Performance Optimization of Motion/Force Transmissibility of Reconfigurable Cable-Driven 3D Printers
摘要
To enhance space utilization and decrease energy consumption in reconfigurable cable-driven 3D printers, an optimization method was proposed for adjusting the base position and the driving cable tension of the mechanism. Motion/force transmissibility indeces for the reconfigurable cable-driven 3D printer mechanism were derived using screw theory, enabling the analysis of motion/force transmission performance within the mechanism's workspace. Optimization models for the system's base position and driving cable tension were developed based on these indeces. By optimizing the base position, motion/force transmissibility within the working space was enhanced, and the efficiency of driving tension utilization was increased through optimization of the cable tension range. The results of the study demonstrated that optimizing the base position could improve the system's motion/force transmission performance and reduce the overall footprint of the 3D printer system. Additionally, optimizing the driving cable tension could further enhance the driving tension utilization efficiency while maintaining good motion/force transmissibility within the printing space, leading to reduced energy consumption of the system.
