摘　　要：转向双摇臂机构的运动协调性直接影响双前桥重型汽车的行驶性能,因此对其转向双摇臂机构的优化设计具有重要意义。文章介绍了重型汽车转向双摇臂机构的转向原理,用空间几何方法建立了双摇臂机构优化设计的数学模型,并用MATLAB软件优化工具箱中的优化计算函数来编制程序,对双摇臂机构参数进行了优化,使转向双摇臂机构的性能得到显著提高。Unisonous movement of double rocking arms steering mechanisms will directly influence the steering performance, so optimization design of the mechanism is significant for double-front-axle heavy trucks. In this paper, the steering principles of double-front-axle heavy trucks are introduced, the mathematic model for optimization design of double rocking arms mechanisms is established by the space geometry method,and the program of optimization of the mechanism＇ s parameters is compiled by using the functions in the optimization toolbox in the MATLAB software. As a result, the mechanism＇s performance is improved prominently.
