Structural Synthesis of the Ancient Chinese Zhuge Repeating Crossbow
This work synthesizes the structure of the Zhuge repeating crossbow, invented around 220 AD and depicted confusedly in ancient Chinese literature. Based on the analysis of the mechanism, the structural characteristics and design constraints of this device with uncertain members and joints are concluded. Then, according to the concepts of generalization and specialization subject to the concluded design constraints, eight feasible structures of mechanism that meet the technological standards of the subject’s time period are systematically reconstructed.
