Abstract
Disclosed is a novel hydraulic transmission test bed. Based on a hydraulic system of a present test bed, two travel switches, an electric-hydraulic proportional overflow valve, an electric-hydraulic proportional velocity regulating valve, a flow sensor, a temperature sensor and a pressure sensor are added. The above travel switches, the temperature sensor, the flow sensor, the pressure sensor, the electric-hydraulic proportional overflow valve and the electric-hydraulic proportional velocity regulating valve are all connected with a PCI multifunctional interface card in a computer. The novel hydraulic transmission test bed operates stably, has accurate experimental data and is adopted to raise efficiency of experiments. In the meantime, the interest of students in experiments is greatly raised by an integrative technique of mechanics-electronics-hydraulics, and the experiment effect of the novel hydraulic transmission test bed is obviously superior to that of previous pure hydraulic technology experiments.
