中文摘要:针对平头货车驾驶室无专用吸能区间和吸能元件的情况,由理论分析提出通过驾驶室各部件吸能量重新分配来改进驾驶室耐撞性的方法。参照ECE R29法规,以有限元法仿真某款实车驾驶室的摆锤碰撞过程,通过改变驾驶室部件的厚度尺寸来分配部件吸能量,评比碰撞后驾驶室生存空间,研究驾驶室生存空间与主要部件吸能量之间的关系,并依据分析结果提出切实可行的改进方案,进行实验验证。研究结果表明,适当增加或减少各部件的吸能量,达到吸能量的合理分配,可有效改进驾驶室耐撞性。

Abstract:Aiming at the lack of specific energy absorption area and components for flat truck cab, a method for improving the cab’s crashworthiness was proposed, which was realized by reallocating the power dissipation of each component. Referring to rule ECE R29, finite element method was used to simulate the pendulum collision process of some real vehicle to distribute the power dissipation by changing the thickness of components of cab. Living space of the cab after collision was evaluated to analyze the relationship between it and power dissipation, and experiment was carried out based on the analysis result to give some reasonable instruction. The analysis result showed that an appropriate increasing or decreasing of power dissipation of each component could optimize the crashworthiness of cab effectively. 

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.
