以软件ADAMS为平台,用Pro/E三维软件建立车箱模型导入ADAMS,在ADAMS创建倾翻车倾翻机构模型,箱体的倾翻机构为液压缸连杆机构,箱体的最大倾翻角为45°,当倾翻到45°时箱门箱盖自动打开,箱门箱盖倾翻机构为由液压缸驱动的联动四连杆机构。分析得到了箱门的角速度、角加速度、加速度曲线图以及倾翻机构连接点处的受力图等。以箱门受力最大值达到最小为目标函数对模型各设计变量进行分析,找出了对目标影响最大的变量,通过优化确定模型的最佳结构,优化结果使得箱门受力最大值降低。
Using software ADAMS as a platform, the vehicle model was built with Pro / E 3D software and imported into ADAMS. The tilting mechanism model of rollover vehicle was created in ADAMS. The tilting mechanism of the box was hydraulic cylinder connecting rod mechanism. The maximum tilting angle of the box was 45 °, When tipping to 45 °, the door of the door opens automatically, and the tipping mechanism of the door and door cover is a linkage four-bar linkage driven by the hydraulic cylinder. The angular velocity, angular acceleration, acceleration curve of the box door and force map at the connection point of the tilting mechanism are obtained through analysis. In order to minimize the maximum force of box door, the design variables of the model were analyzed to find out the variables that have the greatest impact on the target. The optimal structure of the model was optimized and the maximum value of the box door was reduced.
