基于Windows的冲击谱试验机测试分析系统的研制

目的考核产品的耐冲击能力，为冲击谱试验机研制一套测试分析系统。方法 系统由加速度传感器、信号适调仪、低通滤波器、数据采集板和配有测试分析软件的微机构成。结果：系统能对8路冲击加速信号进行实时数据采集、分析，完成对分析结果的显示、打印、保存任务，通过与美国SD2250B振动控制和分析系统进行比较测试，证实测试系统误差低于3．5％。结论 系统具有精确度高、可靠性强、人机界面友好等特点，可用于瞬态信号的测试分析。

An Analysis and Measurement System Based on Windows 98 for Use with Shock Spectrum Testing Machine.

Objective An analysis and measurement system was developed for use with shock spectrum testing machine for testing spaceflight products. Method The system is composed of an accelerometer, a signal conditioner, a low pass filter, a data acquisition card and a personal computer with analysis & measurement software. Result The system is employed not only to sample and analyze 8 channels of the shock signals, but also to display, print and save/review the results of analysis. Comparing with SD2550B Vibration Control and Analysis System, this system ,s error ratio was proved to be less 3.5%. Conclusion The system was proved to have achieved a high precision and reliability.It has friendly man machine interface.It can be used for measuring and analyzing transient signals.
