Weak stiffness region identification and optimization of a high-precision heavy-duty gantry machining center based on the modal mass distribution matrix

Insufficient structural stiffness in high-precision, heavy-duty gantry machining centers can directly affect machining accuracy and operational stability. To address this issue, the identification and optimization of structurally weak-stiffness regions are investigated. A finite element model of the entire machine tool...
