Abstract

The shear stress-generating system is designed and calculated in low-frequency mechanical spectrum apparatus to obtain the 10-3 relative strain for the pure Al specimen with dimensions Ø1mm×50mm in this paper. The physical dimension of Helmholtz coil, the specification of enamel wire and the number of turns as well as the current flow of coil and the specification of power-amplifier source are designed according to the strain value. The acting force between the magnetic field caused by Helmholtz coil and the magnet steel is analyzed. It has been calculated that the diameter of copper enamel wire is 1.12mm, the number of turns is 1734, the inner and the external diameter of coil are 40 mm and 120mm respectively and the length is 60mm. If the load voltage of power-amplifier source is 30V and the currency is 4.48A, the uniform magnetic field of 0.07T is produced in the center region of Helmholtz coil and the force applied to the magnet steel will be beyond 26 N.
