Development of loader scooping performance test platform oriented to the work process

This paper developed a loader scooping performance test platform to obtain basic data on the performance parameters of the scooping process for the study of loader energy-saving technology from the optimization of the working process. Firstly, the test methods of scoop trajectory and bucket insertion angle, operation resistance, energy consumption of loader systems, scoop full bucket coefficient, and other parameters are studied. Then, based on the power system of the loader, a testing platform for the performance of the loader is developed, which is equipped with testing sensors and self-developed measuring devices. The parameters such as force of pin, pressure and flow of hydraulic system, displacement of cylinder, etc. During the shoveling operation of the loader are collected in real time by the sensors arranged on the platform and the relevant testing methods to calculate the performance parameters of the loader shoveling operation, and through automatic scooping and material preparation to ensure the repeatability of the test. Finally, relevant data is obtained through experiments, and the successful development of the loader shovel performance test platform is proved.
