Abstract

In order to reduce the traffic accident acused by roller, this study finds out the breakthrough point from the cause-effect relationship and function achievement mechanism aspects and studies key technologies based on the bus rollover security. The research directions mainly include lowering the height of the mass center to the greatest extent, shortening the span between side windows or making improvements on the sectional dimension of side pillars, strengthening the soldering joints of side body, ensuring the continuity of close loop structures and employing high-strength steels. Research results demonstrate that the proposed improvement directions and measures designed to enhance bus rollover security are rational and effective and they can provide beneficial guidance and reference for security design in the bus manufacturing.
