A study of the LCF characteristics of the Ni-based superalloy IN738LC
International Journal of Precision Engineering and Manufacturing - Tập 16 - Trang 775-780 - 2015
In this study, low cycle fatigue (LCF) tests of IN738LC were conducted under high-temperature conditions. The tests were performed with various mechanical strain amplitudes and the relationship between strain amplitude and fatigue life was obtained. In addition, an equation for LCF life prediction was derived from the test results. After obtaining a strain-life diagram from the LCF test results, a...... hiện toàn bộ

Optimization of Variable Blank Holder Force Based on a Sharing Niching RBF Neural Network and an Improved NSGA-II Algorithm
International Journal of Precision Engineering and Manufacturing - Tập 20 - Trang 285-299 - 2019
Variable blank holder force (VBHF) is an important process parameter in sheet metal forming. The purpose of this study is to propose a sharing niching radial basis function (SNRBF) neural network for VBHF optimization. Two methods are put forward to improve the prediction accuracy of a RBF neural network. (1) A RBF neural network is trained by a sharing niching technique to achieve global optimal ...... hiện toàn bộ
A Gain-Adaptive Intelligent Nonlinear Control for an Electrohydraulic Rotary Actuator
International Journal of Precision Engineering and Manufacturing - Tập 19 - Trang 665-673 - 2018
This paper introduces an effective approach for trajectory-tracking control of an electrohydraulic rotary actuator (EHRA). The key feature of this control approach is to utilize a gain-adaptive fuzzy sliding mode control technique to realize the control objective wherein the mathematical model of the system dynamics does not need to be known exactly. Firstly, a state space form of the system model...... hiện toàn bộ
Development of warm forming parts for automotive body dash panel using AZ31B magnesium alloy sheets
International Journal of Precision Engineering and Manufacturing - Tập 16 - Trang 2159-2165 - 2015
According to current development trends for automotive parts, light-weight is a key issue in improving fuel efficiency and CO2 reduction. Compared to steel and aluminum, magnesium has a relatively low specific gravity. However, it is challenging to use magnesium to produce a product at room temperature because magnesium has a hexagonal close-packed crystal structure. Therefore, the structure is no...... hiện toàn bộ
Investigation of tension force in stretch forming of doubly curved aluminum alloy (Al5083) sheet
International Journal of Precision Engineering and Manufacturing - Tập 17 - Trang 433-444 - 2016
Aluminum alloys, which are suitable for lightweight applications, are being applied widely in diverse industries, especially to the external bodies of automobiles, ships, and aircraft. The external bodies of these vehicles have a three-dimensional geometric shape with various double curvatures. However, aluminum sheets with double curvatures are difficult to form because of their elastic recovery ...... hiện toàn bộ

Effect of contact angle between retaining ring and polishing pad on material removal uniformity in CMP process
International Journal of Precision Engineering and Manufacturing - Tập 14 - Trang 1513-1518 - 2013
This paper presents the effect of the contact angle between the retaining ring and the polishing pad in chemical mechanical polishing (CMP) on the profile of the material removal rate (MRR) around the wafer edge and on the within-wafer nonuniformity (WIWNU). This study demonstrates that the mechanical interaction among the polishing pad, wafer, and retaining ring influences the ability to achieve ...... hiện toàn bộ
