Sectional collision elastic strengthening type non-smooth vibration absorber

Abstract

The invention discloses a sectional collision elastic reinforced non-smooth vibration absorber, which comprises a front cover, a rear cover, a shell, a guide rail and a mass block, and is characterized in that the shell is detachably arranged between the front cover and the rear cover through a connecting piece; the guide rail is linear, penetrates through the center of each mass block and is in sliding fit with the mass block, and the two ends of the guide rail are fixed to the front cover and the rear cover respectively. At least three mass blocks are arranged on the guide rail at intervals, the mass blocks are all columnar, at least two sets of spring connecting pieces are evenly and symmetrically arranged on the side faces of column bodies of the mass blocks and the inner wall of the shell, each spring connecting piece is composed of a positioning table and a protruding column, the positioning table is provided with an inwards-concave empty groove, and the protruding column is arranged in the empty groove. One end of each protruding column is inserted into the corresponding empty groove and rotationally connected with the corresponding positioning table, the protruding columns of the spring connecting pieces in the same set are located on the same straight line, and springs are fixedly arranged between the protruding columns in a sleeving mode. According to the vibration absorber, the effective use range of the nonlinear vibration absorber can be widened, and the harmful bifurcation phenomenon is restrained.

Description

technical field [0001] The invention relates to the technical field of vibration absorption and shock absorption, in particular to a segmented bump-strengthened non-smooth vibration absorber. Background technique [0002] When the vibration absorber has nonlinear characteristics, during the application process, the excessive external excitation will cause the bifurcation phenomenon of the entire vibration system, resulting in stable and large vibration for a long time, and then lead to the failure of the vibration absorber. This problem makes the nonlinear Vibration absorbers are only effective in a small range of excitation amplitudes. Therefore, there is an urgent need for a vibration absorber that can widen the effective use range of the nonlinear vibration absorber and suppress the harmful bifurcation phenomenon. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a vib...

Problems solved by technology

[0002] When the vibration absorber has nonlinear characteristics, during the application process, excessive external excitation will cause bifurcation of the entire vibration system, resulting in long-term stable and large-scale vibration, which will lead to the failure of the vibration absorber. This problem makes the nonlinear Vibration absorbers are only effective over a small range of excitation amplitudes
