5m-Diameter OTR Tire Drum Test Machine

Product Name: Tire Force and Moment Test Machine
Product Info: Design Standard: SAE J1987--Force and Moment Test Method SAE J1106--Laboratory Testing Machines for Measuring the Steady State Force and Moment Properties of Passenger Car Tires Measuring Items: Six tire forces and moments in steady-state under pre-set slip angle
More Info:
Test machine consists of main machine, motor driving system, hydraulic load system and control system.
The drum surface is coated with high anti-wearing material such as SiO, which is driven by DC motor and controlled by Siemens SIMOREG DC Master.
Loading and Positioning system is driven by hydraulic servo system in closed-loop control.
Positioning system consists of two transmission systems. First transmission systems generates the tire camber angle. The second transmission system generates the tire slip angle.
Measuring system is of high technology, which can be controlled by PLC and IPC, and which completes with transuders and electronic chipset etc.
This machine completes with measuring and recording functions, which can measure the normal force (Fz), lateral force (Fy), aligning moment (Mz), slip angle (α ), loaded radius (R), Longitudinal force (Fx), overturning force (Mx), and rolling moment (My).
