Abstract

The invention discloses a servo motor drive type large-displacement vibration device and a servo motor drive type large-displacement vibration method. The servo motor drive type large-displacement vibration device comprises a movable table and a vibration controller. The movable table comprises a base, a servo motor, a first ball screw, a second ball screw, a tabletop, a first static-pressure guide rail, a second static-pressure guide rail, a third static-pressure guide rail, an acceleration sensor and a displacement sensor. The servo motor drive type large-displacement vibration device and the servo motor drive type large-displacement vibration method have the advantages that requirements of vibration experiments on low frequency response and large-displacement movement control characteristics can be met by a servo motor and ball screw combined drive type structure; high anti-overturning moment can be generated by the device in vibration experiment procedures owing to static-pressure guide rail structures, so that the stability and the reliability of the vibration device in working procedures can be guaranteed.

Description

technical field [0001] The invention relates to a vibration simulation device, in particular to a servo motor-driven large-displacement vibration device and method. Background technique [0002] Vibration devices are mainly used in the field of vibration environment simulation, such as earthquake waveform reproduction, civil structure pseudo-static, pseudo-dynamic experiments, and vibration environment simulation of packaging products. Conventional vibration devices (vibration tables) include mechanical, electromagnetic, electro-hydraulic and other structures. There is noise pollution in the vibration process, and the achievable vibration displacement is too small. The vibration displacement of electro-hydraulic vibration devices is relatively large, but it is still difficult to meet Low frequency response, large displacement vibration requirements, and environmental pollution. The present invention is aimed at a servo motor-driven large-displacement vibrating device. The d...
