Experimental study on combustion and emissions of a compression ignition engine fueled with gasoline
Advances in Mechanical Engineering - Tập 14 Số 7 - 2022
Yan Hu, Zhaoming Huang, Li Wang, Xiaodong Sun, Weiguo Chen
Gasoline compression ignition (GCI) is an effective way to achieve both high thermal efficiency and low emission. The combustion and emission performances of GCI and DCI (diesel compression ignition) were compared on a 2.0 L diesel engine equipped with Three-way catalyst-Lean NOx trap/Passive selective catalytic reduction (TWC-LNT/PSCR) aftertreatment system. In order to further clarify the advant... hiện toàn bộ
Water-Based Fe2O3 Nanofluid Characterization: Thermal Conductivity and Viscosity Measurements and Correlation
Advances in Mechanical Engineering - Tập 4 - Trang 674947 - 2012
Laura Colla, Laura Fedele, Mauro Scattolini, Sergio Bobbo
An experimental investigation on water-based nanofluids containing iron oxide (Fe2O3) in concentrations ranging between 5 and 20% in mass is presented. The purpose of this study is to measure thermal conductivity and dynamic viscosity of these fluids, as a starting point to study the heat transfer capability. The stability of the nanofluids was verified by pH and Zeta potential measurements. A dyn... hiện toàn bộ
Tổng quan về việc tích hợp các cấu trúc lưới gradient nhẹ trong các bộ phận sản xuất theo công nghệ đắp dần Dịch bởi AI
Advances in Mechanical Engineering - Tập 12 Số 6 - Trang 168781402091695 - 2020
Asliah Seharing, Abdul Hadi Azman, Shahrum Abdullah
Bài tổng quan này phân tích thiết kế, hành vi cơ học, khả năng sản xuất, và ứng dụng của các cấu trúc lưới gradient được sản xuất bằng công nghệ đắp dần kim loại. Bằng cách thay đổi các tham số thiết kế như kích thước ô, chiều dài thanh, và đường kính thanh của các ô đơn vị trong cấu trúc lưới, một thuộc tính gradient được hình thành để đạt được các mức độ chức năng khác nhau và tối ưu hóa tỷ lệ g... hiện toàn bộ

Symplectic analysis of stationary random vibration of vehicle–track coupled system with rail-borne electromagnetic generator
Advances in Mechanical Engineering - Tập 10 Số 10 - Trang 168781401880474 - 2018
Mingyuan Gao, Fan Yang, Ping Wang
In this article, the authors establish the vehicle-track coupled model of smart railway track with rail-borne electromagnetic generator and conduct a symplectic analysis in frequency domain. A vehicle-track model considering vehicle traveling load is constructed, and the pseudo-excitation method is used. The frequency-dependent stiffness of rail pad is involved in the calculation model to get accu... hiện toàn bộ
Application of hybrid control algorithm on the vehicle active suspension system to reduce vibrations
Advances in Mechanical Engineering - Tập 16 Số 3 - 2024
Tuan Anh Nguyen, Jamshed Iqbal, Thị Thu Hường Trần, Thang Binh Hoang
This research proposes a hybrid control algorithm to enhance smoothness in a vehicle’s motion. The control signal is synthesized from two separate controllers, Proportional Integral Derivative (PID) and Sliding Mode Control (SMC), to achieve superior control performance. The novelty of the proposed control algorithm lies in using a double-loop algorithm to determine the controller parameters. The ... hiện toàn bộ
Solution of time-fractional Cahn–Hilliard equation with reaction term using homotopy analysis method
Advances in Mechanical Engineering - Tập 9 Số 12 - Trang 168781401774077 - 2017

Development of a lower limb rehabilitation exoskeleton based on real-time gait detection and gait tracking
Advances in Mechanical Engineering - Tập 8 Số 1 - 2016
Chao Zhang, Gangfeng Liu, Changle Li, Jie Zhao, Hongying Yu, Yanhe Zhu
Hemiplegia, apoplexia, or traffic accidents often lead to unilateral lower limb movement disorders. Traditional lower limb rehabilitation equipments usually execute walk training based on fixed gait trajectory; however, this type is unsuitable for unilateral lower limb disorders because they still have athletic ability and initiative walking intention on the healthy side. This article describes a ... hiện toàn bộ
Kinetostatic Analysis of 4-R(CRR) Parallel Manipulator with Overconstraints via Reciprocal-Screw Theory
Advances in Mechanical Engineering - Tập 2 - 2010
Zhen Huang, Yan Zhi Zhao, Jingfang Liu
The paper proposes a new approach based on reciprocal screw theory to analyze kinetostatics of lower-mobility parallel mechanisms with overconstraints and static indeterminacy. For force analysis of parallel mechanisms, the main reactions should be solved firstly, and then all other constraint reactions are easy to be obtained. The approach can remarkably reduce the number of unknowns and keep the... hiện toàn bộ
Determining Commuting Behaviour from Monitoring Technologies
Advances in Mechanical Engineering - Tập 7 Số 1 - 2015
Yuting You, Wei Wang, Min Yang, Russell G. Thompson‬‬
The study of commuting behaviour has always been one significant focus of people to reach comprehensive knowledge of transport-related scenarios. Similarly, commuting behaviour, as one of the four major physical activities people engaged in during daily life, gained much attention in aspect of health fields. This paper, with the sample data collected by The Australian Diabetes, Obesity and Lifesty... hiện toàn bộ
