Finite Element Analysis of Turning-milling Combined Machine Tool Based on Multi-body Dynamics Modeling
This paper takes QT200-MY turning-milling combined machine tool as object to establish the 3-D model and obtain the characteristic parameters of each structural component,derive the kinetic equations of individual structural components,and have the energy values of all the sub-structures of the machine tool substituted into the Lagrange equation to obtain the dynamics theoretical equations of the multi-body system of the whole machine tool,and to have the parameters of the relevant characteristics obtained by solving the equations. Finite element simulation is applied to verify the accuracy of the theoretical model and thus improve modeling accuracy of the turning-milling combined machine tool.
