Compostie damp rubber wirerope shock-resistance isolator

Abstract

The invention is a kind of compound damp rubber steel cable shock resistance and vibration isolating device, belongs to the mechanism field. The skeleton structure of the invention is made up of the upper clamping board, the subjacent clamping board and the spiral high intensity steel cable between the two boards, the two boards are riveted together with clinch and hollow clinch, or connected with head embedded clinch, there sets a tap or straight hole connected to the device and base on the two boards, the above mentioned metal pieces are all covered in the special structure form rubber. The invention solves bid damp, three-dimension deformation and low system free frequency needed by the device, the steel rope won't be rusted, it can use high intensity steel cable to upgrade the intensity, carrying ability, deformation quantity and the binding intensity of rubber.

Description

technical field [0001] The invention relates to an anti-shock vibration isolator, in particular to a composite damping rubber steel wire rope anti-shock vibration isolator, which belongs to the field of machinery. Background technique [0002] With the continuous increase of the high-tech content of modern weapons, the importance and difficulty of impact protection are becoming more and more prominent, requiring vibration isolators to have both excellent shock isolation and vibration isolation dual functions. At present, rubber vibration isolators and stainless steel wire rope vibration isolators are usually used to achieve protection against vibration and impact. According to the study of shock theory, the damping ratio of a shock isolator with excellent performance should be in the range of 0.17 to 0.4, and its resonance amplification factor should be less than 3. At this time, the acceleration response and displacement response of the shock isolation system are the smalle...

AI Technical Summary

Problems solved by technology

However, in practical applications, the upper and lower clamping elements of the vibration isolator are rigidly connected to the base and the isolated equipment respectively, and there is no elastic deformation during operation. Pasting damping materials on rigid elements with almost no deformation will not produce practical effects , so it cannot be promoted

During the search, it was also found that the "Bundeswehr Ship Construction Specifications Translation Collection" compiled by the Science and Technology Development Department of the China Naval Research Institute in June 1998 introduced a variety of vibration isolators on pages 23-24 of the book, but these isolators The resonator still cannot solve the problem of damping required to make the resonance magnification less than 3, so it still does not achieve a more ideal effect
