1. Parametric Modal Study and Optimization of the Floor Pan of a B-Segment Automotive Using a Hybrid Method of Taguchi and a Newly Developed MCDM Model
Abstract The floor pan is an important component that connects the front and rear segments of the automotive underbody structure. Global stiffness and NVH characteristics of BIW are highly dependent to shape, thickness and mass of the body panels and could be evaluated by modal characteristics of these panels. The feeling of solidness and comfort of passenge

3. Otimização de parâmetros concentrados de suspensão para conforto e segurança veicular / Optimization of lumped parameters of suspension for vehicle comfort and safety
The present work evaluates the optimization of lumped parameters of suspension on vehicles and considers the importance of this process to minimize the rms vertical acceleration transmitted to ensure comfort and safety to the driver. Thus, this work aims to develop a model able to represent the whole vehicle and, then, optimize the parameters of stiffness an

4. Estudo do ruído de rodagem estrutural através da análise dos caminhos de transferência de energia - TPA / Structure-borne road noise study using transfer path analysis, TPA
The road noise, vibration and harshness (Road NVH) present from 20 Hz to 1000 Hz approximately, begins from the tires vibration and acoustic propagation and their interactions with the road surfaces. In these noise sources, both structural-borne and air-borne noise contributions are relevant to vehicle refinement. The constant efforts to study the vehicle as

5. Synthesis of a Magneto-Rheological vehicle suspension system built on the variable structure control approach
The synthesis of a magneto-rheological vehicle suspension system built on the variable structure control approach is considered in the present work. The suspension is synthesized in order to improve the ride comfort obtained by a standard passive suspension. Although a nominal half-vehicle model with rigid body is considered in the synthesis of the suspensio

7. Optimal design of passenger car suspension for ride and road holding
The primary function of a vehicle suspension system is to isolate the road excitations experienced by the tyres from being transmitted to the passengers. In this paper, a suitable optimizing technique is applied at design stage to obtain the suspension parameters of a passive suspension and active suspension for a passenger car which satisfies the performanc

10. A DYNAMIC INTERACTION MODEL OF TRACK RAILWAY STRUCTURAL ELEMENTS / UM MODELO DE INTERAÇÃO DINÂMICA ENTRE OS ELEMENTOS ESTRUTURAIS DE UMA VIA FÉRREA
In a railway, the vehicle interacts dynamically with a track superstructure (rails, rail pad and sleepers) and sub-structure (ballast, sub-ballast, sub- grade). Passengers comfort, environmental loading (ground vibration) and frequency of maintenance works of vehicles as well as of the track are deter- mined by the way all the structural elements interact. T

11. Estudo de geração de trincas térmicas em discos de freios de veículos comerciais
The disc brake systems, when compared with the drum brake systems currently used in heavy-duty vehicles, resent significant advantages, such as: better performance in relation to temperature and speed and better braking comfort. On the other hand, the use of those systems submits the brake discs to much higher mechanical and thermal stress than that in brake

12. Dinâmica veicular relativa ao ride de veículos e métricas para sua avaliação / Vehicle dynamics related to ride and metrics for evaluation
Using simplified mathematical models this work presents a detailed description of vehicle characteristics that significantly influence ride evaluation. These simple modes were used in order to describe basic vehicle modes of vibration, such as bounce, pitch and unsprung mass ones. The influence of modes of vibration with frame flexibility was also presented
