The shirt rim thickness that described support skirt section is divided is 2mm ~ 3.5mm, and tilt angles is 8 ° ~ 15 °.
The thickness of described flange section is 6mm ~ 10mm.
The number of described mounting hole, the number of namely described gap is 16,24,32,40 or 48.
Described gap is isosceles trapezoid supporting the cross section divided in skirt section, and trapezoidal height is 10mm ~ 20mm, and two waist angles are 35 ° ~ 45 °.
Described flange section forms auricle structure after open and clear mouth, and described gap divides the base width in isosceles trapezoid gap cross section identical with described supporting skirt section at the width of described flange section.
Described flange section auricle structure is multiple isosceles trapezoid in the situation of overlooking, and trapezoidal base is 60mm, and top margin is 36mm.
The present invention compared with prior art beneficial effect is:
(1) the present invention adopts the flange form of annular open and clear mouth to support the version of skirt; the advantage of flange form mounting structure and support skirt-type mounting structure is combined together; compared with prior art, there is good resilient mounting ability, when bearing load; especially when bearing lateral acceleration;, uniform load can be distributed on whole ring surface, avoid single-point stressed too concentrated; the load that tank housing receives can be cushioned simultaneously, effectively can protect tank.
(2) mounting structure of the present invention is applicable to the installation of truss type platform satellite propulsion system Large Copacity propellant tank completely, compared with prior art, improve the ability that tank bears every load, reduce the installation difficulty of tank on star, be conducive to the structural reliability and the safety that improve whole star, be conducive to the loss of weight of whole star architecture quality simultaneously.
(3) mounting structure of the present invention has been applied on certain truss type platform satellite tank, after tank filling simulated solution, carry out whole star dynamic environmental test and tank qualification level dynamic environmental test, all withstood the test of mechanical environment, mounting structure is well stressed, and performance is completely normal.
