[Abstract]:Based on the principle of speed regulation of differential planetary gear, a hydraulic hybrid power cutting drive system of shearer with adjustable cutting speed is designed. According to the composition of the system, the mathematical model and control method of the key components are established. Based on AMESim software, the dynamic characteristics of hydraulic motor and drum and the buffer performance of hydraulic hybrid power system are analyzed. The results show that the hydraulic hybrid power cutting transmission system can adjust the cutting speed of the shearer, and it has better cutting performance than the traditional constant speed cutting shearer under the complex coal seam. The hydraulic motor and drum can track the target speed accurately, and the hydraulic system can mitigate the shock caused by the sudden load.
