[Abstract]:This thesis is supported by the National Natural Science Foundation of China "Research on Harmonic Gear Drive and its Control Strategy of Giant Magnetostrictive Drive" (Project Grant No.: 51275069). Combined with harmonic gear transmission characteristics and magnetostrictive properties of Giant Magnetostrictive material. The harmonic gear drive device driven by giant magnetostriction is studied. First of all, starting from GMM's piezomagnetic equation, displacement-force output characteristics. The magnetostrictive characteristics and the output displacement-force characteristics of GMM are described. For the GMM rod with 蠁 4mm 脳 45mm in size, the structure size limit of the generator is combined with 160-type harmonic motor wave generator. The corresponding giant magnetostrictive actuator is designed. According to the design requirements of magnetostrictive microdisplacement amplification, a closed hydraulic microdisplacement amplifier with built-in temperature compensation mechanism is designed. Secondly, the electromagnetic field and temperature field of the designed giant magnetostrictive actuator are analyzed. According to the results of electromagnetic field numerical analysis, the magnetic field uniformity and magnetostrictive displacement are analyzed and calculated accordingly. Based on the results obtained from the numerical analysis of the temperature field, the temperature control model using phase change material (MG37) as an endothermic medium is evaluated. The corresponding Giant Magnetostrictive Actuator (GMA) was developed and calibrated by disc spring. The temperature characteristics of GMA and the effect of load on the output displacement of the actuator were studied experimentally. The displacement-force output characteristics, output displacement and force level of the GMM rod with size 蠁 14mm 脳 45mm are obtained. It provides a reference for the final determination of the GMM rod size specification for the 160 type giant magnetostrictive driven harmonic motor. Finally, the structure of 160 type giant magnetostrictive drive harmonic motor is designed. The structure is simple, the engineering application is easy, and it has good heat dissipation effect. It can effectively solve the problem of temperature rise of the whole machine and discuss the corresponding drive control strategy of the harmonic gear drive driven by giant magnetostriction. The research results lay a key technical support for the practical application of the harmonic gear drive driven by giant magnetostriction.
