| Abstract: | Driving torque-driving speed-efficiency curve and key points of hydraulic-driving system has been deduced out by calculating and analyzing the power of driving and trenching system of chain trencher. According to the requirements of trencher, the electrical control scheme of driving is planned. The power allocation principle of engine and hydraulic-driving is discussed. Based on the power formula for trenching system, analyze factors of trenching power. The power allocation principle of driving and trenching is discussed further in combination with the power and torque characteristic curve of engine. The block diagram of control of chain trencher is also obtained. It can provide some theory references to power-matching and designing for chain trencher. |
