Method of Measuring Deformations of Magnetoactive Elastomers under the Action of Magnetic Fields

摘要: Magnetic deformation is a change in the size and shape of sample under action of a uniform external magnetic field. The study this effect various materials provides deep understanding nature mechanical interactions. Moreover, magnetic deformation great interest from an engineering point view for designing new devices. In magnetoactive elastomers containing microparticles polymer matrix, giant deformation detected generally accepted methods measuring soft are now practically absent. article describes installation magnetomechanical characteristics of demonstrates its experimental capabilities. installation allows to measure deformations range 0 12.5 mm with resolution 1 micron. The curves obtained using these installations required developing actuators and sensors based on elastomers, also improving their manufacturing technologies.
