Abstract
As suspension of vehicles is generally designed for maximum load, its driving performance for light loaded cases is poor. Additionally, a hard suspension leads to dynamic peak loads on the vehicle structure and freight resulting in an increased noise level. Hence especially in trucks adjustable pneumatically driven suspension systems are commonly used. However, these systems are high maintenance and expensive compared to classic metallic leaf springs. Within the research of the collaborative research centre (SFB) 639 an innovative adaptive lightweight suspension system consisting of glass fibre-reinforced polypropylene (GF/PP) leaf spring elements is designed. Via a component integrated hydraulic system different levels of stiffness can be applied to the spring element depending on the loaded mass and road properties in order to reduce accelerations of the load platform and vibration peaks of the freight. Especially when transporting loose freight a reduction of mass acceleration is a basic possibility to reduce noise emission. Through a detailed multi-body simulation of a demonstrator vehicle, reduced amplitudes of platform acceleration and dynamic wheel loads were determined when using the novel suspension system. Considering multiple operation conditions, the ascertained results indicate a significant reduction of noise emission.
