The study of fixture stiffness – Part II: contact stiffness identification between fixture components

This paper describes an experimental investigation to estimate the contact stiffness in normal and tangential directions. The static method was used to estimate normal contact stiffness and to study the effecting factors. In order to study tangential contact stiffness, dynamic methods were developed to estimate contact stiffness in both normal and tangential directions. That study is validated by the results of the static method in the identification of normal contact stiffness.
