Substrate Effects of Magnetostrictive Thin Film on Magnetostriction for Automotive Parts Application
Magnetostrictive thin films can be applied in transmission system for the enhancement of energy efficiency. In this study, four kinds of substrates (Si, glass, Fe, polyimide) with the magnetostrictive thin film layers are prepared and investigated to characterize the magnetic and mechanical behaviors due to the substrates effects. The fabricated substrates have thicknesses of 50, 150 and 500um with cantilever shape. TbDyFe films are deposited by DC magnetron sputtering with 1～10m thick. The deposited film thicknesses are verified using X-ray diffraction. The magnetization of each sample is examined using VSM(Vibrating Sample Magnetometer) and magnetostriction is also measured using capacitance method to characterize magneto-mechanical behaviors. The magnetostriction results as deflections are compared and the results are discussed for micro actuator applications.

The shape of tire footprint is one of the important factor which affects to the performance of tire such as handling, ride and wear. In this study, the effect of the stiffness for tire footprint is investigated. Some tires on the market were selected and tested the vertical stiffness, lateral stiffness by stiffness measuring system. And the contact length, contact width and contact area are tested, too. The contact width and length is reduced by the increase of the tire stiffness. According to the change of the tire stiffness, the leading edge and trailing edge in the footprint have a different shape.

This paper is concerned with formulating the design specification and making hyperbaric oxygen chamber for multi-users. HBOT(Hyperbaric Oxygen Therapy) is very effective remedy for increasing the concentration of melted oxygen in human and animal body. The melted oxygen supplies to each cell in body to recover the normal condition. This research reported the design specifications and mechanical test results of hyperbaric oxygen chamber made with polyurethane as well as computational analysis with CATIA program. These data can set the physical dimensions of practical HBOT equipment for multi-users and be used to produce the effective commercial model.

In this study, mold core of can type lens for optical communication has been fabricated and heat transfer analysis has been conducted. Through this study, results were obtained as follows. Surface roughness of upper and lower cores by ultra precision grinding were Ra 0.002074(um) and 0.004316(um), respectively. Design P-V and Bestfit P-V as shape accuracy of upper core were 0.0858(um) and 0.0843(um), respectively, and those of lower core were 0.0957(um) and 0.0546(um), respectively. The temperatures of upper and lower surfaces of lens during machining obtained by heat transfer analysis were 576.05℃ and 576.4℃, respectively. In case of inner sleeve, it was estimated that the temperature of the side surface were 575.95℃ by heat transferred from lower core. The maximum and minimum temperatures of lower surface of lens were 576.4℃ and 575.96℃, respectively, according to the positions of holes for air circulation from out side.
