Modelica-based object-orient modeling of rotor system with multi-faults
Chinese Journal of Mechanical Engineering - Tập 26 - Trang 1169-1181 - 2013
Ming Li, Yu Wang, Fucai Li, Hongguang Li, Guang Meng
Modelica-based object-orient method is proved to be rapid, accurate and easy to modify, which is suitable for prototype modeling and simulation of rotor system, whose parameters need to be modified frequently. Classical non-object-orient method appears to be inefficient because the code is difficult to modify and reuse. An adequate library for object-orient modeling of rotor system with multi-faul...... hiện toàn bộ
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
Determination of elastoplastic mechanical properties of the weld and heat affected zone metals in tailor-welded blanks by nanoindentation test
Chinese Journal of Mechanical Engineering - Tập 28 - Trang 911-918 - 2015
Xiangdong Ma, Yingping Guan, Liu Yang
The elastoplastic mechanical properties of the weld and heat affected zone metals have comparatively major impact on the forming process of tailor-welded blanks. A few scholars investigated the elastoplastic mechanical properties of the weld and heat affected zone, but they only simply assumed that it was a uniform distribution elastoplastic material different from the base materials. Four types o...... 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
Objective evaluation method of steering comfort based on movement quality evaluation of driver steering maneuver
Chinese Journal of Mechanical Engineering - Tập 27 - Trang 1027-1037 - 2014
Yiyong Yang, Yahui Liu, Man Wang, Run Ji, Xuewu Ji
The existing research of steering comfort mainly focuses on the subjective evaluation, aiming at designing and optimizing the steering system. In the development of steering system, especially the evaluation of steering comfort, the objective evaluation methods considered the kinematic characteristics of driver steering maneuver are not proposed, which means that the objective evaluation of steeri...... 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
Modeling and compensation technology for the comprehensive errors of fixture system
Chinese Journal of Mechanical Engineering - - 2012
Gaiyun He, Binbin Yang, Baihui Ding, Hongyang Jia
Combined Cellular Automaton Model for Dynamic Recrystallization Evolution of 42CrMo Cast Steel
Chinese Journal of Mechanical Engineering - Tập 31 - Trang 1-11 - 2018
Yi-Na Guo, Yong-Tang Li, Wen-Yan Tian, Hui-Ping Qi, Hong-Hong Yan
The dynamic recrystallization (DRX) simulation performance largely depends on simulated grain topological structures. However, currently solutions used different models for describing two-dimensional (2D) and three-dimensional (3D) grain size distributions. Therefore, it is necessary to develop a more universal simulation technique. A cellular automaton (CA) model combined with an optimized topolo...... hiện toàn bộ
