After receiving the nc repertoire computed by nc module , and further computation processing in the servo - control module , it will supply the driver signals of the pmsm through the real - time feedback information from the current loop , the speed loop and the position loop , 3 closed loops in all 伺服控制模块接收nc指令模块生成的nc指令后,通过电流环、速度环、位置环实时闭环反馈的指令信息,计算处理后,输出驱动电机需要的pwm信号。
Based on project example , the article presents the construction stress computation process of hydraulic creep form in the construction of high bridge pier , the construction stress analysis has applied successfully in the project practice and can be referred in the similar special structure construction 本文基于工程实例,给出了桥梁高墩身施工选用液压自爬模完整的施工受力计算过程,且已成功地应用于工程实践,可供类似特种结构施工参考。
In this article , the concept of statistical template based on data was firstly brought forward , which can effectively simulate the entire statistical computation process by recording the information of data structure and analytic method . we make the statistical template as theoretical basis of statistical analysis platform ( sap ) the statistical template can make our sap has the properties described as follow : 1 . good facility the requirement is to have the statistical knowledge , user need n ' t has any background of computer science and computational mathematics ; the time that is used to learn is short 本文通过对一般统计计算过程的分析,提出了以统计数据为中心的统计分析模板的概念,该概念以统计字段来描述统计数据的数据结构,通过记录统计数据结构信息及其相应的统计分析计算服务信息的形式在逻辑上有效地模拟了统计计算的全过程,从而为统计软件平台构建了一个坚实的理论基础,使该统计软件平台具备了以下特点: 1 、易于使用概念清晰、使用简便,作分析工作时使用者无需任何计算机科学和计算数学背景知识,懂得基本操作即可,学习周期短。
According to the computation process of the fem and assumption , associating of the fem mesh that have separated and the grouting stress diffusion equation , the integral stiffness matrix and the load matrix can be formatted , then the displacement of the nodal point can be got after solving the simultaneous linear equations . and then the grouting parameter can be computed and analyzed 然后,依据有限元法的计算步骤和所作的假设,结合已经离散化了的网格、灌浆压力扩散衰减公式,形成整体刚度矩阵、荷载矩阵,经求解后得到结点的位移,并依此计算分析灌浆参数。
