Abstract: In order to improve the accuracy, efficiency and conveniency of the soil bin for test research of agricultural machinery, a new soil bin dynamic parameters measurement system was developed. The five-bar force measurement device was introduced to the system, which was consisted of pull-pressure sensor, angle sensor and three-point suspension and the test platform was carried out based on LABVIEW to realize real time measurement of forward speed, power take-off shaft speed and torque, output power, the frontal resistance of test object etc. Practical application demonstrated that the test system can work reliably and can improve working efficiency considerably.
