This machine is the main machine of tire noise lab. Tire noise lab consists of 3 parts, ie. lab room with acoustic insulation material, sound absorber, noise measuring system, and noise measuring machine.
This test machine is driven by 4-quadrant DC drive cabinet to drive DC motor, which drives drum rotating. The vertical station will be leaned onto drum under the load of hydraulic cylinder to measure tire noise.
Hydraulic cylinder is controlled by servo valve, hydraulic system is a closed-loop loading system.
Characteristics:
(1) Machine structure is a high-stable machine frame, which completes with 3m diameter drum, verticall installation way, and high anti-vibration system.
(2) Drum has passed finite element calculation and dynamic balance test,  which can ensure that the machine runs stably when it is running at high speed and under big load.
(3) The machine employs the speed and load in closed-loop control, which the automation and controlling is very precisely.
(4) Machine completes with versatile controlling capability and simple operation interfaces, which is easy for user operating.
All components and electric parts are chosen from internaional famous-brand companies, which keep the machine running stably and have longer service life.
