The invention relates to a piston shaker cooling simulation testing device and a test method thereof. The testing device includes a shaker cooling test stand, a simulation piston model, an oil supply system and high-speed photographic equipment. The shaker cooling test stand is provided with a high-speed reciprocating movement mechanism and a lead rail; the simulation piston model is formed by transparent material or a cooling cavity thereof is provided with a transparent window, and the simulation piston model is fixed on the high-speed reciprocating movement mechanism; an oil outlet of the oil supply system is communicated with the simulation piston model through an oil pipe; and the high-speed photographic equipment includes a camera, a timing control switch for continuously controlling the shoot of the camera at regular time and a memory. The camera constantly shoots the situation of coolant oil in the cooling cavity in the simulation movement of the simulation piston model. The testing device and the test method are strong in simulation degree, can record the condition of the coolant oil in a cooling channel of the piston model, the flow rate, flow velocity and distribution of the coolant oil in the cooling cavity and the oil injection performance of a cooling nozzle in real time, and then provide a foundation for analyzing the movement condition and fullness degree of the coolant oil and evaluating a piston product.
Description
technical field [0001] The invention relates to a piston oscillation cooling simulation test device for diesel engines and gasoline engines and a test method thereof. Background technique [0002] In order to prevent the pistons of diesel engines and gasoline engines from being overheated during violent oscillations and causing damage to the diesel engines and gasoline engines, the pistons of diesel engines and gasoline engines are generally provided with a cooling chamber, which has a cooling oil return channel, and the cooling oil passes through Cooling nozzle sprays into the cooling cavity of the piston phantom. [0003] At present, the domestic research on piston cooling mainly focuses on the temperature field test of the piston, but there is little research on the movement of the cooling oil inside the piston cooling chamber, which hinders further research and improvement on piston cooling. Contents of the invention [0004] The present invention provides a piston os...
