Dynamic and Static Strain Testing and Analysis System

Overview:
The RHA-TST3830 dynamic and static strain testing and analysis system is designed specifically for high-speed strain measurement, with a maximum sampling frequency of 100Hz. This system is widely used in various testing sites such as bridge dynamic and static load tests, pseudo dynamic tests, fatigue tests, etc. It can collect various physical quantities such as stress-strain, voltage, displacement, temperature, etc., and is widely used by many universities and research and testing institutions in China.
Application scope:
1. According to the measurement plan, complete the measurement and analysis of dynamic and static strain stress in 1/4 bridge (three wire system, common compensation), half bridge, and full bridge states;
2. Equipped with various bridge sensors, it can measure and analyze various physical quantities such as pressure, force, load, displacement, etc;
3. Equipped with thermocouples, temperature measurement and analysis can be achieved;
4. Paired with TST126, it can achieve modal analysis of large-scale structural experiments.
3、 Software functions
A sampling control and analysis software developed using Vc++in the Chinese Windows 2000/XP/Vista/7 operating system, which has strong real-time performance, as well as good portability, scalability, and upgradability;
2. Enter the elastic modulus and Poisson's ratio of the tested material, and the software will complete the calculation of stress and the principal stress and direction of strain flowers such as two right angles/three 45 ° right angles, 60 ° equilateral triangles/umbrellas, sectors, etc;
3. Complete the unit of the measured physical quantity based on the output sensitivity of the sensor; Normalization of dimensions, directly displaying the measured physical quantity; The computer automatically completes the control of balance and trial sampling, and defines the measurement data of two optional measuring points as the X-axis and Y-axis, drawing curves while sampling, and completing the function of an X-Y recorder (hysteresis curve);
To prevent data loss, prioritize saving data based on the sampling time. The management of data includes functions such as opening files, backing up data, deleting files, and converting data formats (TXT, MAT, EXCEL), ensuring convenient and reliable data processing.
