Abstract
The invention discloses a side force loading apparatus for a hydro-pneumatic spring testing bench. The apparatus comprises an installation end and a side force loading portion which are integrally arranged, wherein the installation end is used for connection with a side force actuator, and the side force loading portion is used for applying a pulling force or a pushing force to a hydro-pneumatic spring or simultaneously applying side forces in a bidirectional way. By use of the apparatus provided by the invention, various tests of hydro-pneumatic springs with different models under the effect of the side force can be satisfied, load conditions of the hydro-pneumatic springs during application can be simulated more really, and a hardware platform for science test verification is provided for research on the hydro-pneumatic springs.
Description
Technical field
The invention belongs to hydro-pneumatic spring testing equipment technical field, be specifically related to a kind of side force charger for hydro-pneumatic spring testing table.
Background technology
Hydro-pneumatic spring is generally be connected with car by hinge on vehicle, when the vehicle runs at a high speed or exercise bad environments when causing dust silt etc. to pollute hinge, there will be the situations such as hinge is stuck, this can cause hydro-pneumatic spring piston and cylinder barrel sidewall disalignment, hydro-pneumatic spring is made to be subject to side force, because manufacturing tolerance also can cause the right alignment between hydro-pneumatic spring piston and cylinder barrel not to be fine, this also can cause hydro-pneumatic spring at work by side force.If therefore think real simulated oil air spring load condition in working order, the existence of side force must be considered, need, while applying axial load to hydro-pneumatic spring, also to apply side load.
Summary of the invention
(1) goal of the invention
The object of the invention is: a kind of side force charger for hydro-pneumatic spring testing table is provided, realize applying dissimilar side force to different model, the tested hydro-pneumatic spring of structure, thus the stressing conditions of more real simulated oil air spring.
