Due to its special design, the cavity inside the hinge can also be filled with an elastomeric filler material to provide vibration damping.
They are created by specially forming notches in the material, causing a much lower flexural strength at that point.
Space is introduced to the inner of the hinges which can be filled with elastomeric material to improve the damping coefficient.
Design parameterization Two materials are used for the hinge including aluminum alloy and silicone rubber.

Keywords: recycled aggregate concrete; workability; compressive strength; durability
Abstract: The properties of recycled coarse aggregate and the slump, the physical and mechanical properties and durability of recycled aggregate concrete were studied through tests.
Only small parts are used for buildings and roads cushion, but the vast majority else without any treatment are piled up, backfilled or used as road base material as low-level use of disposal [2].
Experiment 2.1 Materials Cement: P·O 42.5 from Luquan Dong Fang Zenith Cement Co., Ltd.
Under normal circumstances, the penetration of chloride ion is a combination of a number of ways, in addition to effects of chemical combination, physical bonding and adsorption between chloride ion and concrete materials [4].

This analytical model gives detailed geometrical parameters of the machine, where the maximum geometry, the working point of the magnet and the maximum flux density in the ferromagnetic materials were pre defined.
The main difference between the build-up of the two machines is the material of the piston rod.
ARMCO material were used, which has approximately 2 T saturation point.

Jiangxi science & technology normal university China
Key words: environmental art design, development reality, creative thinking, national concept, teaching reform
Abstract: Art design creative talent training can’t be separated from the teaching reform in colleges and universities, and the mission of art design creative talent training will be accomplished by the system of creative curriculum of the speciality eventually.
The construction of creative thinking training Creativity is the creation of the combination of science and technology and art.
Composition subjects are not only separate specialized courses, it is also a diversified science integrated ideas, social interpersonal relationships, environment, psychology, vision and science.
Art works is actually a kind of imagery activity, a kind of representation activity of emotion form, emotion symbols and emotion to constitute art works by materializing image with the aid of certain perceptual material medium .
