Hydro-pneumatic spring test bench with side force simulation device

Abstract

The invention discloses a hydro-pneumatic spring test bench with a side force simulation device, and the test bench comprises a fixed rack with a function of damping, a movable rack, an axial load simulation hydraulic actuator, a side force simulation actuator, a side force simulation actuator support, side force loading tools, a hydro-pneumatic spring, a controller, and a hydraulic system. The test bench can achieve the testing of all items when a side force is applied to a tested hydro-pneumatic spring, simulates the load condition of the hydro-pneumatic spring in use more truly, and provides a hardware platform of scientific experimental verification for the research of the hydro-pneumatic spring. Moreover, there are various types of side force loading tools, thereby meeting the requirements of the testing of all items of different types of hydro-pneumatic springs under the action of the side force.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and relates to an oil-gas spring test bench with a lateral force simulation device, which is mainly used for performing durability tests on oil-gas springs when lateral forces are applied, and friction under lateral force conditions. force test etc. Background technique [0002] Oil-gas springs are widely used because of their non-linear variable rigidity and gradual increase characteristics, which can well meet the requirements of vehicle driving stability and cushioning reliability. The test bench for oil-gas spring static and dynamic characteristics tests is also relatively Mature, but none of the existing oil-pneumatic spring test rigs are capable of lateral force loading. The oil and gas spring is generally connected to the vehicle by hinges. When the vehicle is running at high speed or the driving environment is poor and the hinge is polluted by dust and sand, the hinge will be stuc...

Problems solved by technology

[0002] Oil-gas springs are widely used because of their non-linear variable rigidity and gradual increase characteristics, which can well meet the requirements of vehicle driving stability and cushioning reliability. The test bench for oil-gas spring static and dynamic characteristics tests is also relatively Mature, but none of the existing oil-pneumatic spring test rigs are capable of lateral force loading

The oil and gas spring is generally connected to the vehicle by hinges. When the vehicle is running at high speed or the driving environment is poor and the hinge is polluted by dust and sand, the hinge will be stuck, which will cause the piston of the oil and gas spring to be inconsistent with the side wall of the cylinder. Coaxial, so that the oil-gas spring is subject to lateral force, due to machining errors, the coaxiality between the oil-gas spring piston and cylinder is not very good, which will also cause the oil-gas spring to be subjected to lateral force during work
