6-DOF Transducers for Multiaxial Elastomer Test Systems

A true 6-Degree-of-Freedom load cell engineered specifically to fill the transducer void in legacy 6-axis elastomer and suspension bushing test frames.

The Missing Metrology Link Advanced multiaxial elastomer test systems were originally designed to conduct durability testing in six degrees of freedom. These legacy frames were architected with a physical mounting block intended for a 6-DOF force transducer at the specimen adapter. However, the OEM never manufactured the specialized load cell required to fill this space.

Without a direct-measurement multiaxial sensor, facilities executing complex Cartesian coordinate control are forced to rely on indirect actuator force feedback. This methodology introduces severe cross-coupling errors and mechanical binding friction into the data stream, completely masking the true localized compliance of the bushing.

SE-6DOF-BSH Architecture: The Drop-In Solution

The SE-6DOF-BSH is a massive, monolithic multi-axis load cell designed to perfectly replace the OEM blanking block. It instantly transforms the test frame into a high-fidelity force measurement system.

• High-Sensitivity Torsional Axis (Mx): Suspension bushings undergo severe rotational displacements, with typical test profiles commanding θx rotations up to 15°. To capture this extremely fine rotational compliance, the SE-6DOF-BSH features a highly sensitized Mx measurement bridge with a dedicated 2 kNm full scale.

• Massive Multi-Axis Rigidity: While isolating the highly sensitive Mx torsion, the monolithic structure simultaneously supports and uncouples massive dynamic loads, including 50 kN Fz / Fy sheer forces and massive 12 kNm My / Mz overturning moments.

• Inertial Error Reduction: Engineered to complement the machine's native acceleration compensation algorithms , the transducer's ultra-stiff structural topology and lightweight mass reduce inertial errors in the force measurement during dynamic, high-frequency durability testing.
