液压挖掘机的计算机辅助设计在国内外已有大约20年的发展史,近10年发展特别迅速。我国在这领域的研究重点是工作装置CAD,其中在优化设计和有限元两个方面取得了较好的成果。浙江大学机械系冯培恩教授从1976年开始研究液压挖掘机反铲装置的
Computer-aided design of hydraulic excavators has a history of about 20 years at home and abroad. The development of hydraulic excavators has been particularly rapid in recent 10 years. Our country’s research focus in this field is the CAD of working equipment, in which two aspects of optimization design and finite element have achieved good results. Professor Feng Peien from Mechanical Department of Zhejiang University began to study backhoe of hydraulic excavator from 1976
