Stiffness Analysis of 4-PRP+3-UPS&PU Hybrid Machine Tool with Redundant Actuation

Stiffness Analysis of 4-PRP+3-UPS&PU Hybrid Machine Tool with Redundant Actuation

A six degree of freedom 4-PRP+3-UPS&PU redundant hybrid machine tool is proposed,and the statics and static stiffness of the machine tool is studied. Firstly,based on the force Jacobi matrix,the static equilibrium equation is presented,and the mapping matrix between the external load and the...
