Vibration isolator system dynamic performance testing test platform and testing method

Abstract

The invention provides a dynamic performance test platform of a vibration isolator system. A vibration isolator is placed at the center of a base platform, a mass component is placed at the top of the vibration isolator and is detachably connected with the vibration isolator, a vibration exciter mounting bracket is installed on the base platform and is used for hanging a vibration exciter right above the mass component, a vibration input rod is arranged at the bottom center of the vibration exciter and is detachably connected with the mass component to transfer the vibration of the vibration exciter onto the mass component, a guide bracket is further installed on the base platform, is vertical to the base platform and is detachably and movably connected with the mass component, the mass component can only move along the guide bracket under the limit of the guide bracket, a force sensor I is installed on the vibration input rod, a vibration sensor is installed on the mass component, a force sensor II is installed at the bottom center of the vibration isolator, and the mass of the mass component is smaller than 1000 kg. The invention further provides a dynamic performance test method of the vibration isolator system.

Description

technical field [0001] The invention relates to the technical field of vibration isolation performance detection of vibration isolators, in particular to a test platform for testing the dynamic performance of a vibration isolator system and a method for testing the dynamic performance of a vibration isolator system using the test platform. Background technique [0002] With the improvement of living standards, people's requirements for vibration and noise are becoming more and more stringent, and people are paying more and more attention to the ride comfort and ride comfort of vehicles, and the protection requirements and vibration control level of mechanical equipment, especially precision equipment The requirements are getting higher and higher, and vibration isolators are widely used in mechanical equipment to reduce noise and vibration. Testing the dynamic performance of the vibration isolator when it is in use can accurately understand the noise reduction and vibration ...

Problems solved by technology

[0005] However, the national standard GB / T 15168-2013 vibration and shock isolator static and dynamic performance test method only gives the mechanical model of the excitation scanning method, and does not give the specific test platform structure for the dynamic performance test using the excitation scanning method , there is no standardized and standardized test platform for the vibration exciter scanning method, so a test platform with simple structure and strong practicability is proposed to improve the standardization and standardization of the dynamic performance test of the vibration isolator system by the vibration exciter scanning method, so that the vibration isolation It is quite necessary to make the test process of the dynamic test of the device system more simple, flexible and easy to operate
