利用切削功率进行切削过程监控及自适应控制的成功策略是以正确认识实测功率信号、机械系统、刀具状态以及各种程过参数如主轴转速、进给率、切削深度等之间关系为基础的。本文将建立铣削加工程过中主轴驱动交流异步电动机的输入功率模型以便为这些关系打下基础。该模型通过仿真和试验进行了验证。车辆动力学分析模拟──建模理论与工程应用居乃俊(中国兵器工业计算机应用技术研究所北京100081)摘要──介绍了一种称为VDAS(车辆动力学分析模拟)的计算机软件。该软件建立在军用车辆三维动态系统数学模型基础上,采用统计模拟法产生系统随机激励──双侧路面不平度,面向系统状态方程求解系统响应时间序列,并给出了概率统计和性能评价结果。大型泵站进水流道内流场的水力计算和测量关醒凡陈红勋谢达荣郭乃龙(江苏理工大学镇江212013)摘要──对大型泵站进水流道内部流动进行分析后,提出了势流假定下的大型泵站进水流道内部流动的全三维直接边界元的解析方法,并计对30°斜轴泵站进水流道的初步设计方案进行了计算和试验验证。分析表明,计算方法是可行的和可信的。刀具表面覆盖膜形成机理研究郝春水张东石赓儒田春芳(东北大学沈阳110006)摘要──研究了切削Ca-S易?
The successful strategy for cutting process monitoring and adaptive control with cutting power is based on a correct understanding of the measured power signals, the mechanical system, the status of the tool, and the relationships among the parameters that have passed, such as spindle speed, feedrate, depth of cut, etc. . This article will establish the input-power model for milling through the mid-spindle driven AC induction motors in order to lay the groundwork for these relationships. The model is verified by simulation and experiment. Simulation of Vehicle Dynamics - Modeling Theory and Engineering Application JU Naijun (Institute of Computer Application Technology, China Ordnance Industry Press, Beijing 100081) Abstract - This paper presents a computer software called VDAS (Vehicle Dynamics Analysis Simulation). Based on the mathematical model of three-dimensional dynamic system of military vehicles, this software generates the system random stimulus ─ ─ two-sided road surface roughness using the statistical simulation method and the system response time series for the system state equation, and gives the results of probability statistics and performance evaluation . Hydraulic Calculation and Measurement of Flow Field in Intake Passage of Large Pumping Station Guan Xingfan, Chen Hongxun, Xie Darong, Guo Nailong (Jiangsu University of Science and Technology, Zhenjiang 212013) Abstract: After analyzing the internal flow in the inlet channel of large pumping station, a large pumping station The analysis method of the full three-dimensional direct boundary element flowing inside the inflow channel was calculated and the preliminary design scheme of inflow channel of 30 ° inclined axis pump station was calculated and tested. The analysis shows that the calculation method is feasible and credible.
