摘要
介绍了1套动态参量综合测试实验装置,可作为真实机械的信号源,为数据采集和分析提供多种实测动态参量。该装置内置3个桥式电阻应变传感器,可实现动态位移、弯矩与扭矩的信号转换。装置动力设计合理,选用了直流牙嵌式电磁离合器,采用偏心轮及悬臂梁结构,用箔式应变片和应变花测量动应变。该装置设计合理可靠,操作简便,可以满足多学科、多层次、综合型、设计型实验教学的需要,可作为一项具有创新意义的实验技术研究成果推广应用。
This paper develops a set of integrated experiment equipment,which can arise many kinds of dynamic signals for data sampling and analyzing.It can meet the need of multi-subjects,multi-levels,integrated and designed experiment teaching,with reasonable structure and convenient operation.This device includes three bridged resistance strain sensors,which are used to transform the signals of dynamic displacement,bend and distortion to electrical signals.It is designed with rational drives,with the application of direct-current electromagnetic clutch,eccentric wheel and the structure of cantilever girder,stuck strain foil to measure dynamic strain.
