压配式实心轮胎产品和系列标准简介

随着我国国民经济的发展，工业车辆获得高速度的增长，同时对轮胎规格品种的需求也日益增加，要求轮胎的承载能力高，轮胎尺寸小，从而导致在轮胎结构形式上也发生变化。80年代中期以前工业车辆基本使用充气轮胎，后应国内外市场需求，发展了与充气轮胎轮辋互换的实心轮胎，但近几年来国外工业先进国家又逐渐发展了品种规格繁多的压配式实心轮胎，以满足工业车辆的要求。为了适应国内叉车生产厂和使用单位配用这一类型轮胎的需要，国内轮胎制造厂近几年进行了一定规模的研制，生产了部分规格，积累一定的生产经验，并开始向国外出口产品。为…

Experimental study of tenability during a full‐scale motorcoach tire fire

Full‐scale fire experiments were conducted at the National Institute of Standards and Technology (NIST) to investigate tire fire interactions with the passenger compartment of a motorcoach. A single full‐scale experiment with a partially furnished interior was conducted to investigate tire fire growth within the passenger compartment and the onset of untenable conditions. A tire fire was initiated using a burner designed to imitate the frictional heating of hub and wheel metal caused by failed axle bearings, locked brakes, or dragged blown tires. Measurements of interior and exterior temperatures, interior heat flux, heat release rate, toxic gases, and visibility were performed. Standard and infrared videos and still photographs were also recorded. The results of this single experiment showed that after fire penetration into the passenger compartment, the tenability limits were reached within 8 minutes near the fire and within 11 minutes throughout the passenger compartment.

Experimental study on tire fire penetration into a motorcoach passenger compartment

Two full‐scale fire experiments were conducted to determine the mode of penetration of a tire fire into the passenger compartment of a motorcoach. A special burner was designed to imitate the frictional heating of hub and wheel metal caused by failed axle bearings, locked brakes, or dragged blown tires. For the first experiment, heating to obtain tire ignition was initiated on the exterior of the passenger side tag axle wheel and for the second, on the exterior of the passenger side drive axle wheel. Measurements of interior and exterior temperatures, interior heat flux, and heat release rate were performed. Standard and infrared videos and still photographs were recorded. Both experiments showed that the tire fires ignited the plastic fender and glass‐reinforced plastic exterior side panel (below the windows) upon which the fires spread quickly and penetrated the passenger compartment by breaking the windows. Measurements showed that other potential fire penetration routes (flooring and lavatory) lagged far behind the windows in heating and degradation. Copyright © 2012 John Wiley & Sons, Ltd.

Experimental study on hardening a motorcoach against tire fire penetration

Three full‐scale fire experiments were conducted to assess methods of hardening the motorcoach against penetration of a tire fire. The first method was to replace the combustible fender and exterior side panel above the wheels with stainless steel sheet metal. The second method was to coat the plastic fender and side panel with an intumescent layer. The third method was to install a sheet steel fire plume deflector between the fender and side panel. A special burner was used that imitates the frictional heating of hub and wheel metal caused by failed axle bearings, locked brakes, or dragged blown tires. For each experiment, heating to obtain tire ignition was initiated on the exterior of the passenger side tag axle wheel. Measurements of interior and exterior temperatures, interior heat flux, and heat release rate were performed. Standard and infrared videos and still photographs were recorded. The experimental results were compared with those obtained with no fire hardening. The metal replacement method performed best and prevented fire penetration for over 30 min longer than the nonhardened cases. The intumescent coating extended fire penetration by about 20 min longer than the nonhardened cases. The steel plume deflector had no significant impact on the timing for fire penetration of the windows. Published 2015.

新型子午斜交胎结构设计与力学性能研究

如今优越的承载性能、操控性能和安全性能成为了轮胎行业未来发展的主旋律,然而由于高扁平率的轮胎在使用过程中胎肩变形难以控制导致轮胎接地压力分布均匀性较差,从而影响轮胎的磨损性能和安全性能。基于子午胎和斜交胎的胎体结构和性能对比,提出了一种新型的子午斜交胎体结构,利用有限元软件ABAQUS建立子午斜交胎的三维有限元模型,并对其进行接地性能和骨架材料力学性能分析。研究结果表明,子午斜交胎体结构通过提高胎侧刚性和控制胎肩变形,减小了胎肩的应力集中,改善了轮胎接地压力分布均匀性,避免了轮胎断面轮廓畸变,提高了轮胎的承载性能、耐磨性能和操控性能。
