6-Component Wheel Force Measuring System

Compact and Lightweight 6-Component Wheel Force Transducer SLW-25KNF

The main unit has been lightened from 5.2 kg to 3.3 kg, thereby mitigating the increase in unsprung weight. And the capacity of the three-component wheel forces has been increased from 20 kN to 25 kN. The Three Moment has been expanded from 3 kN to 4 kN, and the number of measuring vehicles has been diversified. In addition, for the purpose of reducing the accumulation of conducted/radiated heat in the six-component wheel force transducer during braking, the six-component wheel force transducer sensing section has been opened, and the effective cool-down running and the extended operable time of the six-component wheel force transducer has been enabled.

Slip-ring type SLW-NC 6-Component Wheel Force Transducer

This is a load cell which measures an external force passed to the tire from the road surface while the car is running, by breaking the force down into orthogonal three-component force and three moments around the force axes. Highly precise measurement is possible in every driving condition owing to its load detecting part with reasonably arranged strain gauges, slip ring and rotary encoder assembly with improved vibration resistance, and waterproof structure. This transducer is used together with the exclusive 6-component force analyzer MF-660. The 6-component force is indicated in a coordinate system based on the car body.

T-ZACCS6 Slip-ring Type Miniature 6-Component Force Analyzer MF-660

The 6-Component Wheel Force Transducer attached to the axle measures the external forces that the tire receives from the road surface in the form of three orthogonal forces and three moments around them.
After digitally converting the strain detected by the 6-Component Wheel Force Transducer, the instrument performs physical quantity conversion, correction for mutual interference between the force components, rotation correction (X and Z components only) using the angle signal from the rotary encoder attached to the 6-Component Wheel Force Transducer, and offset position correction between the 6-Component Wheel Force Transducer and tire center. After calculation, the measured 6-Component Force and tire speed are output as voltage and CAN signals.

Features
  • Compact and lightweight, with connectors concentrated on the front panel, making it easy to install in any space
  • Various correction calculations are processed in real time to calculate 6-component forces
  • Calculated 6-component force data and tire speed are output by CAN signal as well as voltage output
  • Characteristic data of the 6-Component Wheel Force Transducer can be easily set from the included control software
