The rollover accidents in the tractor semi-trailer are often fatal and many factors could cause the tractor semitrailer rollover. In this paper, a rollover prevention control method was proposed based on real-time calculation of rollover index. The vehicle Center of Gravity CG height from the ground is an important parameter in the rollover index and it is estimated through lateral acceleration...

With the features of high centroid, high load capacity and high aspect ratio, heavy vehicles are prone to rollover when running at high speeds in the corners, so the study of heavy vehicle rollover warning method presents important realistic meanings. In this paper, firstly, the composition of early warning systems is analyzed, and then the principles of rollover warning method based on suspens...

Background Footwear with a curved sole profile has become popular due to the proposed benefits to gait, posture and altered muscle activity and tone. In addition, rocker profiled footwear are one of the most commonly prescribed therapeutic shoes [1-4]. The altered movement of the body over the foot due to the curved sole profile is assumed to alter the position of the hips and thereafter the tr...

This paper proposes a methodology that allows the combination of the Stability Factor and handling characteristic to predict the probability of rollover per single vehicle crash. Paper No.202-O Simulation of Occupant Kinematics in Vehicle Rollover Dummy Model versus Human Model Norbert Praxl, Markus Schönpflug, Jiri Adamec Institute for Legal Medicine Munich, Germany Abstract Currently, 25% of ...

This paper describes an unified chassis control (UCC) strategy to prevent vehicle rollover and improve maneuverability. In order to detect a danger of rollover, rollover index (RI) which indicates an impending rollover is determined. The rollover index is calculated using estimated roll angle, roll rate and measured lateral acceleration. Lateral and vertical model-based roll state estimators ar...

This paper details the injuries occurring in real world trip-over only rollover crashes, for seat belted and contained occupants, and assesses whether these injuries can be replicated using a Jordan Rollover System (JRS) crash test rig recently installed at Crashlab in Sydney. This research forms part of the Dynamic Rollover Occupant Protection (DROP) project funded by the Australian Research C...

Types of vehicle rollovers can be classified into two categories: untripped and tripped. Untripped rollovers are relatively rare events resulting from high lateral friction forces between the tires and road. Tripped rollovers are the result of lateral forces caused by the tire or wheel digging into the road or ground or from striking a curb or other obstacles. As reported in the open literature...

Rollover is not the most common type of accident, but the consequences may be serious. Understanding of the injury mechanisms during the complex rollover movement is limited and requires further investigation. ln-depth investigations of 21 Volvo cars involved in rollover crashes were analysed with regards to cause and outcome. Detailed information was examined about the crash scenario, the road...

As product life cycles shortened, many firms introduce new products and phase out old products frequently. To plan for a successful product rollover; i.e., introduce a new product and eliminate an old product successfully, a firm needs to determine the prices of both products as well as the time to launch the new product and the time to phase out the old product. In this paper, we develop an an...

CONTEXT There is an increased awareness of the problem of rollover crashes, but few data on children involved in rollover crashes in the United States. OBJECTIVE To determine: (1) the rates of rollover crashes involving children and the incidence of fatal injury; (2) the characteristics of crashes involving children; (3) the risk factors for children being in a rollover compared with a non-ro...
