Mechanical vibration law monitoring device

Abstract

The invention discloses a mechanical vibration law monitoring device. The device comprises a bottom plate, two side plates are fixedly connected to the upper end of the bottom plate in a front-back symmetrical mode. A vibrating mechanism is arranged between the side plates; the vibrating mechanism comprises a vibrating plate which is arranged between the side plates in a sliding manner; a throughgroove is formed in the vibrating plate in a front-back penetrating manner; two rollers are arranged in the through groove in a rolling manner; two supporting plates are connected between the two supporting plates; optical shafts are connected with the internal portions of the rollers in the sliding mode. By directly monitoring the vibration amplitude and the vibration period of the vibration plate, the vibration rule of the vibration plate during actual vibration is obtained, the excitation and damping of the vibration plate before vibration can be changed, and then the relation between the vibration rule of the vibration plate and the excitation and damping is obtained.

Description

technical field [0001] The invention relates to the field of mechanical vibration, in particular to a device for monitoring the law of mechanical vibration. Background technique [0002] Mechanical vibration refers to the regular reciprocating motion of an object or particle near its equilibrium position. The strength of the vibration is measured by the vibration quantity, which can be the displacement, velocity or acceleration of the vibrating body. [0003] Existing mechanical vibration test methods are calculated through theoretical analysis, and there is a difference between theoretical analysis and mechanical vibration in actual conditions. Existing mechanical vibration test devices are all tested under certain vibration conditions and cannot be tested. Conditions and factors affecting mechanical vibration, a mechanical vibration law monitoring device described in the present invention can solve the above problems. Contents of the invention [0004] In order to solve...
