Squeak & Rattle Shaker for sequential excitation in x-, y- & z-axis

Multi-axis sequential Squeak & Rattle test systems that excite subsystems and components in their vertical, fore-aft (or longitudinal), and lateral directions one axis at a time have been proven to be effective means of diagnosing root causes, paths, etc. Oftentimes the physics of why Squeak & Rattle noises occur are so complicated and not intuitive that it is helpful to excite one direction at a time to diagnose root causes. Exciting with road-measured vibration levels separately in each direction helps in this process to detect and correct.

By combining one our two MB Energizers with a Horizontal Moving Table or 3D-Universal Test Fixture different Squeak & Rattle test systems for sequential excitation in x-, y- and z-axis can be realized. The construction based on MB´s patented flexure mechanism enables smooth and noiseless guidance of the Horizontal Moving Table or 3D-Universal Test Fixture.

MB delivered more than 150 turnkey Squeak & Rattle test systems that meet the strict operating background noise requirements of typical Squeak &Rattle test specifications such as GMW14011, GMW7293TP, BMW PR311.2 and others. The optional Chamber Readiness Kit enables environmental Squeak & Rattle testing inside environmental chambers from -40°C to +60°C including humidity.

 

Horizontal Moving Table for small components like radios, steering columns, set belt retractors etc.
