Abstract:

Abstract. A ratchet is an essential component of the ratchet pawl mechanism. But the traditional ratchet strength check method has certain limitations in the design process. In this paper, the stress analysis of the ratchet is discussed and a precision mathematical model for the ratchet tooth root bending stress is proposed for the first time. This model was established by the folded section and defined by the incision effect theory. To test the prediction ability of the proposed mathematical model, the maximum stress of three standard ratchets and one non-standard ratchet were analyzed by the

To test the difference in loading and unloading forces delivered by six coated nickel-titanium wires and their non-coated equivalents. Commercially available six coated nickel-titanium wires and their non-coated equivalents of sizes 0.016-inch diameter round and 0.016 X 0.022-inch rectangular cross-section were procured. The wires were evaluated using a three-point bending test based on the method in ISO Standard 15841. No statistically significant differences in force values were found between coated and non-coated wires, listed by deflection in three-point bending, for these specific groups.

Abstract:

Shielded Metal Arc Welding (SMAW) is a popular welding technology in the construction and industrial sectors due to its ease of use. Flux-cored arc welding (FCAW) has gained popularity in the construction sector and industrial settings. The Welding Procedure Specification (WPS) restricts material compatibility for FCAW due to systematic selection and qualification. Penetrant Testing exposes damage to welded specimens, ensuring they meet the standard. Non-Destructive Testing (NDT) and mechanical tests like tensile and bending tests determine the mechanical strength and weld characteristics of s

The screen analysis results on decarburized fly ash shows that the content of +45 μm is above 12 %, failing to meet the quality of Grade I fly ash determined in the standard of China. Therefore, the decarburized fly ash was processed by grinding to meet the required quality. The analysis of the main constituents of different grinding methods conducted for tail fly ash shows that fly ash obtained by open circuit ball mill are the most suitable one

Abstract:

Cast iron material is a material that has brittle properties and is less able to withstand stress due to the welding cycle caused by flake graphite in cast iron. Because of these problems, in connecting cast iron materials using the SMAW welding method, it is necessary to have heat treatment (preheating) to avoid the welding problems on the properties of cast iron. The purpose of this study is to determine the effect of heating and non-heating on the cast iron before the welding process. Therefore, this research will play a crucial contribution as a reference for cast iron welding researchers

This paper presents partial discharge (PD) investigation of different cable termination defects. The medium voltage power cables as rated of 3.6/6(7.2) kV are applied. Finite Element Method Magnetic (FEMM) program is used as a simulation tool for electric field stress investigation. The partial discharges patterns are detected by using a commercial High Frequency Current Transformer (HFCT). The simple cases for internal, surface and corona discharge are firstly observed in order to investigate the performance of the HFCT. Then eight different case studies of cable termination defects are furth

Previous studies have shown that thermally modified wood (TMW) performs well in outdoor, above-ground conditions in terms of resistance to wood-decaying fungi. Yet, little is known about the development of defects such as checks and the corresponding mechanical properties of TMW in this condition. This experiment focused on the effect of 30 months outdoor above-ground exposure (weathering) on the degree of checking, dynamic stiffness and static bending properties of thermally modified timber (TMT) of Norway spruce.

As long as non-contact digital printing remains an uncommon standard in the corrugated packaging industry, corrugated board crushing remains a real issue that affects the load capacity of boxes. Crushing mainly occurs during the converting of corrugated board (e.g., analog flexographic printing or laminating) and is a process that cannot be avoided. However, as this study shows, it can be controlled. In this work, extended laboratory tests were carried out on the crushing of double-walled corrugated board.

Digital gradient sensing (DGS) is a non-contact and full-field optical measurement technique, which assesses mechanical behaviors of transparent materials or specular structures by measuring angular deflections of light rays. However, owing to the poor light-gathering capability of its imaging system, the dynamic performance of DGS is heavily restricted. Here, a method of enhancing the dynamic performance of DGS by improving its speckle target is proposed. The method employs the technique of backlight illumination, which significantly increases the utilization efficiency of light, shortens the

The use of threaded connection is a valuable alternative to conventional welding in tubularconstructions, e.g. pipelines, drill pipes and deep water risers. Those applications are normally exposed toenvironmental hazards – wave induced vibrations, temperature changes, etc. – as well as subjected tosevere service conditions. A classical way to determine fatigue strength in many engineering situations is tocalibrate material models by means of ad hoc designed experiments. Unfortunately, it is very difficult in thiscase even under laboratory conditions due to complicated stress and strain states

The lack of these guidelines is also one of the reasons the results obtained in numerous research are often fluctuating, and we cannot draw clear conclusions.
