拼装式组合式平板车(简称平板车)是一种车轴多、全部车轮均参与转向的多轴挂车。通过对平板车转向机构的分析,得到了转向机构各构件之间的运动学关系,建立转向机构的优化模型。应用复合形优化算法对建立的优化模型进行优化求解,使用Lab VIEW语言编写了相应的优化程序,计算出各构件的初步尺寸。模型建立后,使用ADAMS软件对其进行仿真优化并分析,分析结果证明,优化后的平板车模型转向机构的目标函数值优于借用优化程序初步计算时的模型的目标函数值。
Assembled combined flatbed (referred to as the flatbed) is a multi-axle, all the wheels are involved in the steering multi-axis trailer. Through the analysis of the steering mechanism of the flatbed vehicle, the kinematics relationship between the components of the steering mechanism is obtained, and the optimization model of the steering mechanism is established. The complex optimization algorithm is used to optimize the model. The optimization program is written using Lab VIEW language and the initial size of each component is calculated. After the model is established, it is simulated and optimized by ADAMS software. The analysis results show that the objective function value of the optimized steering system of the flatbed model is better than the objective function value of the model when preliminary optimization is used.
