Main Factors

The interface of two low-density materials is bent in the forming process, which decreases the performance of materials. The theoretical analysis of the interface state in the forming process was taken to solve this problem, and the results indicated that the viscosity of the low-density material was very important to the interface state. The finite element simulation was also used to investigate the factors that affect the interface state. The results revealed the viscosity of material and the pressure were the main factors that affected the interface state; the stress and displacement at the interface could be accurately predicted by the finite element models. The ultimate aim was to modify the relevant parameters in a way that could obtain the required interface states.

The Impact

Giant magnetostrictive actuator is ideal for fast precision Alignment, but the nonlinear strain caused by temperature rise has serious impact on the control precision. This paper verifies the impact of strain caused by temperature rising on the experimental method, based on analyzing the principle of the giant magnetostrictive actuator. The copper consumption in giant magnetostrictive actuator coil , the iron consumption in the magnetostrictive rod and the corresponding method of inhibiting temperature rise were analyzed by theoretical analysis and finite element simulation.
