    Response and Failure of Elliptical Tubes With Different Long/Short Axis Ratios Under Cyclic Bending

    by Min-Cheng Yu and We n-Fung Pan

    Abstract

    This paper investigates the response and failure of SUS304 stainless steel elliptical tubes with four different long/short axis ratios (1.5, 2.0, 2.5, and 3.0) under cyclic bending. The wall thickness is 0.7 mm for all elliptical tubes, and cyclic bending loads are applied until buckling failure occurs. The experimental moment-curvature relationships exhibit cyclic hardening and form stable loops for all long/short axis ratios. An increase in the long/short axis ratio results in a slight decreas...

    Copper-Reduction Alloy Design for Brake Pads

    by Tzung-Ming Chen and Chung-Jia Huang

    Abstract

    In this study, a copper-reduction brake pad was designed based on environmental considerations. Solid diffusion calculations were performed for the brake pads containing 35 wt.% copper and 15 wt.% nickel. Functional alloy elements were added to the brake pads using a powder metallurgy process to achieve the desired results. The effect of each component on the mechanical properties of the pad was studied by adjusting the alloy ratio in the specimens. The binding behaviors of the copper substrate ...

    A Method of Reducing Tolerance Stack-Up For Parts Assembling of Molds

    by Yuo -Tern Tsai and Chun-Sheng Chen

    Abstract

    Allocating appropriate tolerance to the components to meet the functional requirements of products is an important task in the design phase. This article introduces the methods of tolerance analysis including tolerance marking for improving the assembly precision for injection molds. The influences of modification symbols of geometric tolerance are reported to support tolerance designing. The dimensional chains of the mold are constructed for performing tolerance analysis and design improvements...

    Evaluating the Impact of Afterburner and Reformer on the Power Generation and Efficiency of SOFC

    by Yen-Hsin Chan

    Abstract

    This study establishes a system loop analysis model for SOFC systems incorporating thermal components through thermodynamic theory. The model can be used to evaluate the overall efficiency, power generation, and operating status of components in SOFC systems under different operating conditions. Additionally, using a commercial stack module, the study completes the analysis of afterburner temperature and the effects of using SR and ATR reformers on the temperature, power generation, and efficien...

    Development of the Airtightness Experimental Device for Diving Suit

    by Guoqing Gong, Youmin Wang and Peng Gong

    Abstract

    At the present time, the airtightness testing method of diving devices is comparatively backward, with complicated and inefficient operation of testing devices, which has failed to ensure the airtightness of each diving suit. Regarding the fundamental research and development of the diving suit airtightness testing device, this paper determined the control scheme with the clamping force servo control as the core, drew the 3D model of the clamping and sealing module of the airtightness testing de...

    Design and Control System Research of Hydraulic Pressure Test Bench

    by Xu Fang, Youmin Wang and Lili Zhang

    Abstract

    For the existing hydraulic pressure servo system test bench overall performance is poor. This paper takes the hydraulic pressure servo valve-controlled symmetric hydraulic cylinder closed-loop force control system as the research object. The design of the hydraulic control system and the calculation and selection of hydraulic components are completed. It is proposed to take the error force between the input and output of the system as the optimization objective to obtain the global optimal worki...

    Research On the Fault Detection Method of Centrifugal Pump Rotor Misaligned

    by Yechun Li, Lingfeng Tang and Weiwei Duan

    Abstract

    Aimed at the problems of low detection accuracy and poor adaptability of centrifugal pump rotor misalignment fault, the mechanism and characteristics of centrifugal pump rotor misalignment fault were discussed. The overall scheme design of the centrifugal pump rotor misalignment fault diagnosis was completed. The vibration state of rotor stability and misalignment fault was simulated, and the time domain curve, order spectrum, and axis trajectory diagram under different states were obtained. A f...

    Experimental and Numerical investigation of the Cooling Process in Greenhouse Microclimate During the Summer Season

    by Abid Hasna , Ahmed Ketata , Mariem Lajnef , Hamza Chiboub and Zied Driss

    Abstract

    The paper conducts a thorough analysis of the impact of the local four-season climate on greenhouse conditions, with a focus on high temperatures during the summer. A numerical study addresses the cooling processes, considering the Reynolds number effect and the influence of the shade screen on indoor temperature. Experimental setups and numerical models are employed, validated through comparisons with greenhouse prototype data. Four Reynolds number values are examined for their impact on airflo...

    RSM-Based Modelling and Optimization of Performance Measures for WEDM of Inconel 706

    by Jwala Parshad , Vivek Aggarwal and Neelkanth Grover

    Abstract

    Superalloy machining is a significant research concern due to the widespread increase in demand for this category of materials and specific issues with its machining. Due to its easy fabrication, excellent mechanical strength and outstanding high temperature capability, the Inconel 706 superalloy has become more popular than Inconel 718 in the gas turbine industry. Majority of the gas turbine elements have intricate shapes and requires high accuracy, high precision and excellent surface quality....
