摘要
基于数字模型参数化建模方法及虚拟装配技术开发了DTⅡ型带式输送机数字样机系统。该系统能够根据总体设计要求及参数选型方式快速建立各类DTⅡ型带式输送机数字模型。系统工作原理是根据输送机的结构特征及功能,将输送机分为头架、尾架、中间架、托辊以及辅助设备等几部分。每部分的典型零件通过电子表格的数据进行参数化尺寸驱动,实现零件的实例化。最后调用装配指令将所有实例零部件总体装配起来,完成数字样机的建模工作。这种建模方法便于编辑和修改模型,节约时间和成本,大大提高效率。可以用于设计验证、分析、论证。为产品设计打下牢固基础。
Based on the parametric modeling method of digital model and virtual assembly technology,the digital prototype system of DTⅡbelt conveyor was developed.The system can quickly establish digital models of various DTⅡbelt conveyors according to the overall design requirements and parameter selection methods.The working principle of the system is to divide the conveyor into headstock,tailstock,middle frame,idler rollers and auxiliary equipment according to its structural features and functions.The typical parts of each part are parametrically driven by the data of the spreadsheet to realize the instantiation of the parts.Finally,the assembly instructions are called to assemble all the instance parts as a whole to complete the modeling work of the digital prototype.This modeling method is easy to edit and modify the model,save time and cost,and greatly improve efficiency.It can be used for design verification,analysis and demonstration.Lay a solid foundation for product design.
