针对当前汽车动力学仿真软件建模复杂度高、模型结构不易理解、模板开放性不高等缺点,提出开放的模板化建模技术.将汽车动力学模型分解为相对独立的子系统并抽象为基本模板,采用“基本模板—结构模板—模板实例化”的架构,用XML描述模板,从而实现模板的开放性,构建汽车动力学模型的树状层级模板库和实例库,结合基于实例推理的方法生成模型.在此基础上开发了汽车整车建模软件,并以某重型汽车起重机为例说明了该技术的应用.%In view of the disadvantages of the current vehicle dynamics simulation software in terms of high complexity and low readability, an open template-based modeling technique for vehicle dynamics simulation is proposed The vehicle dynamic models are divided into some relatively independent subsystems which are then abstracted as basic templates. The "basic template-structure template-template instantiation" architecture is used. The template is described by XML to realize the openness of the template. The template base and case base are established using tree structure. The model instance is generated by the case-based reasoning (CBR) method. On this basis, a vehicle dynamics simulation modeling software is developed and a heavy truck crane is built as an example to illustrate the application of the technology.
