Squeak And Rattle Test Solutions
Annoying noises like squeaks and rattles have become a significant quality issue for customers of passenger vehicles, light & heavy commercial vehicles, increasingly off-road vehicles, and even airplane applications. These unwanted sounds are a problem for numerous reasons including customer dissatisfaction, sizeable warranty expense, and the overlying difficulty to diagnose and fix. MB Dynamics offers an innovative line of Buzz, Squeak & Rattle (BSR) or Squeak and Rattle (S&R) Test Solutions, focused on helping to eliminate annoying noises through prevention, design verification testing, and production verification testing, before the product reaches the customer.

Squeak & Rattle Sub-System And Component Testing
At MB Dynamics, we’re proud to provide clients in a wide range of industries with quiet, custom turnkey component testing systems for combined squeak & rattle testing as well as durability testing of different components and subsystems (in 1 to 6 DOF). Test items can be excited in one or more axes to understand and characterize the physics and root causes of BSRs. Real-world, on-road vibration conditions are multi-axis simultaneous – vertical, fore-aft or longitudinal, lateral, roll, pitch, and yaw – 6 degrees of freedom or 6 DOF. Affordability drives decisions to find BSRs by exciting in one or two – fewer than 6 DOF. That has been a driving force for MB – be effective at finding BSRs with a lesser number of shakers (DOFs) and thus reduce the test equipment cost of finding BSRs. Vertical-only can be effective; sequential vertical then fore-aft then lateral is one step closer to real-world; creating vibration in four or five axes of response simultaneously is even closer; and full 6 DOF systems that are quiet come closest to duplicating in the lab the on-road conditions. MB offers all these possibilities to meet trade-offs of budget, test time, road replication, and BSR detection effectiveness.

Vibration Analysis Software For Squeak & Rattle Testing
MB BSR Suite
MB BSR SUITE is the complete solution for all measurement tasks in the field of NVH, Squeak & Rattle and Sound Quality testing. Comprehensive analysis and assessment capabilities also enable the use of the BSR Suite for analysis and evaluation of functional and operating noise, vibrational effects on humans as well as the acoustic and haptic feedback of controls and actuators. Predefined test configurations for typical tasks such as multi-channel road load data acquisition, drive-file generation and objective Squeak & Rattle and Sound Quality testing allow for fast and simple operation. Signal statistics and user defined thresholds or reference-curves can be used for objective evaluation of different acoustic or haptic quality criteria. In addition the development and integration of application- or customer-specific analyses and evaluation methods is also possible at any time. Contact MB to find a solution for your measurement task!

Material Compatibility Test System (MCTS)
Automotive squeaks occur when materials in contact rub against one another causing annoying noises from friction-induced stick-slips. Automotive itches are a special category of squeaks that can develop when rubber or plastic rubs against glass or paint. The MB Dynamics Material Compatibility Squeak & Itch Test System (MCTS) is designed and manufactured to subject contacting pairs of materials and actual vehicle parts to precisely controlled interference & motion under in-vehicle environmental conditions in order to acquire, monitor, analyze and report friction and acoustic characteristics with the objective to:
