車輛異音測試

為各個關鍵領域帶來真正的商業利益

什麼車輛異音(BSR)測試?

車輛異音測試一般會涉及道路模擬測試,這種測試可以將在車內產生刺耳雜訊的各種振動的根源與路面不平區分開來。因此,道路模擬可以在測試期間提供可重複性。測試和評估異音後,給出如何消除異音的建議。

TÜV SÜD推出高效靜音伺服電動道路模擬方法,革新了道路模擬測試。觀看影片,瞭解關於我們設計或生產驗證中的完整檢測、診斷和消除異音解決方案以及我們如何幫助您鞏固優秀品質聲譽的更多資訊。

Why is a BSR test important?

Buzz, squeak and rattle analysis provides automobile brands with several key benefits:

  • Boost customer confidence in your product – while BSR may not be related to the vehicle’s safety, many customers perceive unwanted noises as dangerous or irritating
  • Enhance your brand’s reputation as a reliable manufacturer
  • Unresolved noise issues can result in costly rework and repairs during the manufacturing process – BSR testing helps you isolate them early

TÜV SÜD is a global leader in BSR testing

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.

TÜV SÜD’s BSR solutions and testing services

As an independent third-party service provider, TÜV SÜD offers complete solutions, from on-site testing services to the development of customised testing equipment.

On-site BSR testing and auditing services

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:

  • BSR resolution at OEM factory, including support in design guides, validation as well as maintenance
  • Four poster BSR testing, quality audits and drive file replication comparison
  • Body air leak/wind noise testing at OEM factory
  • Full-service competitive vehicle benchmarking

Building custom-designed BSR test rigs

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:

  • Fixed, Ambient or Environmental Four Poster (FAFP or FEFP)
  • Fully Transportable Ambient or Environmental Four Poster (TAFP or TEFP)
  • Modular Above Ground Ambient or Environmental Four Poster (MAGAFP or MAGEFP)

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.

On-site staffing solution

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.
