【摘要】：风电机组设备重量大、叶片尺寸长,对运输道路有特殊要求,属于特种设备运输.文中针对目前国内大型山地风电场道路设计无规范可依的现状,系统调查了影响道路纵断面设计的叶片运输车辆相关指标.从满足车辆在竖曲线上缓和冲击、行驶时间不过短、叶片甩尾悬空部分不刮蹭地面和半挂车俯仰角限制4个方面,研究了竖曲线最小半径和长度指标,得出了不同约束条件下的凹形竖曲线和凸形竖曲线最小半径、长度计算模型.最后通过计算分析,给出不同设计速度和坡差范围下竖曲线最小半径和长度技术指标的推荐值.研究成果可供风机道路设计及建设参考,也可用于风机运输道路相关标准、规范的制定.
[Abstract]:Wind turbine equipment heavy weight, long blade size, transport road has special requirements, belongs to special equipment transport. In view of the fact that there is no standard for road design of large mountain wind farm in China at present, the related indexes of vane transportation vehicles which affect the design of vertical section of road are investigated systematically. In this paper, the minimum radius and length of vertical curve are studied from four aspects, such as satisfying vehicle impact on vertical curve, driving time is only short, blade tail-flick suspension part does not scratch ground and pitching angle limit of semi-trailer, the minimum radius and length of vertical curve are studied. The minimum radius and length of concave vertical curve and convex vertical curve are obtained under different constraint conditions. Finally, through calculation and analysis, the recommended values of minimum radius and length of vertical curve under different design speed and slope difference range are given. The research results can be used as a reference for the design and construction of fan roads, and also for the formulation of relevant standards and specifications for fan transportation roads.
