MB Dynamics launches test bench for brake hydraulic pressure and electric parking brake systems R&D

LinkedIn +

Auto testing equipment producer MB Dynamics has introduced the Model BHP/EPB test bench, for use when carrying out R&D on brake hydraulic pressure (BHP) and electric parking brake (EPB) systems.

The test bench works by measuring and controlling the hydraulic pressure and EPB power levels applied to a vehicle’s brake calipers and/or drums when under squeak and rattle, or BSR, testing, in a variety of pressure conditions.

Capable of testing the above systems in accordance with GMW16316 (‘Objective Brake Component Squeak and Rattle Test’) procedures, the automotive test bench also supports brake caliper development and qualification testing, where components are subjected to various automated brake fluid pressures and EPB controls.

The system also enables mileage accumulation, performance cycling and other forms of brake durability testing, with full manual control of brake caliper parameters to aid with troubleshooting, warranty work and other any other requirements of the R&D process.

The software within the test bench can command the system to perform either data acquisition and control of applied brake pressures or to apply and/or release the EPB. Alongside this, 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 can then be saved at any time and exported.
