Based on msc / nastran software , by using of pcl language ( patran command language ) , new software of optimum design module was secondly developed for sectional optimization of plate and shell structures 在msc / nastran基础上,利用msc / patran提供的pcl语言,对板壳结构的截面优化的优化模块进行了二次开发。
The sectional optimization theory of membrane structure under size , stress and displacement constraints is developed . a special optimization module is developed by using pcl language of msc . patran 发展了膜结构在尺寸、应力和位移约束下的截面优化理论,并利用msc . patran提供的pcl语言,开发了专用的优化模块。
In this paper , optimization modules mentioned above are all carried out in nastran by using of pcl language . and several numerical examples are used to testify the program credibility and validity 本文利用pcl语言对上述优化模块在nastran上进行了程序实现,多个算例验证了程序具有合理性、精确性和收敛速度快等特点。
The development of shape optimization module on msc . patran is implemented on the base of pcl language . furthermore , the function of shape optimization for two - dimension continuum structures is augmented 本文使用msc . pcl语言在msc . patran & nastran平台上实现了优化模块的二次开发,增加了二维连续体结构形状优化的功能。
The surface of the pcl / pvc banded spherulites presented to be concentric periodic ups and downs . the period of the bands corresponded to the extinction rings under the polarized optical microscopy observation Pcl环带球晶的表面由周期性高低起伏的环状结构组成,其凸凹起伏的环带与球晶在偏光显微镜下的明暗交替相对应。
G . leaf s round wears away from the is small , maintained conveniently ; the working noise is lower than 75 decibels and dust pollution is little . vertical impactiong crusher . pcl - impact crusher . sand - making machines 该系列制沙机又俗称为自击式破碎机石打石破碎机八马克制砂机八马克冲击式破碎机,立轴式破碎机,立式冲击破等。
The paper analyzed the function of pcl - 832 card . in order to compensate the error , the program of interpolation directly modify the error , contain the library of pcl - 832 card and program of servomotor 本文分析了此卡的实现功能,并在插补算法程序中直接修正位置偏差,直接调用控制卡的程序库和伺服电机的驱动程序,实现了位置偏差的补偿。
It also solves technical difficult problems about continuing data acquisition , data stream storage , multi - thread , digital filter , query data and waveform display etc . . . in addition , it studies a supervisory method on monitoring work - state of twelve relays 本章还对用pcl一730数字fo卡监测十二个继电器的原理方法进行了研究,并给出了自检程序界面。
It has the functions of collecting vibration signal power spectruiru cepstrum and transfer function analysis and so on with the pcl _ 1800 . at the same time , the system can convert the data into the corresponding graph 本系统是windows界面下的状态监测与故障诊断系统,它在数据采集卡pcl1800的支持下,可以完成振动信号的数据采集以及功率谱、倒谱、谱阵和相干函数分析等功能。
Time and space consistency of the simulation nodes . besides , this dissertation develops the hardware card ( evoc pcl 720 ) and designs the vxds . it also provides the solution for the linking between the dis and hardware - in - the - loop simulation system 同时,论文进行了硬件板卡pcl - 720的开发和中断驱动程序( vxd )的设计,初步解决了分布交互仿真系统与半实物仿真系统的连接问题。
