Test bench supports brake hydraulic pressure systems
MB Dynamics has announced the Model BHP/EPB, a test bench for automotive brake hydraulic pressure (BHP) & electric parking brake (EPB) systems R&D. The Model BHP/EPB test bench accurately measures and controls the hydraulic pressure and EPB power levels applied to brake calipers and drums during automotive squeak and rattle, or BSR testing, under a variety of pressure conditions. It does so, in accordance with GMW16316, ‘Objective Brake Component Squeak & Rattle Test’ procedures.
The test bench also supports automotive brake caliper development and qualification testing, during which articles are subjected to various automated brake fluid pressures & EPB controls. It further allows for mileage accumulation, performance cycling, and other forms of brake durability testing, with full manual control of brake caliper parameters, as required for troubleshooting, warranty, and other R&D requirements.
The MB Dynamics Model BHP/EPB automotive test bench software commands the system to either perform data acquisition and control of applied brake pressures; or, to apply and/or release the EPB. Varied hydraulic brake and EPB caliper pressure levels may be applied according to timing diagrams, with automated cycling of different pressures, ramp rates, ON/DWELL times, OFF times, and total test times. Displayed test bench data may be saved at any time and exported to either an Excel or a Windows-based PC clipboard.
These and other features allow the Model BHP/EPB to support automotive industry assessments of brake caliper and rotor assembly noise, useful service life, and other critical brake performance metrics.
