【摘要】 针对倾转旋翼机在倾转作动器出现部分结构失效等故障时仍能保证飞机安全返回的需求，设计了一种安全双冗余倾转作动器。首先通过研究电子凸轮运动规律，设计了倾转作动器运动算法;然后对运动曲线进行五次多项式优化，TwinCat运动仿真结果显示加速度连续，消除了倾转作动器柔性冲击问题;最后通过运动准确度实验验证运动曲线优化后的精度误差小于1.5°。研究表明，五次多项式优化后的运动曲线具有较好的运动精度，能够消除机构运动柔性冲击，减小抖动，提升了整个运动过程的准确性和稳定性。更多还原

【Abstract】 A safe double-redundant tilting actuator is designed to meet the requirement of ensuring the safe return of the aircraft in various fault conditions such as partial structural failure of the tilting actuator for tiltrotor aircraft. The motion law of electronic cam is studied,and the motion algorithm of tilting actuator is designed.The motion curve is optimized by fifth-order polynomial optimization,and the acceleration is continuous according to TwinCat motion simulation results,which eliminates the problem of flexible impact of tilting actuator. The accuracy experiment shows that the precision error after optimizing the motion curve is maintained and the precision error is less than 1. 5 degrees. The polynomial movement curve has good motion accuracy,can eliminate the flexible impact of mechanism movement,reduce jitter,and improve the accuracy and stability of the entire movement process.更多还原
