MB Dynamics introduces non-hydraulic steering module test simulator
MB Dynamics, Inc. announced a non-hydraulic Steering Module Test Simulator (SMTS). The SMTS is intended to offer accurate, reliable, and repeatable in-laboratory simulations of driver, road, and vehicle inputs and their associated effects on steering system performance and annoying noises. The test benches can be used to effectively detect the root causes of airborne and structure-borne noises, known as rack rattle, clatter, reversal clunk, and zipper and running noises, in columns, gears, I-shafts, column electric power steering (EPS), and rack EPS units. The system can also be used to help meet both objective and subjective noise, vibration, and harshness (NVH) performance metrics; accurately characterize steering system sensitivity and performance; experimentally verify EPS functions; and to achieve other steering system performance goals, over a vehicle’s full warrantied service life. A typical non-hydraulic SMTS turnkey system from MB Dynamics includes an electrically and acoustically quiet rack load simulator capable of simulating tie rod forces to 25 kN, as well as strokes from 20 mm pk-pk to 250 mm pk-pk. Also available are acoustically and electrically quiet driver simulators for inputting and controlling steering wheel position, velocity, and/or torque values to columns and I-shafts from 10 N·m to 150 N·m. A series of PC-based dynamic controllers further incorporate supplied sensors and signal conditioning to acquire angle, displacement, force, acceleration, and torque parameters, as required for multi-axis closed-loop control. Additional options include gear fixtures, column stands, a compact mobile measurement system for road load data acquisition (RLDA); and an NVH test analysis system, for the recording and objective evaluations of noise and vibration parameters. As a non-hydraulic system, the SMTS requires no oil for operation.
