6-DOF Multi-Axis Sensors for Kinematic & Compliance Testing
Direct-integration 6-Degree-of-Freedom load cells engineered for automotive Kinematic & Compliance (K&C) Deflection Measurement Systems. Available in Passenger Car (PC), Light Truck (LT), and Commercial Vehicle (CV) load architectures.
The Vehicle Dynamics Requirement
Accurate multibody dynamics (MBD) modeling requires exact isolation of individual load vectors during combined-load roll, pitch, and bounce events. Sensors deployed on K&C test rigs must possess exceptionally low mechanical crosstalk to ensure that applied kinematic displacements and the resulting tire patch/spindle compliance forces are measured without aliasing.
SE-6DOF Architecture
The SE-6DOF series features a highly stiff, monolithic structural topology optimized for the exact force and moment envelopes of industry-standard K&C test rigs.
Platform Matching: Full-scale force (Fx, Fy, Fz) and moment (Mx, My, Mz) measurement limits are mathematically scaled to precisely match the peak actuator outputs of the target test platform.
Crosstalk Rejection: Native geometric isolation combined with precision calibration matrices guarantees off-axis force rejection, providing uncorrupted compliance data even at severe suspension jounce limits.
Direct Integration: Engineered to bolt directly into standard PC, LT, and CV K&C system mounting plates with zero intermediate adapters.
