Scope

Main technical content: The operation requirements of the oil-gas suspension system also include an oil circuit control valve block, which is arranged on the pipeline and controls the connection between the oil-gas suspension cylinders and the connection between the accumulator and the oil-gas suspension cylinders. The oil circuit control valve can control the connection between the oil-gas suspension cylinders and the connection between the accumulator and the suspension cylinders, enabling vertical stiffness testing of single-cylinder and connected oil-gas suspension systems. In addition, the oil circuit control valve block can also connect the oil-gas suspension cylinders on different oil-gas suspension cylinder groups with each other to form different connection modes, thereby achieving the rollover performance of the oil-gas suspension system under various connection modes. The pressure sensor should meet the requirements of JB/T 6170-2006 and the performance test requirements of GB/T 15478-2015. The pressure sensor is connected to the inlet and outlet ports of the oil-gas suspension cylinders, and is used to test the oil pressure changes in the rod chamber and the rodless chamber of the oil-gas suspension cylinders. The hydraulic servo control system includes an industrial computer, a hydraulic pump, a servo valve, and a servo amplifier. The industrial computer sends a signal to the servo valve through the servo amplifier, and the hydraulic pump should meet the requirements of GB/T 7935-2005 while providing pressure oil. The servo valve controls the opening degree of the oil circuit according to the signal, thereby controlling the movement of the actuating hydraulic cylinder. The test method of hydraulic servo control should meet the requirements of GB/T 32216-2015. The hydraulic servo control system also includes a displacement sensor, which is installed on the base and parallel to the oil-gas suspension cylinders, and is used to test the displacement deforma
