This paper starts from discussion of the social and political effects on truck design. Then the author reviews the future of truck design in technical as pects, stressing fuel economy. To improve fuel economy, the heat conversion efficiency of diesel engines must be first improved. The specific fuel consumption of current U. S. diesel engines is about 167 g per hp hr, the best is only 150 g. per hp. hr. The author predicts that 145 g per hp hr can be attained, if some new techniques now under development can be perfected and used in time during the next decade. Near term benefits can be obtained through research in lubricant to reduce frictional losses, and reducing accessories' power requirements, and supercharging intercooling, etc.Using radial tires, especially low profile wide singles, instead of conventional dual tires for the rear wheels will reduce truck rolling resistance and improve fuel economy 10-20%.Using cab top deflectors and improving the configuration of tractor's cab will reduce drag resistance 35% and improve fuel economy 15-17%。 So, in the next decade, with engine improvement of 100%, total fuel economy improvement of 47% can be obtained. Tractor-Semi-trailer combination with GCW of 36.3 T cruising on level road at 88 km/hr speed will have fuel consumption rate of 29.5 L/100 kmFor improvement in fuel economy, the regulations governing the GCWand length of truck trains must be and will be enlarged. The tare weight of trailers will also be reduced proportionally.

本文先从社会因素对货车设计的影响谈起。再讨论技术和结构方面的动向。作者认为今后货车的发展以节省燃油为主,方法是: 提高柴油机的热效率。目前美国柴油机每马力小时耗油量约为163克,最好的为150克。预期十年内随着现在处于发展阶段的技术完善之后,可望为145克。近期收益将从润滑油等的改进减少摩擦损失和附件驱动损火等和增压中冷中得到。 用子午线轮胎特别是后轮用宽断面单胎代替双胎可减少滚动阻力,节油10~20%。 用驾驶室顶部导流罩,改进驾驶室的外形等,可减少风阻35%,节油15~17%。 所以十年后如发动机节油10%,共可节油达47%。总重36.3吨的汽车列车在水平公路上以88公里/小时车速行驶时,耗油率将为29.5升/百公里。 为提高燃油经济性,提高汽车列车组合总重和列车长度是可能的和必要的。

Articulated Vehicles consisting of tractors and trailer are widely used to-day. Not only are they commonly used in general trucks and the articulated buses but also in automobiles and military motor vehicles with their Semi-trailers. This paper established the mathematical model of three degrees of freedom for the tractor and semi-trailer and derived some moving differential equations from it. Finally, through a practical example , we calculated with computer the steady response and the transient response. These results are in good agreement with the foreign ones.

由牵引车及半挂车组成的连接车辆已日益普及,它们不仅用于一般货车,铰接式公共汽车,也用于小客车拖带半挂车及军用车中.本文建立了牵引半挂车组成的连接车辆的三自由度数学模型,并推导出运动微分方程,进一步推导出稳态响应及瞬态响应公式.最后本文以实例计算了稳态响应及用龙格-库塔法在电子计算机上解出了国外车辆的瞬态响应与国外文献比较有相当好的一致性.
