摘要

针对直升机无铰旋翼不旋转斜盘机构带钟式稳定杆的结构，提出了一种运动等效机构3-RUS+PU并联机构。采用逆解法对该机构进行了位置分析。利用虚拟机构法，给出了该机构的影响系数矩阵，并用微分法验证了其正确性。在考虑机构尺寸和质量的情况下，得到了机构的加速度性能指标和惯性力性能指标图谱。利用性能指标值与机构尺寸之间的变化趋势，从图集中选择性能指标较好的机构尺寸。

Dynamic performance analysis of kinematical equivalent 3-RUS+PU swashplate mechanism

A kinematical equivalent mechanism names as 3-RUS+PU paralled mechanism is proposed according to the structure of helicopter non-rotating swashplate mechanism in hingless rotor with Bell-hiller stabilizer bar. Inverse solution is used to get the position analysis of this mechanism. By virtual mechanism method, influence coefficient matrices of this mechanism are given, and the correctness is validated by differential method. With considering the size and mass of mechanism, the atlas of acceleration performance indices and inertia force performance indices are got. From the atlas, the better size with better performance indices is chosen by using the trend between the value of performance indices and the size of mechanism.
