Structure Optimization Design Of The Precise Flux Valve Driven By Piezoelectric Ceramics

In the research of domestic and international structure of the flow valve design and structure optimization, the majority of scholars around these three problems:cavitation and cavitation erosion drawing erosion and erosion, leakage and efficiency. Most of the scholars take the application of the design of new structures and new materials as an important method to solve the problem.The emergence of piezoelectric ceramic and metal rubber material and the two kinds of materials in an attempt to apply in many aspects brings to the structural design and manufacturing of hydraulic valve a new method and put forward new solution to hydraulic valve for about cavitation and other common problems.This paper mainly through ANSYS finite element technique and numerical simulation method investigate the optimization method of hydraulic flow valve.Firstly,after fully understanding the current research situation of the hydraulic valve, the main problem facing and development prospects, according to the principle of work and the actual work requirements, application of ANSYS finite element analysis of the static and dynamic characteristics resulting valve amplification mechanism static pressure and deformation cloud points out optimization direction;Secondly,the finite element modal and harmonic response analysis for the structure design of the later provides reliable theory, using APDL language to establish the model of amplification mechanism parameters by parameter optimization method is quick and convenient to complete the structure design;Finally, analyze the influence of hydraulic valve structure of the valve in fluid flow by the method of numerical simulation. repeated testing to the flow field simulation determine the final design process according to the occurrence of cavitation theory and hydraulic principle.
