Identification of Inertial Parameters of Heavy Truck Powertrains

Based on the quality of line frequency response function and the principle of rigid body micro-vibration, a technique was proposed to verify the experimental accuracy for the heavy truck powertrain by using rigid body inertia tensor transformation and additive theory. The measurement of inertial parameters of a heavy truck powertrain was carried out by hammer method. The total least square processing theory was proposed to process the experimental data. The experimental results showed satisfactory accuracy and reliability.
