Damping vibration isolation system and composite damping vibration isolator

Abstract

The invention provides a composite damping vibration isolator comprising a vertical damping vibration isolation mechanism and a transverse damping vibration mechanism. The transverse damping vibration isolation mechanism comprises a clamping ring and a bearing disc. A relative slip in a transverse direction can be produced between the bearing disc and the clamping ring. The vertical damping vibration isolation mechanism comprises a sleeve and a friction block. The friction block is slipped over the sleeve. The friction block is nested in the bearing disc. A relative slip in a vertical direction can be produced between the friction block and the sleeve. Thus, there is provided a damping vibration isolation system comprising a composite damping vibration isolator and a composite damper. When installing and in use, an included angle of 90 degrees exists between an axial direction of the composite damping vibration isolator and that of the composite damper. According to the invention, on the basis of a previous composite damping vibration isolator, the structure is improved and the composite damper is added for auxiliary supporting and eliminating coupled vibration, providing more significant vibration attenuation and impact resistance effects.

Description

technical field [0001] The invention relates to a vibration isolator without resonance peak vibration and impact, in particular to a damping vibration isolation system and a composite damping vibration isolator, especially a system composed of a composite damping vibration isolator and a composite damper. Background technique [0002] In order to meet the needs of combat under informationized conditions, modern ships have become the integration of various electronic information equipment, forming an informationized network from combat command, observation and communication, weapon launch control, etc., including various electronic equipment cabinet. Ship equipment must withstand the assessment of various environmental conditions to ensure its safety and reliability, the most severe of which is vibration and shock. It is difficult for electronic equipment to pass the vibration and shock assessment items stipulated in the national military standard GJB150 without the help of ...
