A Study on Centroid Safety Area and Ultimate Load of Heavy-duty Vehicle

高速化和重载化的公路交通发展方向,对重载车辆的行驶平顺性、操纵稳定性与安全性提出了更高的要求。车辆的加载重心的位置是重型载重车辆行驶的关键因素,针对某型载重车辆,分析求解了某车型的等效支撑位置、重心的完全计算方法研究了质心安全区域,然后介绍了极限载荷分析的计算方法与加载质心安全区域的软件实现。通过某型载重车辆的设计来分析其质心安全区域与极限载荷,对加载重心的安全区域提供了一种新的方法与思路,旨在为后续车辆运动学的相关研究打下基础。

The direction of fast-speed and heavy-duty highway transportation imposes demanding requirements for smooth driving, stabile operation and safety of heavy-duty vehicles. The position of the loading center of gravity is the key factor affecting heavy-duty vehicles' driving. For a certain type of heavy-duty vehicle, its equivalent support position and center of gravity is analyzed and determined through the complete calculation method, and its centroid safety area is studied. Then the calculation method for ultimate load analysis and the software realization of the safety area of the loading centroid are introduced. Through analyses of the centroid safety area and the ultimate load of a certain type of heavy-duty vehicle, we offer a new method and idea for the follow-up study of vehicle kinematics.
