摘要
声卡是PC中常见的声音信号采集硬件。介绍一种使用计算机声卡采集振动试验台的摆杆加速度信号;并对采集到的数据与仿真数据进行初步对比分析;以此来验证动力学仿真分析结果。此方法作为一种低成本的动力学模型仿真数据试验验证的解决方案,可广泛应用于教学实验课程。
Sound card, which is used to record sound waves, is one of the most common instruments in Personal Computer. A method to acquit signals of acceleration by the sound card is introduced, and then use the acquired data to compare with the data from the simulation of dynamics model is used for the validating. It＇s a much cheaper method to solve the validating the simulation of model in dynamics, and it can be useful in the experiment classes.
