Development of information technology makes the application of computer technology

in the machinery industry is rapidly increasing, it also enables engineers to hydraulic swivel fittings

develop products from the traditional manual drafting to CAD modeling direction, to

the era of electronic prototyping technology. CATIA parts design, assembly design,

DMU module, engineers can create 3D parts library, movement and assembly of products

as early analysis of the product, thus speeding up the progress of the design of the

assembly, improve design quality.hydraulic hose clamps

The virtual assembly of mechanical graduation project is an important part of

digital product definition. In this paper, based on process control as the center of

the virtual assembly design. Assembly design module constraints defined by the

designer, such as parallel, coaxial, angle or coplanar, etc., can control the

relationship between the geometric model, one of the comp onents is called to insert

the components, it can be in between the nodes modify the geometric parameters.

Virtual assembly according to the shape of the characteristics of the product

design, the progress of the characteristics of a true analog products, three-

dimensional assembly process, and allows the user to interactively control a 3D

realistic simulation of product assembly process can be assembled to test the

product.

Namely DMU Kinematics in CATIA prototype motion simulation, electronic prototype

motion mechanism simulation by simulating the mechanical movement to check agency

performance and movement analysis, a large number of kinematic constraints provided

by the calling system connection or through the automatic conversion of assembly hydraulic adapter fittings

constraints arising from a sports connection. then motion simulation of the

electronic prototype.

Mechanical graduation design and simulation is the application of computer a complex

system of reality through abstraction and simplification of a system model, this

model is then run on the basis of the analysis, thus the statistical properties of

the system. As the simulation is based on system model for the research methods of

the object without disturbing the actual production system, the simulation can take

advantage of fast computing power of the computer to obtain the parameters of the

actual production of a very short time simulation takes a long production cycle, so

, it can serve to shorten the decision time, to avoid the role of financial, human

and time wasted. The computer can also repeat the simulation, and optimization of

the implement ation of the program.

The simulation of the basic steps: Research Systems → → establish the simulation

model → run the simulation model → output and analysis system model.

Mechanical graduate design hydraulic manifold block is a key component in the

hydraulic system. Hydraulic manifold block is generally hexahedral structure of the

space above the installation of various hydraulic components (hydraulic valves,

fittings, accessories, etc.), while connected to its internal pore components pore

through, posing a loop system control requirements. Generally based on the basic

circuit of a typical hydraulic system, made of 6 faces of the general body manifold

(manifold block), usually four weeks in addition to a surface installation of the

hydraulic actuator fittings, and the remaining three surface installation standard

plate hydrau lic valves by manifold internal through-hole, oil contact between these

hydraulic valves, block upper and lower sides of the block between the superposition

of the joint surface, the cloth from the bottom up through the channel body, public

pressure hole, back hole, vent connection between the bolt holes in the hole and

block more than one loop laminated together, fastened together by four bolts, oil

contact between the oil block public hole.

The hydraulic manifold block intelligent design of modern hydraulic systems widely

used in integrated hydraulic valve configuration, because of their compact

structure, easy installation, small vibration, conducive to the realization of a

typical hydraulic system integration and standardization. The key parts - hydraulic

manifold block, has a dense and complex spatial channel system, the design work is

extre mely cumbersome, complex and error-prone.
