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.
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.
