Bidirectional data conversion of model drawing and data file is supplied, and it can communicate with many finite element system or user programmed system.

Nonlinear physical parameters of the docking mechanism-inertial, damping and stiffness matrices, are identified by direct parameter estimate(DPE)method with input-output data of the system.

A mathematical model of five degrees of freedom is established. And an automatic docking system with CCD auto-collimator, CCD signal receiver, embedded computer, and actuating mechanism is designed.
