摘要:

提出风电机组传动链地面测试系统载荷模拟技术. 论述风电机组地面传动链测试系统,对拖动实验下叶轮的转动惯量进行计算,分析总结3种主要的非扭矩五自由度加载结构方案:对称加载方案、径向偏心加载方案与并联六液压缸加载方案,论述方案的加载原理,并构建3种方案的载荷求解方程. 为了进一步模拟风电机组六自由度的载荷,根据对称加载方案原理设计搭建100 kW风电机组传动链测试系统加载实验台,实验对非扭矩五自由度载荷进行了精确复现,验证了非扭矩五自由度加载技术的可行性与合理性,再结合对风力转矩载荷的模拟技术,实现了对风电机组六自由度载荷的完整模拟.

Abstract:

A load simulation technology for ground test system of wind turbine drive chain was proposed. The ground drive chain test system of wind turbines were discussed, and the inertiamoment of impeller under the drag test was calculated. Three main non-torque five-degree-of-freedom loading structural schemes were summarized, i.e., symmetrical loading scheme, radial eccentric loading scheme and parallel six hydraulic cylinders loading scheme. The loading principles of the schemes were discussed, and the load solving equations of the three schemes were constructed. A 100 kW wind turbine drive chain test system loading experimental bench was designed and constructed based on the principle of symmetrical loading scheme in order to further simulate the six-degree-of-freedom load of the wind turbine. The load was accurately reproduced, the feasibility and the rationality of the non-torque five-degree-of-freedom loading technology was verified, and combined with the wind torque load simulation technology, a complete simulation of the wind turbine's six-degree-of-freedom load was achieved.

Key words: wind turbine    drive chain test    six degree-of-freedom load simulation technology    non-torque five degree-of-freedom loading    drive chain loading system test bench
