基于802S系统数控实训设备的研制

数控维修高技能人才的培养离不开专业的实验设备,因此开发具有自身特点、实用的实验台就有很现实的意义。本文以一种简易型数控维修设备开发为例,从开发思路、电气控制设计等多方面进行了经验论述,希望能为从事数控维修教学人员和实验设备研发人员提供借鉴。

基于DSP的数模混合视频传输开放实验设计

该文针对现有数字视频无线传输实验平台的不足,提出了一种基于数字信号处理器的数模混合视频编码传输开放实验系统。首先,介绍了该开放实验系统的整体结构及软硬件划分方案;其次,对硬件设计中数字信号处理器核、直接存储访问传输和跨时钟域数据传输等方面进行了详细阐述;然后,设计了相应的软件并对测试结果做了定量分析;最后,列举说明了该系统在教学实践中的应用。实践证明该实验系统能满足无线视频传输开放实验的需要,并取得了良好的教学效果。

Experimental investigation of key parameters pertinent to multi-hole orifice throttling characteristic

This study firstly defines a set of arrangement rule for perforated holes of multi-hole orifice(MO), and then presents three critical geometrical parameters including total number of performated hole, equivalent diameter ratio and distribution density of perforated holes, which are to quantify MO structure. This paper built the throttling test apparatus for nice test MO plates, which were designed according to orthogonal theory. The experiments were conducted to investigate the effect of three critical geometerical parameters on the pressure loss coefficient of test MOs. Results show that equivalent diameter ratio is the dominant prameter affecting MO throttling characterstic.
