0引言长期以来,我国农业装备行业采用技术引进、跟踪模仿的发展模式,缺少对各类产品技术的应用机理、设计理论的研究,难以掌握核心技术,原创性技术匮乏。重大产品开发尚停留在经验设计阶段,新产品开发周期长达24~36个月,比国外先进企业长1倍;新产品技术产业化转化时间长达3年以上;产品可靠性考核仍以田间试验为主,产品的可靠性设计技术应用尚属空白,严重 0 Introduction For a long time, China’s agricultural equipment industry has introduced the technology and followed the mode of development of imitation. It lacks of the research on application mechanism and design theory of various product technologies. It is difficult to grasp the core technology and the lack of original technology. Major product development still stays in the experience design stage, the new product development cycle is as long as 24 to 36 months, which is 1 times longer than that of foreign advanced enterprises; the conversion time of new product technology industrialization lasts more than 3 years; the product reliability assessment still takes field Test-based, product reliability design technology is still blank, serious
