Additional studies, however, are insufficient. In particular, automated driving vehicles do not need human driving, so unlike conventional vehicles, the drivers obtain the freedom to do other activities inside the vehicle. The aim of this paper is to collect previous research data and to predict and analyze various activities expected from the passengers of automated driving vehicles. Also, this paper investigates and analyzes the functions and arrangements of passenger plane and ship seats, as well as the current vehicle seats. Then, it proposes the functions and features of seats required by automated driving vehicles. In addition, it checks the validity of the predictions by comparing them with automated driving concept vehicles submitted to motor shows and CES by the global automakers, the Tier1, and 2 automotive suppliers. Patents for applications, registrations, and prospective registrations were investigated to identify trends in automated driving vehicle seat technology. It also draws out what is different from the current vehicle seats in automated driving vehicle seats. It was intended to suggest the direction to move forward in the research and development of seats for automated driving vehicles. And this paper not only proposed the function and features of seats of automated driving vehicles that have not yet been commercialized, but also considered possible problems during commercialization and suggested solutions to them. The upcoming automated driving vehicle regulation trends have been investigated to confirm the validity of this paper. Based on this, additional studies needed for commercialization of automated driving vehicles were considered.์ž์œจ์ฃผํ–‰์ฐจ์˜ ์ƒ์šฉํ™”๋ฅผ ์œ„ํ•ด์„œ ์ง์ ‘์ ์œผ๋กœ ์—ฐ๊ด€๋œ ๊ธฐ์ˆ ๊ณผ ๊ด€๋ จ ๋ฒ•๊ทœ ์ œ์ •์— ๊ด€ํ•œ ์—ฐ๊ตฌ๋Š” ๋งŽ์ด ์ง„ํ–‰๋˜๊ณ  ์žˆ๋‹ค. ํ•˜์ง€๋งŒ ๊ทธ ์™ธ์— ๋ถ€์ˆ˜์ ์ธ ์—ฐ๊ตฌ๋“ค์€ ๋ฏธํกํ•œ ์‹ค์ •์ด๋‹ค. ํŠนํžˆ ์ž์œจ์ฃผํ–‰์ฐจ๋Š” ์ธ๊ฐ„์ด ์ง์ ‘ ์šด์ „์„ ํ•  ํ•„์š”๊ฐ€ ์—†๊ธฐ ๋•Œ๋ฌธ์— ๊ธฐ์กด์˜ ์ฐจ์™€๋Š” ๋‹ค๋ฅด๊ฒŒ ์‹ค๋‚ด์—์„œ ๋‹ค์–‘ํ•œ ํ™œ๋™๋“ค์„ ํ•  ๊ฒƒ์œผ๋กœ ์˜ˆ์ƒํ•˜๊ณ  ์žˆ๋‹ค. ๋”ฐ๋ผ์„œ ๊ธฐ์กด ์—ฐ๊ตฌ์ž๋ฃŒ๋“ค์„ ์ˆ˜์ง‘ํ•˜์—ฌ ์ž์œจ์ฃผํ–‰์ฐจ ์—์„œ ๊ธฐ๋Œ€๋˜๋Š” ์Šน๊ฐ๋“ค์˜ ๋‹ค์–‘ํ•œ ํ™œ๋™๋“ค์— ๋Œ€ํ•˜์—ฌ ์˜ˆ์ธกํ•˜์—ฌ ๋ณด๊ณ , ํ˜„์žฌ ์ฐจ๋Ÿ‰์šฉ ์‹œํŠธ๋งŒ์ด ์•„๋‹ˆ๋ผ ์—ฌ๊ฐ๊ธฐ์™€ ์—ฌ๊ฐ์„ ์˜ ์‹œํŠธ๋“ค์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์กฐ์‚ฌํ•˜๊ณ  ๋ถ„์„ํ•˜์—ฌ, ์ž์œจ์ฃผํ–‰์ฐจ์—์„œ ํ•„์š”ํ•œ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์ œ์•ˆํ•˜๊ณ ์ž ํ•œ๋‹ค. ๋˜ํ•œ ํ˜„์žฌ๊นŒ์ง€ ๋ชจํ„ฐ์‡ผ์™€ CES์— ์ถœํ’ˆ๋œ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ๋ถ„์„ํ•˜์—ฌ ๋…ผ๋ฌธ์—์„œ ์ œ์•ˆํ•œ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜์˜ ํƒ€๋‹น์„ฑ์„ ํ™•์ธํ•˜์—ฌ ๋ณด์•˜๊ณ , ํ˜„์žฌ๊นŒ์ง€ ์ถœ์› ๋ฐ ๋“ฑ๋ก๋œ ์ž์œจ์ฃผํ–‰์ฐจ ์‹œํŠธ ๊ด€๋ จ ํŠนํ—ˆ ์กฐ์‚ฌ๋ฅผ ํ†ตํ•˜์—ฌ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์—์„œ ๊ธฐ์กด ์ฐจ๋Ÿ‰์˜ ์‹œํŠธ์™€๋Š” ๋‹ค๋ฅด๊ฒŒ ์ค‘์ ์„ ๋‘๊ณ  ์žˆ๋Š” ๋ถ€๋ถ„์ด ๋ฌด์—‡์ธ์ง€๋ฅผ ํ™•์ธํ•ด๋ณด๊ณ  ์•ž์œผ๋กœ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ ์—ฐ๊ตฌ ๋ฐ ๊ฐœ๋ฐœ์—์„œ ๋‚˜์•„๊ฐ€์•ผํ•  ๋ฐฉํ–ฅ์„ ์ œ์‹œํ•˜๊ณ ์ž ํ•˜์˜€๋‹ค. ๊ทธ๋ฆฌ๊ณ  ๋ณธ ์—ฐ๊ตฌ๋Š” ์•„์ง ์ƒ์šฉํ™” ๋˜์ง€ ์•Š์€ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์ œ์•ˆ์œผ๋กœ๋งŒ ๊ทธ์น˜์ง€์•Š๊ณ  ์ƒ์šฉํ™” ์‹œ์— ๋ฐœ์ƒํ•  ์ˆ˜ ์žˆ๋Š” ๋ฌธ์ œ์ ์— ๋Œ€ํ•ด์„œ๋„ ๊ณ ๋ฏผํ•˜๊ณ  ๊ทธ์— ๋Œ€ํ•œ ํ•ด๊ฒฐ๋ฐฉ์•ˆ์„ ์ œ์‹œํ•˜์˜€๋‹ค. ๋งˆ์ง€๋ง‰์œผ๋กœ ๋‹ค๊ฐ€์˜ค๋Š” ์ž์œจ์ฃผํ–‰์ฐจ์— ๋Œ€์‘ํ•œ ์ „์„ธ๊ณ„์˜ ์ฐจ๋Ÿ‰ ๋ฒ•๊ทœ ํŠธ๋žœ๋“œ๋ฅผ ์กฐ์‚ฌํ•˜์—ฌ ํ˜„์žฌ ์ฐจ๋Ÿ‰ ๋ฒ•๊ทœ์˜ ํ‹€์—์„œ๋Š” ๋ฒ—์–ด๋‚œ ๋ณธ ์—ฐ๊ตฌ์˜ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹ค๋‚ดํ™˜๊ฒฝ ๋ฐ ์‹œํŠธ๋ฅผ ์—ฐ๊ตฌ์˜ ํƒ€๋‹น์„ฑ์„ ํ™•์ธํ•˜์˜€์œผ๋ฉฐ, ์ด ํƒ€๋‹น์„ฑ์„ ๊ทผ๊ฑฐ๋กœ ์ž์œจ์ฃผํ–‰์ฐจ ์ƒ์šฉํ™”๋ฅผ ์œ„ํ•˜์—ฌ ํ–ฅํ›„ ํ•„์š”ํ•œ ์ถ”๊ฐ€ ์—ฐ๊ตฌ๋“ค์— ๋Œ€ํ•˜์—ฌ ๊ณ ๋ฏผํ•˜์—ฌ ๋ณด์•˜๋‹ค.Abstract i Contents iii List of Tables v List of Fugures vii 1.

The proton injector in the study transports a high-current and low-energy proton beam with minimum loss and makes the beam parameters matched to a subsequent accelerator such as radio-frequency quadrupole. A high-current proton beam contains strong space charge effect and non-linear electric field, increasing beam size and emittance during transport. To reduce the beam size, solenoid focusing lens is used, which rather causes spherical aberration and another emittance growth. In addition, the presence of such an electromagnetic element gives rise to alignment error. Solenoid magnet makes it difficult to control a position of beam centroid since it has characteristics of rotating and coupling the beam in the transverse plane. This study has established a proton injector test stand and introduced novel techniques to improve the low energy beam transport in a high-intensity proton injector. Proton injector test stand includes transverse beam profile monitor, which is composed of a scintillation screen and a CCD camera, to measure the position, size, and emittance of the beam. Two key factors for improving low-energy beam transport are low beam emittance and a fast and accurate beam tuning method. For this purpose, a residual gas molecule analysis method and an artificial neural network (ANN) model are introduced. As a first result, low beam emittance was measured by preventing beam emittance from growing through an inert gas injection technique based on numerical analysis on steady-state pressure in high vacuum condition. A space charge potential increases beam emittance, not preserving the intrinsic emittance at the beam extraction region. One of the natural processes to cancel space charge force is that proton beam collides with residual gases mainly composed of hydrogen molecules flowing out of ion source and air molecules, causing some ionization. It is a self-neutralization that the generated electrons are trapped in the space charge potential of the beam. It is known to be more effective as the number of residual gas molecules in the transport pipe increases and the heavier inert gas molecules are involved since they generally have larger collisional cross-section. Suppression of emittance growth is achieved and beam emittance is decreased up to 23% through the residual gas injection. Artificial neural network (ANN) model can greatly reduce time and increase accuracy in low energy beam tuning. There are unknowns such as alignment errors that are difficult to measure between elements involved in the beam transport process, such as beam extraction, focusing, and deflection. To correct for these errors, steering magnets control the beam centroid in the transverse plane. In order to optimize the beam transport, it is necessary to observe the change of beam centroid and size for various magnet settings. Multi-layer perceptron model is utilized to interpret this nonlinear relationship and to control the beam properly based on the measured data. Extensive beam dynamics simulations are performed to verify the efficient training and the practicality of the predictive model. The output results of calculating the beam size and beam position at a specific location are obtained according to various sources of errors and unknowns that may occur in the LEBT. It is confirmed that the predictive model with high accuracy can be derived from sufficient measurement data, and it is applied to actual beam diagnosis and beam control experiments. The ANN model developed in this study shows more accurate prediction at a speed 49 times faster than the existing scan method. This study contributed to the suppression of the beam emittance growth and the development of a fast and accurate beam transport control technique in high intensity proton injector. This can be applied to the evaluation and improvement of beam emittance in beamlines under various conditions by increasing the utility of beam diagnostic data. In addition, there is a possibility to greatly improve beam tuning efficiency to higher energy sections and beamlines that have more control variables and are more complex than low-energy beam transport systems. Ultimately, the study can be developed as a base technology for autonomous operation of accelerator with minimum human intervention.๊ณ ์ถœ๋ ฅ ์–‘์„ฑ์ž ๊ฐ€์†๊ธฐ๋Š” ์ž˜ ์ •๋ฆฝ๋œ ๊ธฐ์ˆ ๊ณผ ์—ฐ์†

To describe the thermal effects of cryogenic fluids and two-phase flows, we used the additional governing equation for one-phase mass conservation law and accurate equation of states. Also we used the stable and accurate numerical schemes for cavitating flows which incompressible and compressible regimes are co-exists. As a results, we simulated cavitating flows around turbopump inducer with cold water and cryogenic fluids, and examined the differences of flow characteristics depending on the working fluids.๋ณธ ์—ฐ๊ตฌ๋Š” ๊ต์œก๊ณผํ•™๊ธฐ์ˆ ๋ถ€์˜ ์šฐ์ฃผ๊ธฐ์ดˆ์›์ฒœ๊ธฐ์ˆ ๊ฐœ๋ฐœ ์‚ฌ์—…(NSL,National Space Lab, No.20120009099)์˜ ์ง€์›์„ ๋ฐ›์•„ ์ด๋ฃจ์–ด์กŒ์Œ.OAIID:oai:osos.snu.ac.kr:snu2013-01/104/0000004648/7SEQ:7PERF_CD:SNU2013-01EVAL_ITEM_CD:104USER_ID:0000004648ADJUST_YN:NEMP_ID:A001138DEPT_CD:446CITE_RATE:0FILENAME:FA1-2.pdfDEPT_NM:๊ธฐ๊ณ„ํ•ญ๊ณต๊ณตํ•™๋ถ€EMAIL:[email protected]:
