Study on Modeling Technique about Complex Valve Body Based on Reverse Engineering Qu Li-ganga , Qin Zheng-qi b School of Mechanical &Electrical Engineering, Shenyang Institute of Aeronautical Engineering, Liaoning, Shenyang, P.R.China, 110136, a qulg@syiae.edu.cn, bqinzhengqi1974@163.com Keywords: Reverse engineering; valve body with complex structure; internal cavity duplication; data processing, modeling Abstract.The reverse modeling solution and its key technologies about complex part with internal cavity are introduced in this paper, taken the casting valve body for an example.
Introduction Reverse Engineering(RE) is becoming one of the important modern manufacturing technologies combined with measuring and CAD techniques.
But there are many kinds of parts with complex internal cavity in practice, valve body for example shown as Fig.1, measuring the engineering data of internal cavity or surface is becoming the technical bottleneck in course of implementing reverse engineering[4].
It is not easy to measure the data of the internal cavity of valve body while the reverse engineering technology is employed to develop it.
The liquid silicon rubber, mixed with proper vulcanizator, is filled into the internal cavity of the valve body, taken out after solidification, and smoothening the surface of the entity to prepare for measuring and collecting engineering data, the silicon rubber entity is illustrated in Fig. 2.

The article sums up post--disaster reconstruction of underground engineering.
In the post-disaster reconstruction, underground engineering is the key point.
But the concrete construction is the key to underground engineering, concrete should have not only high performance construction and strength and durability, but also requires the maintenance of the ecological characteristics.
In order to reduce the dosage of cement and concrete, the development of green high performance concrete mixed up with industrial waste slags makes concrete which is the biggest artificial materials become truly sustainable material.
The green high performance concrete technology and engineering application.

The paper carries out a classification of the mega-accidents in electrical engineering, and conducts a three-dimensional analysis of the accident risk in electrical engineering.
Wu (2008) [7] analyzed several typical OPGW failures that had happened during installation and operation. 2 Sources and Relations of Risk in Electrical Engineering The risk of electrical engineering accidents can be summarized into three risk layers of the sources: Risk sources from organizational layer, material layer and individual layer.
Risk Sources of Electrical Engineering Accidents Relation Diagram 3 The Classification of Electrical Engineering Accidents Based on case study and the logic of Figure 1, here break down the risk sources of electrical engineering to layers.
While the risk sources of the resource are mainly raw materials, natural attributes, such as flammable and explosive hydrogen gas, dissolution of local water and etc.
Risk Sources Layers of Electrical Engineering Accidents.

Since the technology of engineering drawing come into being, two-dimensional engineering drawing has become the engineer’s common language and played the critical role.
A question arises obviously, why we need the 2D engineering drawings in the engineering field for so long time?
It plays an important role in engineering area especially in China.
They can obtain information about technical requirements, materials, imbedded parameters and so on.

Assessment of the unstressed lattice parameters for residual stresses determination by neutron diffraction in engineering materials M.
Knowledge of the spatial and directional distribution of internal residual stresses (RS) is increasingly considered fundamental to determine their influence on properties of engineering materials and a consequent material behaviour.
In this work, the state of the art is introduced and discussed, mainly related to engineering materials and industrial applications.
Some practices, however, allow obtaining d0 values acceptable for applications regarding engineering materials.
