In this paper, the inverse force analysis of planar three spring system is studied using numerical continuation. All static equilibrium positions of the system is obtained.

Is given the equilibrium solution of the model, is analyzed the model by the method of static state analysis and dynamic analysis, are put forward the policy Suggestions finally.

The static equilibrium position form-finding is the premise of the dynamics analysis of the transmission line, and the precision of the form-finding will materially affect the resultant analysis.
