This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

The effect of risk factors on crash severity varies across vehicle types. objective this study was to explore the associated with rural single-vehicle (SV) crashes. Four types including passenger car, motorcycle, pickup, and truck were considered. To synthetically accommodate unobserved heterogeneity spatial correlation in data, a novel Bayesian random parameters logit (SRP-logit) model is prop...

ABSTRACT: Deceleration or stopping the vehicle without any diving and lateral acceleration is essential to develop an effective braking system. The hydraulic braking system with intelligent braking called Antilock Braking system (ABS) and Electronic Stability Control (ESC) has been introduced.  However, due to the insufficient human effort, the ABS and ESC to some extent, not function well...

A finite element automobile model for use in crash safety studies was developed through reverse engineering. The model was designed for calculating the response of the automobile structure during full frontal, offset frontal, or side impacts. The reverse engineering process involves the digitization of component surfaces as the vehicle is dismantled, the meshing and reassembly of these componen...

Yıldırım / Simulation Modelling Practice and Theory 17 (2009) 778–793 779 developed to control a seat suspension system of non-linear full vehicle model [10]. Yıldırım and Uzmay have been investigated the variation of vertical vibrations of vehicles using a neural network [11]. An active horizontal spray-boom suspension, reduc...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

This paper presents a complete trajectory tracking controller design for an Unmanned Air Vehicle using Linear Parameter Varying design methods. The longitudinal and lateral controllers are designed using an inner loop – outer loop structure with the inner loop LPV controller designed using μsynthesis. The inner-loop is then approximated with a reference model and the outer loop is designed usin...

This paper presents a novel design of a full six-degree-of-freedom, tri-rotor-actuated single-wheeled vehicle. When stationary on the ground, the model of the vehicle mimics an inverted pendulum system, a typical representative of highly nonlinear systems with non-minimum phase and unstable characteristics. The full nonlinear model of the vehicle is derived using Newton-Euler approach, but the ...
