The invention discloses a flexible auxiliary supporting structure, a pre-tightening force applying device and a pre-tightening force interpretation method. A support connection mode combining compression ring type flexible auxiliary support and rigid main connection can improve the stress condition of a supported part and improve the dynamic environment adaptability of the supported piece; through the structural design of auxiliary supporting parts of a supporting piece and the supported piece, a containing cavity with a rectangular or square section is formed, and axial pre-tightening force can be well converted into transverse supporting force through axial sleeving loading; the transverse supporting force on the supported piece is approximately in direct proportion to the axial pre-tightening force of a compression piece, and the axial pre-tightening force can be adjusted according to requirements by adjusting the thickness of a gasket; through cooperation of the pre-tightening force applying device and th
