Abstract

The invention relates to a low-frequency large-displacement horizontal movement vibration bench. The vibration bench comprises a power and control device, a braking device, a transmission mechanism, a driven device and a support device. The power and control device comprises a motor, a frequency conversion box and a speed reducing box. The braking device comprises an electromagnetic clutch and a brake. The transmission mechanism comprises a synchronous belt, a transmission main shaft, an eccentric adjusting device and a bearing support hole. The upper end of the transmission main shaft is connected with the eccentric adjusting device. The eccentric adjusting device is used for adjusting the eccentric distance of the transmission mechanism. The driven device comprises a bench face and a bench face guide rail. The support device comprises a substrate, a substrate guide rail and a horizontal support adjusting piece. According to the invention, by selecting the eccentric adjusting device with the biggest adjusting distance of 100mm, a quite big vibration amplitude value is achieved; the vibration amplitude range is from 0 to + / -100mm; the biggest amplitude is far high than that of other vibration bench in the market; and through control on the rotation speed by the speed reducing box and the frequency conversion device, low-frequency vibration of the vibration bench is achieved.

Description

technical field [0001] The invention relates to a low-frequency large-displacement horizontal motion vibration table, in particular to a low-frequency large-displacement horizontal motion vibration table used in vibration tests and mechanical analysis tests Background technique [0002] The vibration table is also called a vibration generator or a vibration exciter. It is a device that uses electric, electro-hydraulic, piezoelectric or other principles to obtain mechanical vibration. It can generally be divided into mechanical, hydraulic, and electric. The electric vibration table is currently the most widely used vibration equipment. Type vibrating table and electromagnetic vibrating table can provide high-frequency vibration, but the vibration amplitude they provide is small, and the structure is complicated, the design is difficult, the cost is high, and it does not meet the experimental requirements. The mechanical vibration table can provide larger amplitude and lower ...
