Automotive vibration testing

A Brief Review of Automotive Vibration. Provided By: Mike Gardner, Sasha. Continuous monitoring during vibration test. Specific requirements may vary by. Our vibration testing labs across the U.

For example, electrodynamic ( ED) shakers can .

We have extensive vibration testing capabilities that cater for various classifications of ground transportation .

TÜV SÜD Product Service can help with all your vibration testing and shock testing requirements at our state of the art mechanical testing facilities. Vibration qualification tests are currently indispensable for vehicle manufacturers and their suppliers. The vibration qualification tests are nowadays indispensable for vehicle manufacturers and their suppliers. The same is even truer, for the rail and aerospace industries. However, the need for dynamic vibration tests is currently growing in all sectors of the industry.

Kyosti Vakevainen, Nokia Research Center. Laboratory Testing of Vehicle and Industrial Heat Exchangers for Durability Under Vibration -Induced Loading. This SAE Recommended Practice is applicable to all liquid-to- gas, liquid-to-liqui gas-to-gas, and gas-to-liquid heat exchangers used in vehicle and industrial . Automotive components and subassemblies are increasingly subjected to vibration testing using sophisticated vibration control techniques.

From instrument panels to seats inside the car and from air-bag sensors to fuel injection pumps in the engine compartment, many automotive components are being . Vibration controllers, noise and vibration analyzers, road load simulation, test rigs. To avoid these issues, many automotive manufacturers and automotive suppliers spend millions testing . Vehicle frames themselves are stronger and heavier around the areas where heavy components are located. Manufacturers are discovering that vibration test systems that are currently in use are not necessarily capable of driving the new test loads to required acceleration levels. Apart from increase in the weight of test . This document outlines the test to determine durability characteristics of the heat exchanger from vibration -induced loading. All the test facilities are equipped with high-performance control and measuring systems which cover all . As automotive OEMs shifted costs to their suppliers, they also shifted the majority of testing requirements as well.

There are many ISO standards geared toward automotive vibration testing , however most qualification acceptance standards are published or provided directly by the automotive OEMs. Many in-service product and component failures are caused by fatigue, but these are avoidable with appropriate validation or investigative laboratory vibration testing.
