Underlying Mechanisms

Innenverzahnungen, die aufgrund der Elektromobilität zunehmend im Fokus stehen, lassen sich mithilfe des Wälzschälens produktiv herstellen. Um diese Produktivität weiter zu steigern, müssen die wirkenden Verschleißmechanismen untersucht und verstanden werden. Der Beitrag behandelt die experimentelle Temperaturuntersuchung des Wälzschälens mit anschließender Modellierung der Wärmeverteilung, welche als erster Schritt zum Mechanismenverständnis angesehen werden kann.   Internal gears, which are increasingly in focus due to electromobility, can be manufactured productively with the help of power skiving. In order to further increase the productivity, the wear mechanisms have to be investigated and understood. This paper discusses the experimental temperature analysis of power skiving by subsequently modelling the heat distribution. This process can be seen as a first step towards understanding the underlying mechanisms.

Dissimilar Aluminum Alloys

Microstructural characterization and temperature analysis have been performed in friction stir welding (FSW) of A383 and 5052 dissimilar aluminum alloys. Marked difference in microstructure was observed between joints with different arrangements of materials. The temperature at four points on each side of the joint line was measured during FSW in various conditions. In addition, an analytical model assumed that the work generated by the rotation of the tool led to the work for stirring materials and heat generation of the material and the tool. The temperature of the retreating side (RS) for the joint of the advancing side (AS):A383/RS:5052 was about 50K higher than that of AS, while the temperatures of AS and RS for the joint of AS:5052/RS:A383 were almost the same. The experimental temperature could be calculated reasonably by using the model with assumption of the work for stirring the material.

When cured in a microwave, flat thin composite panels can experience even heat distribution throughout the laminate. However, as load and geometric complexity increase, the electromagnetic field and resulting heat distribution is altered, making it difficult to cure the composite homogeneously. Materials that absorb and/or reflect incident electromagnetic radiation have the potential to influence how the field behaves, and therefore to tailor and improve the uniformity of heat distribution. In this study, an absorber was applied to a composite with non-uniform geometry to increase heating in the location which had previously been the coldest position, transforming it into the hottest. Although this result overshot the desired outcome of temperature uniformity, it shows the potential of absorbing materials to radically change the temperature distribution, demonstrating that with better regulation of the absorbing effect, a uniform temperature distribution is possible even in non-uniform composite geometries.

Collector pipe used in solar power plant is a device for converting water from ambient temperature to the raised temperature which in turn used to rotate turbine blades. The raise in temperature is not that much when compared to thermal or nuclear power plant, so researches are going on for improving the heat carrying capacity of collector pipes. The productivity in pipe directly depends on the factors such as solar radiation incident on it, temperature distribution over the pipe, surrounding temperature, material of the pipeline used, and thickness of the pipe. When comparing to all of such parameters, the temperature distribution over the pipe is the main parameter which determines the performance of the collector pipe. For a particular type of solar collector pipe, the temperature distribution is function of length with day variation of solar incidence over it. In this work a collector pipe of length 2.2 m and 7 cm diameter is fabricated and tested under standard laboratory conditions for the uniform heat dissemination over the pipe. For keeping up the uniform temperature over the collector pipe, it is necessary to wound the pipe with metals like copper, aluminum. The results show that the heat distribution over the pipe is increased in case of copper when compared with aluminium.

The study of heat distribution in laser diode shows that there is nonuniform temperature distribution in cavity length of laser diode. In this paper, we investigate the temperature difference in laser diode cavity length and its effect on laser bar output wavelength width that mounted on usual CS model. In this survey at the first, laser was simulated then the simulations result was compared with experimental test result. The result shows that for each emitter there is difference, about 2.5 degree between the beginning and end of cavity.

This paper presents a new micromachined PCR chip with separable electrodes part and reaction chamber part. The electrodes part, employing Pt film resistor as heaters and sensors, is reusable, and the chamber part is a disposable PDMS-GLASS bonded structure. This PCR chip with reusable electrodes can largely reduce fabrication cost. COMSOL software is used to simulate the temperature distribution of the designed chip and then use infrared thermometer (NEC R300SR) to verify temperature distribution of the fabricated chip. The test results turned out to perfectly fit the simulation of temperature distribution, which provides reliable basis for further PCR amplification experiment.

In this paper, a two-dimensional axisymmetric thermal model using finite element method (FEM) has been established for predicting the temperature distribution profile on the work piece during electro discharge machining (EDM) and obtained material removal rate (MRR) from the temperature isotherm. For prediction of MRR, the model utilizes some important features viz. size and shape of the heat source (Gaussian heat distribution), thermal properties of workpiece, amount of heat distribution among the dielectric fluid, workpiece and tool, material flushing efficiency and pulse off/on time, etc. ANSYS software was used for developing the thermal model for the single spark operation. For this investigation, AISI 304 stainless steel and tungsten carbide was used as workpiece and electrode material, respectively. A comparison study has been carried out for theoretical and experimental MRR for the effect of each process parameter viz. gap voltage, pulse on time and peak current. The temperature distribution along the radial and depth direction of the workpiece has been reported. The model was validated by comparing the theoretical MRR with the experimental MRR and found a good correlation between them.
