摘要
针对当前内燃机行业对高精度扭振测试设备的需求,结合现有传感器技术、单片机开发以及信号处理技术,充分利用微机的高效处理能力,采用硬件高频计数测时原理,开发研制了内燃机曲轴轴系高精度扭振数字化测试系统。
On the base of technology of sensor,SCM(Single Chip Micyoco), DSP(Digital Signal Processing) and microcomputer, adopting the principle to measure time through high frequency counter, the precise digital torsional vibration test system of internal-combustion engine has been studied and developed for the requirement of current internal combustion engine industry in this paper.
