Analysis of Machinery Manufacture and Production from the Metal Mechanics Perspective

ndustry is the foundation of national economy and military development, and machinery manufacture and production is the main content of industry. Therefore, each country attaches great importance to its own machinery manufacture capacity and production levels. Influenced by the special historical factors, China's economy started relatively late, with a low machinery manufacture capacity. To essentially change this phenomenon, the selection and processing technology of metal materials must be optimized. This paper analyzes the concept and characteristics of metal mechanics, together with the present situation of China's machinery manufacture and production. After studying the relationship between metal mechanical and machinery manufacture and production, it is found that the use of metal mechanics can improve the quality of mechanical products.

Analysis on Measurement Errors of Critical Dimensions of HSK Cone and its Application

The manufacture and assembly accuracy of the HSK taper inspection gauge directly influences the measurement precision. Take the large taper measuring head of the HSK-A63 taper inspection gauge as the research object, analyzed the measurement errors caused by its mounting position deviations, obtained corresponding formulas. Based on the structure of the inspection gauge and the moderate accuracy required by machinery manufacture and mechanical assembly, assigned value for each parameter, and the specific measurement errors were calculated. Guiding suggestions for the manufacture and assembly of the HSK taper inspection gauge were proposed.

Research on Engineering Machinery Manufacturing PDM and CAD Integration Solutions

In the construction machinery manufacture enterprises, the diversified users, individual needs and various products purchasing manners become the market mainstream. Based on the common problems existing in the informatization implementation of current construction machinery manufacture enterprise, this paper focuses on the product design characteristics and production management in construction machinery industry, relies on advanced design and manufacturing technology, modern management technology and information technology, combines with the results and experience of enterprise informatization, analyzes the bottleneck of enterprises and proposes the general plan the construction manufacture enterprise implement information through analyzing the information needs in construction machinery industry and actual situations, also proposes PDM and CAD integration programs according to the situations of PLM software functions and enterprise graphics software.

Simulation Analysis of the Pier of Urban Landscape Bridge

The landscape is very important for the overpasses and other bridges built in the city. Not only should it be integration with land, sky and surrounding scenery, but also reflects the city's humanities content and historical background. Structures with landscape features, of which the forces are different from the normal structures, often have rather special characteristics. To ensure the safety of these structures, the test is often needed, and of course a lot of test equipments, sites and costs etc are required.Without the need of test sites, testing instrument, and test model fabricating, the simulation analysis, which could get better effect than actual model test in some cases, has been extensively applied in lots of industries, such as machinery manufacture, aerospace, civil engineering, etc. Be great reference value for the design of the bridge, the simulation process and relevant conclusions of a curve pier in Hefei (the flower city in China) are described in this paper.
