摘　　要：为提高山地风电叶片运输的安全性,利用SolidWorks建立山地风电叶片运输车组,针对工装举升、叶片自转、工装自转3种典型工况,分析专用工装的不同定轴状态对运输车组稳定性的影响。建立装配体模型后,在一定风载荷(风速14 m/s,迎角1.571 rad)下,不断改变工装举升、叶片自转和工装自转的角度,得到车组受力及重心位置的变化规律,并分析车组重心位置随配重块位置改变的变化规律。结果表明:工装举升与叶片自转过程中车组受力分别呈M和W型变化,工装自转使车组所受横向风力减小;工装举升角度可以补偿车组在纵坡路况下的重心变化,叶片自转至180°时纵向稳定性最好,自转至190°时横向稳定性最差,自转至350°时车组受风载荷接近最大,运输工装的自转操作并不适用于常规运输工况,适用于进行避障操作或横坡路况运输;改变配重块位置可以平衡工装举升引起的整车重心位置的改变,达到车组稳定的效果。In order to improve the safety of mountain wind power blade transport,a mountain wind power blade transport vehicle group was established by using SolidWorks,and the influence of different fixed axis states of special tooling on the stability of the transport vehicle group was analyzed according to the three typical working conditions of tooling lifting,blade rotation and tooling rotation.After the assembly model was established,under a certain wind load(wind speed 14 m/s,Angle of attack 1.571 rad),the tool lifting,blade rotation and tool rotation angles were constantly changed to obtain the change law of the load force and the center of gravity position of the vehicle set,and the change law of the center of gravity position of the vehicle set with the change of the counterweight position was analyzed.The results show that the load on the vehicle group changes M and W respectively during tool lifting and blade rotation,and the lateral wind force on the vehicle group decreases due to tool rotation.The lifting Angle of the tooling can compensate the change of the center of gravity of the vehicle group under the condition of longitudinal slope road.The longitudinal stability is the best when the blade rotates to 180°,The lateral stability is the worst when the rotation is equal to 190°,and the wind load of the vehicle group is close to the maximum when therotation is equal to 350°.The rotation operation of the transport equipment is not suitable for conventional transportconditions,but for obstacle avoidance operations or cross-slope road transport.Changing the position of thecounterweight block can balance the change of the center of gravity position of the vehicle caused by thelifting of the tool,and improve the effect of the stability of the car set.
