Application of DC Electric Dynamometer in the PTO Power Test of Tractors

摘要

Test of bench performance to the power of tractor PTO (power take-off ) is a necessary way to evaluate the economic and dynamic performance. So the bracket of engine bench testing is essential equipment, and the effect of DC electric dynamometer used in PTO power test is investigated in this paper. Realizing the process to achieve automatic control and automatic recording, thus greatly reducing the labor intensity of testing personnel and the human error in the testing process, but also greatly increased the accuracy of the test results.
