The force analysis model ofring reducer is built. Following this, it is concluded that the present ring reducer~ have theproblem that the inertia force or the inertia moment is lopsided. On the base of analysis andcalculation the balanced ring reducer which can realize the balance of inertia force and inertiamoment is brought forward, and so is its concrete realizing step. The specimen of the balanced ringreducer is designed and manufactured; the experiment is carried out on the gear transmission testbench. Compared with other ring reducer of the same power, the balanced ring reducer has manyadvantages, such as low vibration noise, low cost and less production difficulty and less heat. Itis the substitute of other ring reducer of the same kind. Therefore, it has important theoreticsignificance and highly practical engineering value.展开更多
文摘旋转双臂的柔性结构在转动调姿时或外部扰动的影响下产生振动,将影响系统的稳定性和定位精度,减速器间隙非线性影响旋转双柔性梁结构的动态特性,加大了控制难度。研究了一种多变量非线性T-S模糊(nonlinear T-S fuzzy,简称NTS)控制算法,利用模糊控制器的多变量解耦控制能力以及T-S模糊规则具有的分段控制特点快速抑制柔性结构小幅值振动。设计并建立了交流伺服电机通过行星减速器驱动转动的双柔性压电梁结构实验平台。利用压电传感器采集振动信号,压电驱动器和交流伺服电机驱动器抑制柔性结构振动,对该控制方法进行实验研究。实验结果表明,相对于比例加微分(proportional and derivative,简称PD)控制算法,非线性T-S模糊控制算法对于系统的大幅值振动和小幅值振动都有较快速的振动抑制效果。
