Embodiment Construction

[0024] 1) As shown in the figure, first process the shape of the two support rods of the flexible heat dissipation interface, that is, the support rod A 1 and the support rod B 2; the flexible heat dissipation interface between the remote sensor and the satellite itself requires extremely high stability; The flexible unloading groove of the thermal interface should be reflected in the directions of five degrees of freedom respectively. According to the basic principle of the heat dissipation mechanism of the hinge, the present invention respectively weakens the stiffness of the two support rods on the single structural member, that is, performs limited release on five degrees of freedom, and realizes the flexible heat dissipation function.

[0025] 2) Carry out heat treatment on the structural shape of the two support rods of the flexible heat dissipation interface. The flexible heat dissipating interface is made of titanium alloy material, and the shape processing needs to be...

Abstract

The invention discloses a satellite-remote sensor flexible heat sinking joint, which belongs to the field of spatial remote sensor optical instruments using a satellite as a carrier. The satellite-remote sensor flexible heat sinking joint comprises a first supporting rod, a second supporting rod and a plurality of unloading grooves such as an unloading groove a, an unloading groove b and the like. The unloading groove a and an unloading groove d are positioned on the first supporting rod and are mutually parallel; the unloading groove b and an unloading groove c are positioned on the first supporting rod, are mutually parallel, and are mutually perpendicular to the unloading groove a and the unloading groove d; an unloading groove e and an unloading groove h are positioned on the first supporting rod and are mutually parallel; an unloading groove f and an unloading groove g are positioned on the first supporting rod, are mutually parallel, and are mutually perpendicular to the unloading groove e and the unloading groove h; the first supporting rod and the second supporting rod are arranged triangularly; and the unloading grooves on the second supporting rod are fully symmetrical with the unloading grooves on the first supporting rod. When a large spatial remote sensor is assembled and positioned, the system stability is optimal, and the satellite-remote sensor flexible heat sinking joint has higher vibration resistance. A stress environment in a working process is improved, so that the remote sensor is in a favorable working condition, and the imaging quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of optical instruments for space remote sensors with satellites as carriers, and particularly relates to the technical field of flexible interfaces of remote sensors. Background technique [0002] A remote sensor is a conventional optical instrument, while a space remote sensor is a special type of optical instrument carried by a satellite. Its working environment is very special and much harsher than that of ordinary optical instruments. It mainly works in the environment of weightlessness in space, vacuum and direct exposure to solar particle radiation. When the satellite is in orbit, the whole star is in an environment of alternating temperature, and the star itself will produce unpredictable thermal deformation under the action of alternating temperature, and the thermal stress generated by this thermal deformation will directly send to the space optical remote sensor The transfer will cause the optical surface ...
