Lightweight design of 45000r/min spindle using full factorial design and extreme vertices design methods

引用

Journal of Central South University 2011年第1期18卷 153-158页

作者： park seong-jin LEE Choon-man HWANG Young-kug Department of Mechanical Design and Manufacturing Engineering Changwon National University

Factors for determining the spindle size are the shaft diameter, positions of bearing and motor, and entire length of the spindle. Then, it is important to find the assembling of the optimal design variables, which satisfy the stiffimss and rotational speed required to the spindle. A general full factorial design method was used to verify some factors that affect the natural frequency of a spindle. It is verified that the shorter shaft length and bearing span length represent the higher natural frequency, and there are some effects according to the change in the levels of factors. The detailed spindle dimension is determined by applying an EVD method, which can define the optimal bearing position through considering the limiting condition. Based on the estimated regression model, the optimal spindle size and bearing distance that can improve the primary natural frequency are obtained, and the influence of design factors on the natural frequency is also analyzed.

Assembly of charged aerosols on non-conducting substrates via ion-assisted aerosol lithography （IAAL）

引用

Particuology 2017年第4期15卷 17-23页

作者： Seunghyon Kang Wooik Jung Dae seong Kim Sei jin park Mansoo Choi School of Mechanical and Aerospace Engineering Seoul National University Seou 108826 Republic of Korea Global Frontier Center for Multiscale Energy Systems Seoul National University Seou108826 Republic of Korea

The development of ion-assisted aerosol lithography （IAAL） has enabled fabrication of complex three- dimensional nanoparticle （NP） structures on conducting substrates. In this work, the applicability of the IAAL technique was investigated on non-conducting substrates. The NP structure growth process on a non-conducting substrate was found to self-terminate and the structures subsequently repel incoming charged NPs and scatter them away. Electric field calculations supported the experimental findings and confirmed that the electric field distortions owing to charge build-up within the structures prevented additional NP deposition thereon. To regulate the charge build-up without compromising the number of NPs available for assembly, a corona discharger and an ion trap were implemented. By varying the number of ions available in the assembly process, an optimum level of ion injection was found that allowed for a prolonged （〉120 rain） assembly of NP structures on non-conducting substrates without the unwanted scattering of NPs.
