Continuous Automatic Measurement of Static Spring Constant and Dynamic Properties before and after Durability Tests on Rubber Vibration Isolators by Combination Test Software

User Benefits

- Tests based on JIS K 6385 can be performed. - Combination test software enables continuous and automatic measurement of static and dynamic properties before and after durability tests. - The high frequency response of the EMT series enables testing at high test frequency.

Introduction

A rubber vibration isolator is a product designed to prevent or mitigate the transmission of vibration and shock. It is widely used in various fields such as transportation equipment, construction, and industrial machinery. JIS K 6385 “Rubber vibration isolators - Test methods” defines several test methods and terms for evaluating the performance of rubber vibration isolators. In order to estimate the fatigue life of rubber vibration isolators, a durability test method is specified in which the rubber vibration isolator is subjected to repeated loads to evaluate the presence of failure, cracks, or changes in properties. It is extremely important to evaluate the durability of rubber vibration isolators because deterioration in their performance can cause noise and instability. Shimadzu’s fatigue and endurance testing machine Servopulser’s Windows Software for 4830 has a function called a combination test, which automatically combines several tests and continuously executes them. This article introduces an example of continuous automatic measurement of static spring properties and dynamic properties of rubber vibration isolators before and after durability tests, by using a combination test.
