| Abstract: | The giant magnetostrictive material performance of giant magnetostrictive actuator is obviously affected by heat,so the accuracy of positioning of GMA is affected also.In the work,a new simplified compulsory water cooling control strategy is proposed for GMM constant temperature.Based on this,the coupled turbulent flow field and temperature field finite element model is created for GMM smart component.The model is simulated by applying COMSOL Multiphysics 3.4.The temperature control strategy validity is proved by simulation and experiment.. |
