Description
technical field [0001] The present application relates to the technical field of pressure compensation valves, in particular to a parameter sensitivity analysis method of a pressure compensation system after a valve. Background technique [0002] As the core component of the load-sensitive proportional multi-way valve, the pressure compensation valve ensures that the flow required for the action of each actuator is distributed in proportion, so that the movement speed of each actuator is not affected by the load, and the function of the entire valve and even the entire system work performance plays a decisive role. The sensitivity analysis method is used to explore the key parameters affecting the dynamic characteristics of the load-sensitive proportional multi-way valve in the pressure compensation valve, which lays a research foundation and theoretical basis for optimizing the dynamic characteristics of the load-sensitive proportional multi-way valve and the design paramet...
