摘　　要：为方便、准确地测试汽车安全带卷簧的扭矩性能,以高性能数据采集卡PCI-8602为核心开发了系统硬件;以VC6.0为开发环境,采用MFC多文档-视图结构和多线程技术设计了人机交互、数据采集与控制等软件功能模块;对软件功能和系统精度进行了实测。结果表明,测试精度达到0.001 N.m;测试系统满足汽车安全带卷簧扭矩测试的要求。To test torque performance of coil spring on car seat belt correctly and conveniently, system hardware is developed based on high performance data acquisition card of PCI-8602. Software function modules which include interactive module, data acquisition and control module etc., are developed with technique of document-view architecture based on MFC and multithreading technique in VC6.0 development environments. At last, software function and system precision are tested. The test results show that precision of torque test system is up to 0.001 N-m. The developed software satisfy test requirement of coil spring of ear seat belt,
