Development and Application of Engineering Vehicle Transmission Load Test System
Transmission load was one of the important parameters for engineering vehicle powertrain system, on the basis of calculating drive shaft torque values and ascertaining the measurement point positions, we selected resistance strain guages to design torque sensors and also chose a signal telemetry system, after using a self-made torque calibration bench to statically calibrate torque sensors, we developed a test system for loader drive shaft load. According to the given test program, we performed an actual loader experiment to measure torque at the loader drive shaft measurement points and analyzed the test waveforms. The results of bench calibration and actual loader test showed that the designed torque sensors had a high sensitivity and a good linearity, and the developed test system was correct and effective.
