Abstract:As the core of the integrated hydraulic system,the design of the hydraulic manifold block is a complex and error prone job,especially selecting hydraulic components and their accessory parts,as well as the connection of the oil circuit.Using a simple and fast design method can greatly enhance the service rate for the design of hydraulic manifold block.A method of using SQL Server2008 database as the data source,net as development tool,and using the virtual pattern of hydraulic components was proposed,by which hydraulic components could be added quickly.So the design efficiency is improved,the design process of hydraulic integrated block is simplified.
