Pengauruh Sudut Camber Roda Depan pada kemampuan Belok Mobil Model 4 dan 2 Roda penggerak (4WD dan RWD)
2013Co-Authors: Dewanto Joni, Efendi DickyAbstract:Beberapa ahli telah melakukan penelitian tentang dinamika dan stabilitas kendaraan melalui beragam pemodelan dan simulasi. Paper ini mengemukakan penelitian yang berbasis eksperimen mengenai pengaruh sudut Camber roda depan pada kemampuan belok mobil 4 roda. Pengujian dilakukan pada mobil remote control sebagai model mobil 4 dan 2 roda belakang penggerak dengan variasi kecepatan mobil dan sudut Camber roda depan. Hasil penelitian menunjukkan bahwa sudut Camber roda depan negative dapat berdampak menurunkan kemampuan belok mobil baik jenis 4 roda penggerak maupun 2 roda penggerak belakang. Mobil dengan 4 roda penggerak menunjukkan kemampuan belok yang lebih baik dari pada mobil dengan 2 roda penggerak belakang. Kemampuan belok mobil terbaik dicapai jika sudut Camber roda depan diset sebesar 0

improvement of vehicle handling performance due to toe and Camber angle change of rear wheel by using double knuckle
Transactions of the Korean Society of Automotive Engineers, 2013Co-Authors: Jeonghyun Sohn, Seongjun ParkAbstract:In this study, suspension geometry is controlled to improve vehicle handling performance. The toe and Camber of the rear suspension is controlled independently by using a double knuckle structure designed to enhance the vehicle cornering stability. Camber and toe changes in the rear wheel during high speed turning maneuver are important factors that influence the vehicle stability. Toe in the rear outer wheel plays a dominant role in cornering. A control algorithm for the Camber and the toe angle input is developed to carry out the control simulation of the vehicle such as single lane change, the steady state cornering, the double lane change and the step steering simulation. Effects of the Camber and toe angle control are analyzed from the computer simulations. A double lane change simulation revealed that the suspension mechanism with variable Camber angle and variable toe angle decreases the peak body slip angle and peak yaw rate, 50% and 10%, respectively.

effects on vehicle handling performance according to Camber angle change of front and rear wheel
Transactions of the Korean Society of Automotive Engineers, 2011Co-Authors: Seongjun Park, Jeonghyun SohnAbstract:In this study, a Camber angle generating mechanism for front and rear suspension is suggested. An experimental device is implemented and tested. A full vehicle model with Camber angle generating device by using ADAMS/Car is modeled. Step steer simulations are carried out for investigating the effects of vehicle handling performance due to Camber angle change of front and rear wheel. According to results, the Camber angle of rear suspension affects the vehicle handling performance during both simulations. Therefore, when the vehicle makes the right turn or left turn, left and right wheel of front and rear suspension should have the proper orientation for improving the handling performance, respectively.

analysis of vehicle handling performance due to Camber angle change of rear wheel
Transactions of the Korean Society of Automotive Engineers, 2010Co-Authors: Seongjun Park, Jeonghyun SohnAbstract:In this study, a Camber angle generating mechanism for rear suspension is suggested. An experimental device is implemented and tested. A full vehicle model with Camber angle generating device by using ADAMS/Car is modeled. Rear left wheel and rear right wheel have 5 different Camber angles in the simulations, respectively. Step steer and pulse steer simulations are carried out for investigating the effects of vehicle handling performance due to Camber angle control of rear suspension. According to the results, the Camber angle of rear suspension affects the vehicle handling performance during both simulations. Therefore, when the vehicle makes the right turn or left turn, left and right wheel should have the proper orientation for improving the handling performance, respectively.

anterior chamber depth after posterior chamber intraocular lens implantation
Acta Ophthalmologica, 2009Co-Authors: Mikki Arai, Iwao Ohzuno, Masahiro ZakoAbstract:The precise behavior of the anterior chamber depth after intraocular lens implantation is uncertain. To ascertain variations in the values at different time points, we measured the anterior chamber depth in 38 eyes that had undergone extracapsular cataract extraction and posterior chamber intraocular lens implantation. Measurements were performed by ultrasonography preoperatively and at 2 days, 1 and 2 weeks postoperatively, and at 1-month intervals thereafter up to 10 months (mean follow-up period, 9 months). Results showed that two peaks of the anterior chamber depth occurred at 1 week and 3 months postoperatively (means +/- SD, 3.54 +/- 0.39 and 3.59 +/- 0.43 mm, respectively). A significant difference was found between the values measured preoperatively (3.29 +/- 0.57) and at 2 days postoperatively (3.33 +/- 0.39) and the 1-week postoperative value (p < 0.05, using the one-way analysis of variance test). A significant difference also was found between the preoperative and the monthly measurements and the 3-month postoperative measurement (p < 0.05). We also calculated the refractive error and found that during the second postoperative week, the refraction tended toward higher myopia that became more hyperopic 3 months postoperatively. This anterior chamber depth variation may cause variations in vision after cataract surgery with intraocular lens implantation.
