Optimization of Uncertain Structures with Interval Parameters Considering Objective and Feasibility Robustness
Chinese Journal of Mechanical Engineering - Tập 31 - Trang 1-13 - 2018
Jin Cheng, Zhen-Yu Liu, Jian-Rong Tan, Yang-Yan Zhang, Ming-Yang Tang, Gui-Fang Duan
For the purpose of improving the mechanical performance indices of uncertain structures with interval parameters and ensure their robustness when fluctuating under interval parameters, a constrained interval robust optimization model is constructed with both the center and halfwidth of the most important mechanical performance index described as objective functions and the other requirements on th...... hiện toàn bộ
Deep Learning Based Data Fusion for Sensor Fault Diagnosis and Tolerance in Autonomous Vehicles
Chinese Journal of Mechanical Engineering - Tập 34 - Trang 1-11 - 2021
Huihui Pan, Weichao Sun, Qiming Sun, Huijun Gao
Environmental perception is one of the key technologies to realize autonomous vehicles. Autonomous vehicles are often equipped with multiple sensors to form a multi-source environmental perception system. Those sensors are very sensitive to light or background conditions, which will introduce a variety of global and local fault signals that bring great safety risks to autonomous driving system dur...... hiện toàn bộ
Effect of geometrical parameters on submerged cavitation jet discharged from profiled central-body nozzle
Chinese Journal of Mechanical Engineering - Tập 26 Số 3 - Trang 476-482 - 2013
Mao Yang, Shengnan Xiao, Can Kang, Yuli Wang
Delamination Testing of AlSi10Mg Sandwich Structures with Pyramidal Lattice Truss Core made by Laser Powder Bed Fusion
Chinese Journal of Mechanical Engineering - Tập 34 - Trang 1-12 - 2021
M. Nuño, J. Bühring, M. N. Rao, K. -U. Schröder
Sandwich structures possess a high bending stiffness compared to monolithic structures with a similar weight. This makes them very suitable for lightweight applications, where high stiffness to weight ratios are needed. Most common manufacturing methods of sandwich structures involve adhesive bonding of the core material with the sheets. However, adhesive bonding is prone to delamination, a failur...... hiện toàn bộ
Type Synthesis of Lower Mobility Parallel Mechanisms: A Review
Chinese Journal of Mechanical Engineering - Tập 32 - Trang 1-11 - 2019
Wei Ye, Qinchuan Li
Type synthesis of mechanisms aims to systematically determine all possible structures for a specific mobility requirement. Numerous methods based on different theories were proposed for type synthesis of lower mobility parallel mechanisms in past decades. However, there does not exist a comprehensive review on these approaches. Therefore, the goal of this paper is to give such a review, classifyin...... hiện toàn bộ
Analysis of oil consumption in cylinder of diesel engine for optimization of piston rings
Chinese Journal of Mechanical Engineering - Tập 26 - Trang 207-216 - 2013
Junhong Zhang, Guichang Zhang, Zhenpeng He, Jiewei Lin, Hai Liu
The performance and particulate emission of a diesel engine are affected by the consumption of lubricating oil. Most studies on oil consumption mechanism of the cylinder have been done by using the experimental method, however they are very costly. Therefore, it is very necessary to study oil consumption mechanism of the cylinder and obtain the accurate results by the calculation method. Firstly, ...... hiện toàn bộ
Quasi-static analysis of thrust-loaded angular contact ball bearings part I: theoretical formulation
Chinese Journal of Mechanical Engineering - Tập 25 - Trang 71-80 - 2012
Wenhua Chen, Zikui Ma, Liang Gao, Xinglin Li, Jun Pan
Ball bearings play an important role in various rotating machineries, but the complicated kinematic and tribological features of ball bearings make many aspects of their operating behaviors still inconclusive. Most theoretical analyses of ball bearings up to date are based on either the hypothesis of race control or other empirical models to determine the ball motion of ball bearings, but none of ...... hiện toàn bộ
Preparation of Nickel-Cobalt/Carborundum Carbide Composite Coatings by Supergravity Field-Enhanced Electrodeposition
Chinese Journal of Mechanical Engineering - Tập 33 - Trang 1-10 - 2020
Xiaoyun Hu, Ningsong Qu
Nickel-cobalt/silicon carbide (Ni-Co/SiC) composite coatings were fabricated by supergravity field-enhanced electrodeposition. The surface morphology and the distribution of the SiC particles in the coatings were examined by scanning electron microscope and energy dispersive X-ray spectrometry. The preferred orientations of the coatings were measured by X-ray diffractometry. The wear resistance an...... hiện toàn bộ
Study of ss-DNA Adsorption and Nano-mechanical Properties on Mica Substrate with Surface Forces Apparatus
Chinese Journal of Mechanical Engineering - Tập 31 - Trang 1-8 - 2018
Gui-Bin Shen, Ya-Jing Kan, Min-Hua Chen, Yun-Fei Chen
Many DNA-based devices need to build stable and controllable DNA films on surfaces. However, the most commonly used method of film characterization, namely, the probe-like microscopes which may destroy the sample and substrate. Surface Forces Apparatus (SFA) technique, specializing in surface interaction studies, is introduced to investigate the effects of DNA concentration on the formation of sin...... hiện toàn bộ
Optimization study on a single-cylinder compressed air engine
Chinese Journal of Mechanical Engineering - Tập 28 - Trang 1285-1292 - 2015
Qihui Yu, Maolin Cai, Yan Shi, Qiyue Xu
The current research of compressed air engine (CAE) mainly focused on simulations and system integrations. However, energy efficiency and output torque of the CAE is limited, which restricts its application and popularization. In this paper, the working principles of CAE are briefly introduced. To set a foundation for the study on the optimization of the CAE, the basic mathematical model of workin...... hiện toàn bộ
