Abstract

The sound quality of a gong is influenced by its dynamic characteristics (its structural eigenmode). By controlling natural frequency ratio of the gong to a certain value, we can expect to obtain the optimum gong design. The subject of the present research is to establish an analysis of the application of design optimization in obtaining an optimum gong design. The optimum gong is defined as a gong that has a certain natural frequency ratio. The natural frequency ratio adopted in this reseach is based on those of English bell [1]. The Sequential Unconstrained Minimization Techniques from Ansys 5.4 is used to perform the optimization process. The design optimization method has been successfully applied on the optimization of the gong. The results obtained from the three case studies show that the most sensitive part of the gong is at its around free end. This indicates that in manufacturing gong, this part must be carefully treated.

Abstract

Axle Lining is a type of journal bearing at wheel driver shaft in which makes locomotive traction motor possible to be supported on the mover shaft. According to hydrodynamic lubrication theory, journal bearing is designed to work under hydrodynamic lubrication condition. Film layer between journal and bearing surfaces can give less contact between those surfaces. When the bearing is working, all performance parameters such as minimum film thickness, eccentricity ratio, bearing friction coefficient, lubricant flow, maximum lubricant pressure, temperature rise of lubricant, have to be achieved thus the bearing can reach the desired life and performances. Impact load, which works to bearing, is one important factor to be noticed because it can affect bearing performance comprehensively. Using numerical Raimondi and Boyd method which developed in form of computer program, the process to determine journal bearing performance calculation can be easier and give more accurate result. The application of this method for the calculation performance import and local product show that imported journal bearing work under hydrodynamic condition for low value of impact load up to 1500 lbf (6,68 kN). Local product work under elastohydrodynamic condition for low value of impact load up to 1000 lbf (4,45 kN). Critical impact load is 1500 lbf (6,68kN) for both product which calculated using Trumpler criteria .

Abstract

Cement calsiner is a reactor where the decarbonization of lime stone and fuel combustion processes take place simultaneously. Decarbonization of lime stone is endothermic process and uses the heat produced by the combustion of fuel. However, because these two simultaneous processes produce CO2, the effectiveness of both processes depend on the CO2 concentration along the gas stream inside the calciner. The complexity of these simultaneous processes causes the variation of calciner design that could be found in cement industry. Especially for the calciner using coal as a fuel, this variation design influences significantly to the operation of the calciner. This paper presents a comparison study of design and operational parameters of some calciners in Indonesian cement manufacturers. The result of study could be used for designers to consider some principal parameters during design process so that the calciner could operate properly and give a better performance.

Abstract

Energy absorbing structural components are widely used in vehicles, such as car, aircraft, train, ships and others. The aim is to absorb energy during impact and thus lessen the risk of occupant's injuries and limit the damage to the whole structure. Cylindrical shell that deform plastically due to longitudinal loading is one of the efficient energy absorbing structures. In this paper, experiments were carried out on aluminum cylindrical shell which was loaded axially. The diameters of the cylindrical shell were 60 mm and 100 mm, and the thickness was 2 mm. Some collapse trigger mechanisms were investigated, which are: plastic fold trigger, circular hole trigger and oval hole trigger. The experiments will then be compared with analytical results.

Abstract

The application of crashworthiness technology to a vehicle has a main objective of protecting the passenger or cargo from the effects of impact/collision. One of the strategies is by using impact energy absorbing (IEA) modules. Two of the alternatives of IEA modules are metallic tubes with internal inversion and controlled axial splitting mechanism. This paper presents both numerical and experimental approaches to understand the characteristics of the two mechanisms, before using them in design phase. LS-Dyna was used as the numerical simulation software for drop test case. The result of simulation is presented as the relationships between geometrical parameters and the crashworthiness parameters, e.g. impact energy and response force. Some cases are compared with quasi-static and drop test results.
