This paper is about optimization design and analysis verification of automotive electronic actuators. An electronic actuator for a vehicle is composed of a motor, a reducer, and a controller for controlling the motor. In recent years, metal gears have been replaced by plastic gears. Plastic gears have advantages in cost, weight, noise reduction, etc., but the size increase and durability of steel gears are reduced. Therefore, it is necessary to optimize the design in order to minimize the disadvantages of the plastic gear, and to ensure structural safety. Structural analysis was performed on design parameters such as material, module, and thickness of plastic gears to select the optimal parameters, and plastic gears were optimized for design. In addition, a prototype was developed to compare the test results with the analysis results to ensure the correlation between the analysis models and to build an analysis model that can efficiently design and verify according to specification changes.

This paper presents design evaluation through the dynamic analysis of gear actuator of Automated Manual Transmission(AMT). The prototype of gear actuator system is designed and implemented systematically, which is composed of an electric motor, ball screw and slider-crank mechanism. Catia program was used to design of gear actuator. RecurDyn program was used to dynamic analysis of gear actuator. Dynamic model of the gear actuator is constructed by using RecurDyn and considering the rotational inertia of every component. As a result, the design of gear actuator was verified through dynamic analysis result. The current research will be a very useful tool in the near future for the dynamic analysis for the gear actuator.

본 논문은 단자대 및 전선 접속부의 불완전 접촉에 의한 아산화동 증식발열에 관한 실험적 연구이다. 아산화동 증식 특성의경우 공급 전류가 증가할수록 증식속도가 가속되어 아산화동 생성물의 크기가 증대되었다. 전선과 단자대의 접촉불량에 따른진동 세기 별 온도특성은 진동의 횟수가 빠를수록 모든 조건에서 용융, 탄화, 아산화동 발생시간이 빠르게 나타났고 1.5 sq 절연전선의 경우 700 rpm, 900 rpm조건에서 접촉불량에 따른 아크에 의한 화염이 발생된 것을 확인할 수 있었다. 세부적으로성분분석을 통해 시료별 특성을 분석해본 결과 아산화동 증식 절연전선의 경우 Cu성분이 증가한 것을 확인할 수 있었으며, 합선에 의한 단락된 절연전선의 경우 Cu성분이 현저히 저하되어 뚜렷한 차이점이 나타났다. This paper presents an experimental study on the proliferative exotherm of copper oxide caused by incomplete contact between the terminal blocks and wire connections. The growth characteristics of copper oxide revealed that the growth rate and size of the copper oxide product increased with an increase in the current supply. As for the temperature characteristics by vibration intensity according to the contact failure between the wire and the terminal block, the faster the number of vibrations, the faster the melting, carbonization, and cuprous oxide generation times under all conditions. For the 1.5 sq. insulated wire, it was confirmed that the flame was generated due to the arc-to-contact mechanism at 700 rpm and 900 rpm. A detailed component analysis on the characteristics of each sample confirmed that the copper content increased in the copper-oxide-proliferated insulated wire. In contrast, the copper content was considerably low in the shorted insulated wire.

This paper deals with the optimization design of plastic gears, which are components of electronic actuators for automobiles. Electronic actuators for automobiles consist of a motor, a reducer, and a controller for controlling the motor. Recently, a conventional steel gear has been replaced by a plastic injection machine. The plastic gear has advantages such as cost, weight, noise reduction, etc. However, there is a problem that the size of the steel gear is increased and the durability is lowered. Therefore, it is necessary to optimize the design of the plastic gear to minimize the disadvantages of the plastic gear, and the safety of the plastic gear should be secured under the maximum operating condition. Structural analysis was performed on the design parameters such as material, module, and thickness of plastic gear to select optimal design parameters under maximum operating conditions. Using the selected design parameters, the stress and the safety factor of the optimally designed plastic gear were confirmed. We will verify the correlation of the analytical model with the future test results and build an analytical model that can efficiently verify the design according to the specification change.
