Synthesis of the Active Cab Suspension Mechanism

Abstract:

In the context of growing ergonomic concerns and pressing competition on the market, designing machines and vehicles offering a better operator comfort has become a major trend in development of heavy machines and vehicles. During the ride over the rough terrain, the cab is subjected to excitations in the form of low-frequency and high-amplitude vibration. This study investigates the vibration reduction strategy whereby the machine structure should incorporate an active suspension of the cab. An actuating mechanism is incorporated, connected to the machine frame and the cab and placed in between. This paper provides a synthesis of dimensions of the actuator links such that the imposed constraints and conditions should be satisfied. A numerical example is provided in the study of a Caterpillar 924 Gz loader.
