A Frequency Modulation GMI Magnetic Sensor base on Inverter Multivibrator with Longitudinal Excitation Bo Yang1, a, Xiongzhu Bu 1,b and Xianjin Huang1,c 1 School of Mechanical Engineering, Nanjing University of Science and Technology , Nanjing, 210094, China ayangbo0286@163.com, bbuxu105@njust.edu.cn, c kwuai@sina.com Keywords: giant magnetic impedance effect; amorphous ribbons; weak magnetic sensor; frequency-modulation ; Abstract.
Compared with the circumferential driving mode, the excitation current of the longitudinal driving mode does not directly contact the amorphous ribbon, which could simplify the manufacturing process of the sensing head and promote temperature stability by avoiding the material’s own Joule heat loss.

The measurements of mechanical properties of constructional materials are taken during tensile, compression or torsion tests of material specimens.
It’s necessary to mention that authors didn't find in the accessible literature static and dynamic properties of similar structural materials tested here used in the military armament technology.

The results showed that the loose state was related to vibration frequency, fitting clearance, friction coefficient, element materials.
Not only the bolt material will affect the anti-loosening characteristic, and the fitting part materials, such as nut or gasket, will also affect the fasteners’ anti-loosening characteristic.
The reason is the surface roughness and mechanical properties of the materials are different.

Introduction The synthesis of polymeric materials, using renewable resources, has been subject of research in the last decades.
Polyurethanes are becoming increasingly important as engineering materials because they have excellent abrasion resistance and the properties of both elastomers and plastics.
Although, polyurethane are very versatile polymeric materials and widely used in foam, elastomers, plastics, adhesives, coating, leather-like materials and finishes but they show poor thermal resistance and barrier properties, which limit their applications.
