Researching the contribution of coefficient to flexivity;

Through the calculation on flexivity of drag-chainand length of chain curve,set screw-pull-ing instrumentneeds to be adaptedto suitable period.

This paper expounds the components and working principles of the beam for military purpose, introduces the calculation of the flexivity generated by the construction load, and probes into the application and promotion of the technology of the military beam.
