Simulation Analysis of Cab Mounting System of Flat-head Truck

Abstract

Because the working environment of heavy truck with flat head is harsh, it is often in full load or vibration and impact load for a long time, and the cab suspension system receives these responses, and the driver’s intuitive feeling is the output response of the system. In this paper, the static and dynamic characteristics of air spring are tested, and the stiffness and motion characteristic curves are obtained. Then, according to the test data, the model of cab air mount system is established in ADAMS software, which simulates the response of cab mount under real vibration and evaluates its vibration reduction performance.
