【摘要】：介绍了SIMPACK中柔性体文件生成流程以及齿轮切片处理原理及相关用途;以某7MW风电齿轮箱为例,在SIMPACK软件中建立其一级行星轮系多体动力学模型;建模过程中将行星架考虑为柔性体,并对齿轮作切片处理,分析行星轮系统在额定输入功率、额定转速工况下行星架变形,以及由于行星架变形造成的齿轮不均载特性。研究发现,当使用精确的行星架三维模型,并考虑行星架柔性时,受齿轮啮合力变化以及齿轮变形的影响,不同行星轮销轴两端行星架变形量不同,总体上输入端扭转变形量大于输出端;并对比行星架变形和齿轮均载系数,发现行星架扭转变形主要影响齿轮齿向不均载系数,对齿间载荷分布影响很小。研究结果可为行星架结构优化设计提供依据。
[Abstract]:This paper introduces the process of generating flexible body file in SIMPACK, the processing principle of gear slice and the related application, taking a certain 7MW wind power gearbox as an example, the multi-body dynamics model of the first-order planetary gear train is established in SIMPACK software. In the process of modeling, the planetary frame is considered as a flexible body, and the gears are sliced, and the planetary frame deformation under rated input power and rated rotational speed is analyzed. It is found that when using the accurate three-dimensional model of planetary frame and considering the flexibility of planetary frame, it is affected by the change of gear meshing force and the deformation of gear. On the whole, the torsional deformation at the input end is larger than that at the output end, and compared with the planetary frame deformation and the gear load equalization coefficient, it is found that the planetary frame torsional deformation mainly affects the gear tooth uneven load coefficient. It has little influence on the load distribution between teeth. The results can provide the basis for the optimal design of the planetary frame structure.
