An Study on the Energy Regeneration System of Boom for Hybrid Hydraulic Excavator |
YU YINGXIAO, Debdattta Das, B. N. M Truong, Kyoung Kwan Ahn(Uinversity of Ulsan, Korea, Republic of ) |
This paper proposes a new hybrid hydraulic excavator boom system and designs a new control strategy. In this system have three modes for boom down.The proposed energy regeneration system is verified through simulation result which is done in the AMESim software. By analyzing simulation result, the proposed system can perform very efficiently. Meanwhile, the proposed system is also compared with conventional one. By comparing and analyzing the simulation results, it seen that the new system has a better efficiency and decrease the energy consumption significantly.prescription discounts cards drug coupons coupons for cialis 2016 coupons for cialis printable click new prescription coupons coupons for cialis printable click new prescription coupons aidamar click aida angebote |

Investigation on optimization the performance of a wave energy converter using Dielectric electro-active polymers |
Phan Cong Binh, Kyoung Kwan Ahn(Ulsan University, Korea, Republic of ) |
This paper investigate the performance of a wave energy converter using Dielectric electro active polymer (DEAP). Firstly, the model of conventional DEAP generator is presented and validated by a simple test rig. Then, an antagonistic DEAP generator so-called energy capture unit (ECU) consists of two DEAP in antagonistic connection mode is analyzed and modeled. In order to increase the output energy, a new design of WEC is then developed with array of ECU. Moreover, the hydrodynamic forces are calculated under regular wave conditions by using the linear potential wave theory.

This paper presents a neural networks model (NNM) and for modeling and identifying the nonlinear behavior of a fish robot. Firstly, a set of driving moment signals were applied to the fish robot in order to investigate the fish robot operation. Consequently, a neural networks model was constructed and an identification scheme based on Genetic Algorithm was developed. Validation results proved the ability of proposed scheme to tracking the descent operation of the fish robot. The combination of PID controller and NNM was implemented and successfully control fish robot follow given trajectories.cialis discount coupons go cialis price check lilly cialis coupon click drug coupon ciprofloxacin go cipromed |

A study on wave energy converter using 5 cylinders system |
Tri Dung Dang, Kyoung Kwan Ahn(University of Ulsan, Korea, Republic of ), Phan Cong Binh(Ulsan University, Korea, Republic of ) |
Nowadays, wave energy plays an important role in renewable energy resource. In over thirty years, researches in wave energy converter system (WEC) have been deployed and carried out. This paper presents a design of wave energy converter using 5 cylinders combining with hydraulic power take-off system in order to convert the mechanical energy from ocean wave to electricity, or another useful and usable source. The WEC uses ordered 5 cylinders to represent the motion of the floating buoy under the wave elevation.what is the generic name for bystolic click bystolic savings card program prescription drugs coupon eblogin.com cialis coupons 2015 lilly cialis coupon click drug coupon prescription discounts cards read coupons for cialis 2016 |

A Novel Energy Recuperation System for Hybrid Excavator using Hybrid Actuator |
Debdatta Das, Puja Chowdhury, B. N. M Truong, KyoungKwan AHN(University of Ulsan, Korea, Republic of ) |
At present, with the development of world economic compression, the cost of energy has grown dramatically. So hybrid system is one of the better solution. As a result, this paper predominantly investigates the energy recuperation system. A power storage component, electrical battery, is combined with a hybrid actuator using an electric motor and an electrical generator as energy convention component. In cementation, a controlling strategy and to optimize the energy saving, is also proposed. The measures to improve the energy recuperation efficiency of the proposed system are presented.bystolic generic link bystolic coupons for free type 2 diabetes signs diabetes treatment ciprofloxacin go cipromed ciprofloxacin go cipromed |

Research on Energy Regeneration and Effect of Dynamic Characteristics of Secondary Control Swing for Hydraulic Excavator System |
Puja Chowdhury, Dabdatta Das, B. N. M Truong , KyoungKwan AHN(University of Ulsan, Korea, Republic of ) |
The rotating movement of excavator is called swing or slew and is driven hydraulically.In the proposed system, swing braking time the remaining fluid will save as energy by a simple accumulator.The proposed system is considered as secondary by using two combination of transformer (motor & pump combination) and have some dissimilarities from the conventional one.Furthermore, the paper simulates variable inertia and show the effect of variable moment of inertia in different simulation result.The proposed system will be more efficient in saving energy.prescription discounts cards drug coupons coupons for cialis 2016 coupons for cialis printable click new prescription coupons ciprofloxacin go cipromed |
