Background
The oil-gas buffer mainly comprises an outer cylinder and a piston rod, wherein the outer cylinder and the piston rod form an oil cavity and a gas cavity, the oil cavity is filled with damping oil, and the gas cavity is filled with dry air or inert gas. When the buffer works, external force pushes oil in the oil cavity to flow into the air cavity through the piston rod, and the oil flows through the small holes to generate damping to dissipate impact energy of the buffer under the action of the external force; the pressure generated by the gas compression of the gas chamber forces the oil to flow back to the oil return cavity through the small hole, so that the gas and the oil can absorb energy simultaneously. The oil-gas buffer has good buffering and damping effects, is widely applied to the industries of automobiles, aerospace, metallurgy and manufacturing, and has larger difference between the actual performance and the theoretical performance because the finished oil-gas buffer can not give an accurate performance map. In order to improve the accuracy of the model selection of the product oil-gas buffer and evaluate the performance of the self-polishing oil-gas buffer, an oil-gas buffer performance detection device is needed.
