SWIFT 10 ATV Sensors

Construction

Hardware Overview

Construction

The SWIFT sensor has one-piece construction for outstanding fatigue life, low

hysteresis, and high stiffness. Its compact package has a minimal effect on inertia

calculations, and a minimal dynamic effect on the test vehicle.

The transducer can be used for developing conventional durability tests on the

MTS Model 329 Road Simulator. Normally, the transducer is replaced with an

equivalent wheel adapter after the simulation drive signals are developed and

prior to the start of the test.

The SWIFT sensor includes several mechanical and electrical components.

Transducer The transducer attaches directly to a modified wheel rim. On the test track

vehicle, the transducer spins with the wheel. On a road simulator, the transducer

attaches directly to an adapter plate on the 329 spindle housing. The slip ring can

be used to accommodate the range of motion of the rear swing arm.The

transducer is available in two materials.

The transducer’s unibody design means there are no multiple parts welded or

screwed together.

The transducer has four beams with strain gages that measure six orthogonal

outputs:

Fx—longitudinal force

Fy—lateral force

Fz—vertical force

Mx—overturning moment

My—acceleration and brake torque

Mz—steering moment

It has onboard conditioning and amplifiers to improve the signal-to-noise ratio.
