曲柄压力机床身动态应力的测量,通常采用动态电阻应变仪和光线示波器,整个实验过程和计算过程都比较繁琐,而且测量误差比较大。随着计算机科学的发展和微型计算机在锻压行业应用的不断普及,在曲柄压力机床身动态应力应变测试中,我们把TP801单板机和动态应变仪连接制成一实验装置,对曲柄压力机动态应力进行测量,实现了测量和数据处理自动化。这一实验装置可对曲柄压 Crank press machine dynamic stress measurement, usually using dynamic resistance strain gauge and light oscilloscope, the entire experimental process and the calculation process is more complicated, and the measurement error is relatively large. With the development of computer science and the ever-increasing popularity of microcomputers in the forging industry, in the dynamic stress-strain testing of crank press machine bed, we connected the TP801 single-board machine with the dynamic strain gauge into an experimental device, Stress is measured and measurements and data processing are automated. This experimental device can crank the pressure
