Truck Suspension Models

Modal studies on a truck frame and suspension

This paper presents a comparative study of conventional Experimental Modal Analysis (EMA) and output-only Operational Modal Analysis (OMA) techniques for estimating the modal parameters of a moderately damped truck chassis. The OMA, without its need to measure input forces, would serve as a convenient methodology to test vehicle structures when response data alone is available. Data has been ac...

Design of a Low Power Active Truck Cab Suspension

Effects of the Truck Suspension System on Animal Welfare, Carcass and Meat Quality Traits in Pigs

The objective of this study was to assess the effects of two types of commercial suspension (leaf-spring (LS) vs. air suspension (AS)) installed on two similar double-decked trucks on blood cortisol and lactate concentration, lairage behavior, carcass skin lesions and pork quality traits of 120 crossbred pigs. The suspension type neither influenced pig behaviour in lairage nor blood cortisol an...

Specifying Truck Movement in Traffic Models Using Cell-DEVS

A specification language was defined to outline sections of cities as cell spaces. The goal is to allow the definition of complex traffic models in a simple fashion for the modeler. Once the urban section is outlined, the traffic flow is automatically set up. In this case, the language was expanded to include the behavior of trucks. The models are formally specified, avoiding a high number of e...

Identification of LPV steering models of a truck

In the paper Linear Parameter-Varying (LPV) models of a road-vehicle are presented, that describe the yaw dynamics, the steering system and the brake dynamics of the front wheels. The scheduling parameter is the vehicle velocity. The identification procedure is also detailed. The aim of the identification is to provide models for LPV yaw-rate controller design. The differential brake control on...
