Modeling and Simulation of the Dynamic Characteristics of a Hydraulic Power Limiting Valve with Two-Spring

Abstract:

A hydraulic power limiting valve, HPLV, is a key hydraulic element to realize power limiting control for hydraulic drive system in engineering machinery. By tracing with the discharge pressure of hydraulic pump, HPLVs are used to real-time control the pilot pressure that corresponds to the displacement of hydraulic pump, and match the output power of hydraulic pump with the power of its prime mover within high efficiency scope. So good dynamics is important for HPLVs to reflect the frequently change of pump pressure. Based on the description of a typical HPLV with two-spring structure, its principle and the working process are discussed, then the mathematical model is established and the effects of several main structural parameters on its dynamic characteristics are carried out.
