Large truss type vibration isolation platform structure facing various effective loads

Abstract

The invention provides a large truss type vibration isolation platform structure facing various effective loads. The large truss type vibration isolation platform structure facing the various effective loads comprises a service module, a secondary vibration isolation mechanism and a propelling module, wherein the secondary vibration isolation is arranged at the top of the service module; a load simulation piece is arranged on the secondary vibration isolation; and the propelling module is arranged at the bottom of the service module. Compared with the prior art, the invention is advantaged in that a satellite realizes high adjusting capacity and strong space extendable assembling capacity due to adoption of the large truss structure with light weight, high bearing capacity and good technological property so that the mounting of a plurality of propelling systems and service platform system single machines and equipment is ensured; vibration isolation requirements of high accuracy loads on specific frequency are realized through adoption of primary and secondary vibration isolation mechanisms so that micro vibration responses of the loads are effectively reduced and the working performances of the effective loads at in-orbit sections are improved; and a clamped separating and unlocking device is arranged at a transmitting section so as to realize a supporting structure effect and an unlocking separation effect.

Description

technical field [0001] The invention belongs to the field of aerospace control and is suitable for a vibration isolation platform structure, in particular to a large truss type vibration isolation platform structure facing multiple payloads. Background technique [0002] With the continuous expansion of my country's national defense industry's demand for aerospace, the function and performance of spacecraft payloads continue to improve, and the development of satellite structure platforms is developing in the direction of large-scale, high-load, micro-deformation, and low-response. The payloads of the new generation of military satellites are diversified, and different payloads are difficult to achieve common use of platforms, which will significantly reduce the efficiency of satellite development, increase the development cycle and cost, and make it difficult to meet current and future military needs for rapid development and rapid launch of satellites. At the same time, th...
