| 摘 要： | 计算机声卡在虚拟仪器开发中拥有广大的应用前景。以LabVIEW为软件开发环境,以普通PC机的声卡代替价格昂贵的商用数据采集卡,设计实现了一个简单的摩擦噪声测试分析系统。该系统可正确采集声卡设计频率范围内信号,可以实现摩擦噪声的采集分析功能。基于声卡的数据采集与分析的廉价方案,可以推广到环境噪声分析、声压检测和实验室测量等多种领域。

| Abstract: | PC sound card has broad application prospects in virtual instrument development.A simple measurement and analysis system for friction-induced noise was designed and realized with LabVIEW as software development environment and with general PC sound card taking the place of expensive commercial data acquisition card.This system could acquire signals in the audio frequency rang designed for sound card accurately,and it also could acquire and analyze friction-induced noise.Thus,the cheap data acquisition and analysis solution based on sound card can be extended to those fields such as ambient noise analysis,sound pressure test and laboratory measurement etc. |
