coons surface造句
例句与造句
- As a part of the civil 863 plans , two multiple - contact models for two kinds of braking system are built in the paper , in which contact fields are described as coons surfaces , initial velocity is programmed in fortran . the thermal - mechanical coupling braking processes are simulated for the first time by msc . marc , the general - used nonlinear fem software . time distributions of the velocity , the stress and the temperature of the components under various initial velocity and brake force are obtained , which offer theoretic gist to study the life of the wheel , the disc and so on
作为国家行业863重大课题《铁路机车车辆虚拟样机系统》的一部分，本文在研究接触问题和热?机耦合问题数值方法的基础上，采用国际上通用的非线性有限元分析软件msc . marc建立了踏面制动和盘形制动主要部件的多体接触计算模型，其中用解析方法描述，即用nurb曲线、高斯曲面来描述接触区域，用fortran语言编写定义初速度的用户子程序，首次对两种制动过程热?机耦合进行了数值仿真，定量给出了主要制动部件在不同初速度、不同制动力下各个时刻的速度、应力和温度的变化规律，为研究车轮、闸瓦以及制动盘寿命提供了理论依据。 - The significance established the system is to generalize the theories and methods of bi - cubic coons surfaces and to simplify the boundary conditions greatly which can are directly derived from the given interpolating data . hence the difficulty of determining boundary conditions of multivariate spline is overcome , which makes it use in many applications . 2
