Effect of tractor-semitrailer velocity on cornering braking stability LI Chena, SONG Shangbinb, TANG Getengc, SHI Huiqid Key Laboratory of Operation Safety Technology on Transport Vehicles Ministry of Transport Research Institute of Highway Ministry of Transport, Beijing, China ac.li@rioh.cn, bsongshangbin1982@sina.com, cgt.tang@rioh.cn, dhq.shi@rioh.cn Key words: Automotive Engineering; Tractor-semitrailer; Velocity; Cornering Braking; Stability Abstract: A dynamic model of tractor-semitrailer cornering braking was established in this paper.
Bad directional stability of tractor-semitrailer will result in the phenomenon of folding, snaking and shimmy, even road traffic accident[2].
China has not yet developed technical standards for heavy commercial vehicles cornering braking performance test method, so the test referred ISO 14794:2003 regulations drew up by the International Organization for Standardization.

One approach for achieving collapse resistance is to provide maximum safety against failure for all critical elements.
Accidental circumstances that include ship impact, overload traffic and simply corrosion, or other accidental actions should be minimized or designed for.

Steering Analysis of Multi-axle Vehicle Based on ADAMS/VIEW Yongqiang Zhu 1, a, Pingxia Zhang 1,b 1 School of Automobile and Traffic, Qingdao Technological University, Qingdao, Shandong, 266520, China ayongqiangzhu@163.com, bzpx614@163.com Keywords: ADAMS;double-phase;multi-axle;full wheel steering Abstract.
With the analysis of simulation curve, it can be seen that the double-phase control strategy can greatly improve handling and stability at high speed and flexibility at low speed, which provides a theoretical basis for multi-axle vehicle safety.

Introduction Tunnel is often used in many fields such as mining engineering, hydropower engineering, traffic engineering and national defense engineering.
Tunnels often need build lining to enhance their stability because of geologic conditions or other request of engineering, some tunnels need build steel lining, for example, in the hydropower tunnels construction, conveyance tunnel usually need build steel lining because it is pressure tunnel[2], it is key technology problem for engineering how to ensure the safety of underground chambers and lining under the acting of adjacent blasting construction, so there is important engineering significance for studying the stability of underground chambers and lining under the action of blasting vibration.

But as the traffic volume increasing, especially for heavy vehicles and overweight vehicles, the problems of fatigue damage and crack are highlighted, which is more prominent for orthotropic steel bridge decks.

If the web of U-rib is penetrated by the crack, the integer and safety of deck is not too dangerous due to the load redistribution induced by the change of the deck stiffness.

The significance of fatigue results especially from the economical point of view (costs for development of new materials, testing equipment’s, methods of testing of prototypes and final products etc.) and safety of people whose life also depends on the device working reliability [1 - 4].
It was also concluded that for application of dynamically stressed components in the traffic it is necessary to provide adequate surface corrosion protection to the pin.
