摘要

利用地面试验平台对风电机组机舱传动链进行机械测试能有效模拟机组在复杂环境的受载情况

平台常用的多点多位置加载的共轭加载方式施加非扭矩五自由度载荷具有强耦合性

该文针对共轭加载式精确加载力计算与科学加载位置问题进行载荷空间解耦研究。建立共轭加载式系统结构的参数模型

并进行结构受力分析;基于加载轴静力学平衡关系

推导全耦合和无附加弯矩分量情况下加载力与非扭矩载荷的两种转化矩阵关系;得到非扭矩载荷的空间解耦公式

在此基础上进行计算和对比研究发现无附加弯矩时轴向加载力对称放置最为科学

并依此将转化矩阵缩聚为转化方阵;进一步使用条件数判据进行参数稳定性分析

给出工程应用的参数选取标准;最后根据静态和动态加载载荷算例进行空间解耦计算和校核。

Abstract

Using a test rig to conduct mechanical testing on the wind turbine drive-train can effectively simulate the loading conditions the turbine experiences in complex environments. The conjugate loading method with multi-point and multi-position loading

commonly employed in the test rig for applying non-torque 5-DOF loads

exhibits strong coupling characteristics. This paper studies the spatial decoupling of loads to address the precise loading force calculation and scientific loading position problem of the conjugate loading method. A parametric model of the conjugate loading method system is established

and structural force analysis is conducted. Based on the static equilibrium relationship of the loading axis

two conversion matrix relationships between the loading force and non-torque loads are derived under full coupling and no additional moment component conditions. The spatial decoupling formula for non-torque loads is obtained

and calculations and comparative studies reveal that symmetrical placement of axial loading forces is optimal when no additional bending moment component exists. Accordingly

the conversion matrix is condensed into a square conversion matrix. Furthermore

parameter stability analysis is performed based on the condition number criterion

and parameter selection standards for engineering applications are proposed. Finally

spatial decoupling calculations and verification are conducted through static and dynamic loading case studies.
