Thin walled and high rib components (TWHRC) are widely used for rocket cabins, aircraft wings, panels and frames in aerospace equipment as critical load bearing structures. This paper is aimed to develop a novel multi-DOF envelope forming machine (MEFM) with parallel kinematic mechanism (PKM) to realize efficient manufacturing of TWHRC with high performance. Since the heavy load MEFM with PKM has many total differences with the light load PKM, such as dynamic error and precision control, this paper conducts research on dynamic error prediction modelling and precision control method for this novel heavy load MEFM.

新型重载多自由度包络成型机的动态误差预测和连杆应变反馈控制


薄壁高肋构件（TWHRC）作为关键承载结构广泛应用于航空航天设备中的火箭舱、飞机机翼、面板和框架。本文旨在开发一种具有并联运动机构（PKM）的新型多自由度包络成型机（MEFM），以实现高性能TWHRC的高效制造。由于带PKM的重载MEFM与轻载PKM在动态误差和精度控制等方面存在很大差异，因此本文对这种新型重载MEFM的动态误差预测建模和精度控制方法进行了研究。
