Build the experimental model vibration for powertrain of light truck

Abstract

The powertrain of a typical light truck includes an engine, a clutch, a gearbox,
a transmission shaft, a drive transmission, a differential, and two halfshafts
connected to the two wheels, which altogether result in a complex operation.
The twisting oscillations in the powertrain system occur in the frequency's
range from a few Hz to a few kHz as the load varies due to engine torque,
clutch clearance, gears, helical or hypoid gears. Furthermore, bending
vibrations occur at low frequencies depend on the resistance to bending of the
powertrain system, which causes the system to move both traversely and
longitudinally along the direction of the vehicle’s motion. These movements
are the cause of vibration in the truck. This paper presents a method to build
the Experimental Model Vibration for Powertrain of Light trucks. This work
is built with the use of the following equipments: test bed of closed-loop
power, open-loop power and real-time test on the light truck. The results of
the study will help the users select the appropriate testing methods.
