Three-way vibrating table

Abstract

The invention discloses a three-way vibration table, and belongs to the technical field of mechanical engineering. The three-way vibrating table is composed of a vibrating motor, an upper plate, a guide rail pair, a middle plate, a lower plate, a guide rail pair, a support, a bottom plate, a spring, a base, a sizing block, a linear bearing, a linear guide rail, an electrical cabinet and the like. According to the three-way vibrating table, the included angle of a fixed eccentric block and an adjustable eccentric block of an output shaft of the vibrating motor and the phase of adjustable eccentric blocks at two ends are adjusted, and so that the purposes of changing exciting force, vibrating strength and the degree of unbalance of vibration are achieved. In addition, the working frequency of the vibrating motor, frequency changing modes, the operating time of a certain frequency and the like are controlled by the electrical cabinet, and therefore the upper plate, the middle plate and the lower plate of the vibration table are enabled to generate various vibrations of different directions and different strengths.

Description

technical field [0001] The invention relates to a three-way vibrating table, which belongs to the technical field of mechanical engineering. Background technique [0002] In production, engineering practice and scientific experiments, mechanical vibration is a ubiquitous phenomenon. With the development of modern industrial technology, especially the rapid development of transportation and national defense industries, many equipments are often faced with the severe test of working in harsh environments. The load equipment produces strong vibration, so the reliability and dynamic characteristics of the equipment are increasingly required. Therefore, the research analysis and test simulation of the vibration environment are of great significance to scientific research and engineering applications. [0003] Vibration tests, research and mastery of vibration laws can effectively realize the optimal design of mechanical structures and the prediction of equipment vibration, so a...

Problems solved by technology

[0011] Many test pieces, especially those in the aerospace and shipbuilding industries, are not in a single-degree-of-freedom vibration environment, but in a multi-degree-of-freedom environment, so it is impossible to use the commonly used unidirectional excitation vibration table to realize its real vibration environment
