中小功事内燃机CAD课题演试会于1987年10月20～24日在上海召开。该课题是由上海内燃机研究所负责,有许多高校和研究所协作进行的重点科技攻关项目。在强调基础理论研究的同时,特别注重实用性,要为生产服务。在这次演试会上,共作了专题报告20篇,进行了实际上机演示并参观了课题展览厅。从进展情况看,课题完成后有如下应用功能:(1)进行整机总布置方案设计;(2)为新机系列设计及旧机扩展变型提供各种方案对比;(3)进行新机性能预测、工作过程循环模拟;对老产品通过实时数据采集及专项试验进行性能的分析、评定,提出改进措施;(4)进行零部件的设计(参数型或交互型),给出工程设计图纸,承接内燃机老产品改进;(5)对内燃机润滑系统和配气机构进行故障诊断;(6)完成有关专题的工程分析计算,由计算机提交计算报告书(包括中英文文字、曲线);(7)以常用算法库、材料机械性能库、内燃机整机性能和零部件结构数据库和图库、优化方法库等为用户服务,如提供国外样机零件结构形状和尺寸,(8)提
Small and medium-sized internal combustion engine CAD task show in October 1987 October 20 to 24 held in Shanghai. The subject is responsible for the Shanghai Internal Combustion Engine Research Institute, there are many key scientific and technological projects in collaboration with universities and research institutes. While emphasizing basic theoretical research, we pay special attention to practicality and serve for production. In this performance, a total of 20 thematic reports were made and the actual demonstration was given and the subject exhibition hall was visited. From the progress of the situation, after the completion of the project has the following application functions: (1) the total layout of the machine design; (2) for the new machine series design and the old machine variant to provide a variety of program comparison; (3) the performance of the new machine Forecasting and working process cycle simulation; analyzing and assessing the performance of old products through real-time data collection and special tests; (4) carrying out the design of parts (parametric or interactive), providing engineering design drawings, (5) Perform troubleshooting on internal combustion engine lubrication system and valve train; (6) Complete project analysis and calculation of relevant topics and submit calculation report (including Chinese and English texts and curves) by computer; (7) To the common algorithm library, mechanical properties of the material library, internal combustion engine performance and parts structure database and library, optimization method library for users, such as the provision of foreign prototype parts shape and size, (8) to mention
