| Abstract: | One of the main vibration sources of large electromagnetic equipment is the magnetostrictive effect of the ferromagnetic materials inside.However,few studies take the magnetostriction effect after the saturation of ferromagnetic materials into consideration,not even the effects of different temperatures produced by equipment on the magnetostriction of ferromagnetic materials.This study presents a silicon steel sheet magnetostrictive measurement system suitable for general laboratory environments.What has been firstly designed is the solenoid which can produce applied magnetic field to stimulate the deformation of silicon steel sheet and using High-temperature co-fired ceramics(HTCC)and temperature sensor to regulate and control the temperature of silicon steel sheet.Then,the determination of silicon steel sheet deformation is based on a high precision strain resistance sheet.Finally,through theoretical simulation and experimental research,this equip can measure the magnetostrictive rate accurately in saturation condition and in different temperatures and provide reliable evidence for the design,production and vibration monitoring of electromagnetic equipment. |
