| Abstract: | A new method for identifying the dynamic parameters of joint surfaces of the mechanical structure is introduced by means of structural modeling which has been performed via FEM cooperated with experimental analysis.It can be applied particularly to the heavy machine which,is rather hard to disassemble or assemble,with this method,the joint parameters of column and swing arm of a radial drilling machine have been identified. |
