A study on the characteristics of rolling barriers

A small Korean manufacturing company invented a new concept longitudinal barrier, the Rolling Barrier RB, which has continuous pipes covered with urethane rings. This study aims to evaluate the effectivenes of the RB, and to understand the RB's characteristics of crash cushioning, how to correct the vehicle's running direction, and the required strength of barriers.

A Study on the Characteristics of Rolling Barriers. By Kyung-Whan Kim* and Bu-Yong Shin** Abstract. In 2001, there were 3,638 traffic accidents on the freeways of Korea, with 54.2 percent composed of vehicles that crashed into longitudinalbarriers. Such accidents can be drastically reduced if more safe barriers are installed for traffic safety.

An Experiment Study on the Dynamic Characteristics

It is therefore necessary to study the dynamic behavior of linear rolling guide. And external load is a factor that affects the dynamic characteristics of linear rolling guide. In this paper experimental approach was used with the aim of studying effects of external load on dynamic behavior of linear rolling guide.

A study of the influence of the rolling of moving part

Firstly, the reason of rolling and the influence on dynamic characteristics are studied. In the design of actuator we should pay attention to three important points, which are the gravitational point, the equivalent driving force point and the equivalent sustained point.

A Study on the Characteristics of Oxide Scale while Hot

In this present study, the deformation behavior of oxide scale was investigated on two types of scale, the primary at 330-512μm in thickness and the secondary at 41-80μm in thickness. After rolling, it was observed that the thickness of secondary scale

Study on Rolling Characteristics of the Projectile

formed verify numerical simulation, so that the latter method can be applied to study the rolling characteristics widely combining theoretical models. n the theoretical part, the rolling dynamics I equations are established considering the, taper spanratio and oblique angle of the empennages, and are further solved combing ballistic equations.

Study on Rolling Characteristics of the Projectile

Due to requests on high rotary velocity of novel smart empennage-stable projectiles, the rolling characteristics under wide-angle oblique angles are studied. Since the wind tunnel tests performed verify numerical simulation, so that the latter method can be applied to study the rolling characteristics widely combining theoretical models. In the theoretical part, the rolling dynamics equations...
