机床液压管道三维自动布线系统开发
The Development of a 3D Automatic system for hydraulic pipelines on machine tools

液压管道的布置是液压系统设计中重要的一环。对于装配体模型复杂的机床而言，传统的手动布线方法需要耗费较多的时间及人力，而三维设计软件中自带的三维自动布线模块尚存在操作繁琐、造型不直观、通用性不强等缺点。据此，本文针对机床的液压管路布置开发了一套三维自动布线系统，系统以三维设计软件SolidWorks为开发平台，利用VB.NET作为开发环境，应用二次开发原理以及数据库技术，实现了管路零件模型的参数化设计；在寻径算法上结合动态规划及A-STAR算法并加以改进，实现了管路的智能化布置，同时能够统计管线用料数据并生成明细表。系统操作简单，减小了设计工作量，缩短了设计周期。
The layout of hydraulic pipelines is an important step in the design of a hydraulic system.For machine tools which have a complicated assembly model, manual routing takes a lot of time. But there still exist some problems in the automatic routing module in three-dimensional design software. Those modules are not universal and the shapes are nonintuitive. Besides, the system are not easy to operate. To solve those problems, a 3D Automatic system for hydraulic pipelines on machine tools is developed. By using SolidWorks platform and VB.NET environment, the parametric design for models of pipeline spare parts is implemented based on secondary development principles and database technology. The intelligence layout for pipelines is implemented by using dynamic programming method and A-Star algorithm. Besides, a table is provided in the program to present the data for length of pipelines. The program is easy to operate, which effectively decrease workload for designing and shorten the design cycle
