摘要： 提出带有机械电子元件的车辆底盘的优化设计方法和工具。为此，开发了一种转换软件，使得ADAMS/Car的多体系统（MKS）车辆模型能够自动转换到软件工具alaska中，随后，转换成的车辆模型通过轮胎模型、驾驶员模型和机械电子操纵装置模型加以扩展，整个系统符号化的模型方程由alaska生成，并且以C代码形式输出。进行了车辆动力学评价准则的分析，为以性能准则（目标函数）和附加准则（约束函数）的形式进行多目标优化作好准备。讨论了各种灵敏度分析方法，自动微分被作为一种符号化方法的有用工具引入。对不同的优化方法进行了试验和对比，优化计算在工作站集群的通讯传输系统MPI支持下并行运行。所开发方法和工具的效率已在实际应用案例中得到体现。
Abstract: In this work, methods and tools for the Optimization Design of chassis with mechatronic components are presented. A new kind of software, allowing automatic conversion from multi-body vehicle models in ADAM/Car to those in Alaska, is developed. The converted vehicle model is extended afterwards through tire model, driver model and electromechanical steering system. The motion equation of the whole system is generated in symbolic form and output in C-code. Evaluation criteria for vehicle dynamics is analyzed, which makes preparation for the multi objective optimization in form of objective functions and constraint functions. In addition, different approaches of sensitivity analysis are discussed. As a useful tool for symbolic approach, automatic differentiations are applied. Test and contrast between different optimization methods are conducted. Optimization computations are completed in parallel with the support of Message Passing system MPI on a workstation cluster. The efficiency of the developed methods and toos has been presented in practical applications.
