Description

technical field

[0001] The invention relates to a multi-degree-of-freedom force / moment loading and load simulation system, in particular to a master-slave double-parallel twelve-degree-of-freedom generalized force-compliant loading mechanism. Background technique

[0002] The generalized loading system is used to simulate complex and changing six-dimensional generalized forces in special working environments. It can be used in space-to-ground simulation experiments, aerospace material fatigue comprehensive experiments, and load simulation experiments.

[0003] The loading and driving methods of the current loading system and load simulation system basically belong to single-degree-of-freedom electro-hydraulic drive, so only single-degree-of-freedom loading can be performed. Chinese patent: Generalized loading system based on parallel six-degree-of-freedom platform, patent number: ZL200310108997.4 Aiming at this problem, a generalized loading scheme based on parallel multi-de...
