Buzz, squeak and rattle (BSR) testing utilises real life data files to simulate different road profiles which helps to isolate the causes of unwanted audible noises in an automobile. The road simulations therefore are able to provide repeatability during testing. After the testing and evaluation of unwanted sounds, recommendations on how to eliminate them are provided.
TÜV SÜD revolutionized road simulation testing with the introduction of the silent and efficient servo electric road simulator. Watch the video to learn more about our complete solution to detect, diagnose and eliminate annoying sounds as part of design or production verification and to help solidify your best in class quality reputation.
Buzz, squeak and rattle analysis provides automobile brands with several key benefits:
TÜV SÜD has been conducting BSR tests with leading automobile manufacturers on-site around the world for over 20 years, working to identify and resolve the root causes of BSR. Our highly qualified technicians have decades of experience in the automobile industry and can put your vehicles through extensive and rigorous testing to get straight to the source of the problem.
In addition to those on-site services, TÜV SÜD designs and builds customised solutions for BSR, NVH, performance and durability testing as well as other automotive assessments to meet your specific application and requirements. We are equipped to carry out buzz, squeak and rattle analysis on all kinds of vehicles, utilising cutting-edge, BSR testing, techniques such as servoelectric actuator technology, which is far ahead of hydraulic or electromagnetic actuation in terms of key performance metrics, including force, velocity, acceleration, root mean square (RMS) error, NVH and energy consumption. SEA technology also delivers higher performance and accuracy, resulting in an increased frequency of repeatable tests.
With TÜV SÜD, you have a one-stop solution partner who assists you from the development phase to performance and durability in implementing product and process improvements to isolate and eliminate BSR.
As an independent third-party service provider, TÜV SÜD offers complete solutions, from on-site testing services to the development of customised testing equipment.
TÜV SÜD’s on-site testing services team has partnered with top tier OEMs for more than twenty years, delivering testing services, root cause analysis and knowledge services, including:
TÜV SÜD designs and builds custom-designed BSR test rigs to simulate road conditions to isolate root causes of unwanted sounds audible to drivers and passengers. Specific types of test rigs include:
Our test rigs include single and multiple specimen damper performance and durability test systems, elastomer characterisation test stands, single and multi-axis vibration systems, modular above ground or transportable servoelectric actuator (SEA) four poster testing systems, with the latter introducing the possibility of silent and efficient servoelectric road simulation.
Our qualified test technicians can be placed at your facility to utilise your customised solutions to conduct testing offering and impartial service and providing full reports including root cause analysis where required.
Receive a direct comparison of servohydraulic and servoelectric four poster test systems.
Ensure high performance and reliability of innovative battery Systems.
Achieve compliance with WLTP and RDE requirements.
