Problems solved by technology

[0005] a. The existing vibration test needs to carry out three uniaxial tests successively. Professionals are required to perform high-demand adjustment and positioning between the three tests, which takes a long time and is very cumbersome to operate;
[0006] b. The existing vibration test is to let the product undergo three uniaxial vibrations successively to evaluate the performance of the product, which is inconsistent with the real composite vibration environment, there are large errors, and it cannot truly reflect the anti-vibration performance of the product

Abstract

The invention discloses a three-axis vibration test table and a control method. The three-axis vibration test table comprises a frame body, a bottom carrier board, a top carrier board, a test platformand a cross guide mechanism, wherein the bottom carrier board is driven to take a translational motion up and down; the top carrier board is arranged above the bottom carrier board and can be drivento take a translational motion relative to the bottom carrier board; the test platform is fixedly arranged on the top carrier board; the cross guide mechanism comprises two groups of linear guide parts correspondingly and perpendicularly arranged at an interval, a middle plate positioned between the two groups of linear guide parts and guide parts respectively arranged on two lateral surfaces of the middle plate and correspondingly matched with the linear guide parts; and the cross guide mechanism is arranged between the bottom carrier board and the top carrier board. The three-axis vibrationtest table is high in expansibility; and when the three-axis vibration test table is used as a vibration source, a workpiece can be additionally and randomly arranged on a vibration platform and for example, a high-frequency vibrator is additionally arranged, so that application of the three-axis vibration test table is further expanded.

Description

technical field [0001] The invention belongs to the technical field of product detection, and in particular relates to a three-axis vibration test bench and a control method. Background technique [0002] Servo three-axis vibration is a technical upgrade of the vibration of the general automotive turbocharger pipeline system. It is mainly used in the vibration fatigue test of soft and hard pipelines in the automotive turbine system to verify the performance and service life of the turbine pipeline. [0003] The natural vibration experienced by the product under actual working conditions is the composite vibration of the X, Y, and Z axes. Due to the limitation of test equipment and means, the vibration test device can only simulate the vibration of a single axis. Therefore, the general practice of the existing vibration test is: successively conduct uniaxial vibration tests on a certain product, and then comprehensively evaluate the anti-vibration performance of the product b...
