in unidimensional analysis of wind turbine three-row cylindrical roller bearing simulations under single-variable operating conditions

this study establishes a comprehensive rigid multibody contact dynamics simulation framework for spindle bearing systems under operational loading. A comparative analysis is conducted between models incorporating and omitting the transmission path considerations. Systematic investigations are performed on cage-roller kinematic behavior through theoretical velocity computations

simulated rotational dynamics

and acceleration response characterizations. The model is verified through rigorous verification procedures

enabling detailed examination of interfacial force characteristics between rolling elements and raceways in three-row cylindrical roller bearing configurations. Key findings demonstrate that transmission path integration significantly enhances simulation fidelity to actual service environments. Distinct load-bearing and non-load-bearing zones emerge in radial roller arrays

contrasting with the full-row load alternation pattern observed in thrust rollers. The contact force magnitude at the radial roller-inner race interface exceeds distal thrust roller interactions by 5.67 times

while distal thrust roller forces maintain approximately twice the magnitude of proximal counterparts. When the roller is in the non-load-bearing zone

its self-rotation speed gradually decreases

and the degree of decrease is directly proportional to the movement time in the non-load-bearing zone. The rotational speed and contact force of the thrust roller and thrust cage have the same alternating changes as the axial alternating load. The rotational speed of the radial cage is more stable. When the thrust roller is not under load

the corresponding thrust cage will be driven to rotate by the inner ring

and the rotational speed will increase.
