【摘要】 介绍了利用LabVIEW开发的角速度角加速度测试仪,详细分析了此虚拟测试仪器的硬件、软件的实现原理。该虚拟仪器能够与实验室里传统的JC-83型角速度角加速度测定仪的部分硬件配合使用,成为新型的机械原理课程教学实验仪器。通过对四杆机构进行了实际的角速度角加速度测试实验,证明了该虚拟仪器具有传统仪器无法比拟的优势,能使传统仪器具有新的利用价值。该虚拟仪器灵活性好,能够根据需要移植应用到其他的测试场合。更多还原

【Abstract】 A virtual instrument for measuring angular velocity and angular acceleration based on LabVIEW was introduced.The principle of hardware and software about the virtual instument was analysed in detail.The virtual instrument can be used in the teaching experiment of the course of mechanical principle through the cooperation with the traditional instrument,JC-83 instrument for measuring angular velocity and angular acceleration.The actual experiment for measuring angular velocity and angular acceleration had been made in the 4-bar mechanism,which proved the superiority of the virtual instrument to the traditional instrument,and that the improvement can be made in the traditional instrument.There is a good flexibility in the virtual instrument,which can also be applied in other measurement occasion according to the practical requirement.更多还原
