中文摘要:阐述了后轮驱动及四轮驱动两种驱动方式下可变直径轮全地形车辆的越障性能。首先在RecurdynV7R5软件中建立可变直径轮与普通轮胎模型,并对其越障特性进行了分析。以此为基础建立了后驱及四驱车辆前后轮径变化对越障性能影响的力学模型,进行了理论计算,结果表明车辆驱动方式以及车辆轮径的变化对车辆的越障性能具有很大影响。又在RecurdynV7R5软件中建立了后驱及四驱2种驱动方式下的整车模型,调整车轮直径模拟分析其越障性能,并与理论计算进行了对比。最后,实验验证了理论计算与仿真分析的结果是可信的。

Abstract:The obstacle climbing performance was discussed for variable diameter wheel all-terrain-vehicle (ATV) with two kinds of drive mode: rear wheel drive mode and four-wheel drive mode. In RecurdynV7R5 software models of the diameter-variable wheel and a normal tire were built to analyze the climbing obstacles characteristics. On this basis, the vehicle model which would be driven by rear wheel or four wheels mechanical was set up, and the calculation was executed. The results showed that the driving way and the variation of wheel diameter play an important role for obstacle climbing performance. In RecurdynV7R5 software the whole vehicle model with rear wheel drive mode or four wheel drive mode was built, and obstacle climbing performance was simulated in the condition of adjusting the wheel diameter size. Then, the calculation and the simulation were compared. In the end, experimental results verify the reliability between the theoretical calculation and the simulation analysis.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
