Device and test method for simulating oil distribution of gearbox

The invention provides a test device and a test method for simulating oil distribution of a gear box, the test device comprises a target test object, a controller and a data processing assembly, the target test object comprises a tested gear box body, an oil inlet ring simulation assembly and a lubricating oil supply assembly, the oil inlet ring simulation assembly is arranged in the box body of the tested gear box, and the lubricating oil supply assembly is connected with the controller. The simulation assembly is used for simulating the lubrication state of the dynamic and static joint surface position of the gearbox and the planet carrier, and the data processing assembly is used for collecting, analyzing and integrating the temperature, pressure and total flow of lubricating oil of a target test object, the weight of the lubricating oil at each measuring point and the volume of the lubricating oil at each measuring point, and transmitting the collected data to the controller; the mass flow rate, the volum
