Abstract: To overcome the shortcomings of the traditional manual stretching stress relaxation testing machine for the steel wire, a scheme of automatic control system with ADAM modules was proposed. The program compiled by Visual Basic programming language on IPC controlled the whole test process and recorded test data automatically. For the test data analysis, the extrapolating method of single- and dual-logarithm based on the least squares was adopted. Test results show that the system in the paper could control and monitor the test process automatically and record the test data timely. The test data could be extrapolated to reflect the steel wire stretching stress relaxation performance accurately.
