Abstract

Based on black-box type identification method, dynamic thermal error models of shape and joint elements in giant floor type boring machines are obtained as discrete models. To derive error transfer functions (TFs) of the error elements, input and output data of the dynamic subsystems have been collected through the finite element (FE) thermal analysis. Synthesis of thermal error in the giant floor type boring machine is conducted by using the TFs and the previously developed kinematic error chain [1-2].
