Mechanical principle and mechanical elements 机械原理与机械零件
With the development of high science & technology and precision theory , the influence of temperature on manufacturing and measuring accuracy of mechanical elements has been paid more and more attention to 随着现代高科技的发展和机械精度的迅速提高,温度对机械加工精度和测量精度的影响越来越大。
The time continuous mathematic models of typical control elements in the vehicle control system were developed by experiment , combining the time continuous mathematic models of traditional mechanical elements with that of typical electronic elements 用实验方法建立磁导航车体运动数字控制系统典型环节的时间连续数学模型,结合车体运动机械操纵环节的传统数学模型建立整个控制系统的时间连续数学模型。
The database technique has been widely used in such aspects as mater in database , the design of mechanical element and the device management . however , it has seldom been found using in evaluating fatigue life of metal structure , which is the focus this paper aims at 数据库技术在材料专用数据库、机械零件设计、设备管理等方面获得了广泛的应用,但将数据库技术应用于金属结构疲劳寿命评估却并不多见。
