Rollover threshold investigation of a heavy-duty vehicle during cornering based on multi-body dynamics

Heavy-duty Vehicle Rollover Detection and Active Roll Control

The safety of road vehicles depends on the yaw-roll dynamics. A loss of roll stability results in a rollover accident. Mechanisms to warn against rollover threat and a rollover avoidance control methodology are crucial in designing a successful active safety warning/control system for heavy-duty commercial vehicles. A dynamic rollover metric, Time-To-Rollover (TTR), has become popular in rollov...

Investigation on Emergency Brake Property of a Heavy-Duty Vehicle Based on Functional Virtual Prototyping Model

A Functional Virtual Prototyping full vehicle model for a tri-axial heavy-duty truck is built, and the nonlinearity of suspension dampers and tires is also considered. With the trajectory of full vehicle gravity center, longitudinal tire force of front wheel, longitudinal acceleration, lateral acceleration, yaw rate and pitch angle as the evaluation indexes of brake property, the influences of ...

An Investigation on Crash Worthiness of Different Vehicle Brands: A Case Study of Rollover Crashes

This study aimed at indexing crash worthiness capability of 20 most frequently used car brands in Iran. Since rollover crashes are one of the most important crash types due to their high impact on crash severity, they were chosen as the case study of the current research. In this regard, the data of 42,118 rollover crashes of urban and rural roads of Iran which occurred from 2009 to 2012 was us...

Artificial Neural Network Based Multi-Objective Evolutionary Optimization of a Heavy-Duty Diesel Engine

In this study the performance and emissions characteristics of a heavy-duty, direct injection, Compression ignition (CI) engine which is specialized in agriculture, have been investigated experimentally. For this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (BSFC), peak pressure (PP), nitrogen oxides (NOx), carbon dioxide (CO2), Carbon mon...

Heavy Vehicle Rollover Propensity At Roundabouts On Highspeed Roads
