Abstract

Penyambungan dengan menggunakan kampuh bilah ganda dan baut atau rivet umumnya digunakan pada plat utama yang mempunyai beban yang besar. Kerusakan yang terjadi pada kampuh bilah ganda terjadi pada plat sambungan atau rivet karena adanya gaya eksternal berupa tarikan. Tegangan yang terjadi akan mermbat pada lubang plat atau rivet yang memiliki perubahan geometri. Telah dilakukan sebuah penelitian untuk mengetahui sifat mekanik material pelat yang dikenai gaya tarik sebesar 25 KN dengan arah horisontal, Material uji yang akan disimulasikan adalah material structural st 37 dengan kekuatan tarik luluh 362 MPa untuk material plat atau kampuh penyambung. Materil rivet menggunakan st 30 dengan kekutan tarik sebesar 290 MPa dan untuk materil plat utama menggunakan AISI 1045 C dengan kekuatan tarik sebesar 450 Mpa. Simulasi ini menggunakan Software Ansys. Untuk ukuran Diameter rivet yang digunakan dalam simulasi ini adalah ada 3 jenis yaitu Dr = 12 mm, 14 mm dan 16 mm sedangkan untuk tebal kampuh tp = 6 mm, 8 mm dan 10 mm. Tegangan maksimum yang terjadi pada kampuh atau rivet lebih kecil dibandingkan dengan tegangan yang terjadi pada plat utama. Sehingga kemungkinan terjadi kegagalan lebih besar pada plat utama. Untuk rivet yang dengan ukuran diameter 12 mm dan ketebalan kampuh 6 mm tegangan maksimum yang terjai masih dibawah tegangan plat utama.

Abstract

The coil type heat exchanger is one of the important parts in the process of transferring heat from the exhaust heat to the water. This coil type heat exchanger has not been widely used in combustion exhaust gases. Heat transfer from gas to water in the coil is carried out by conduction and convection along the exhaust. The heat received by the water in the coil will change the liquid phase into steam and then the water vapor will naturally move to flow in the heat exchanger. The volume of water in the coil is half of the volume of the coil heat exchanger pipe. From the results of my research and simulations, the water in the water tank can be heated up to 82 oC. This heat exchanger is able to transfer heat from the hot water coming out of the heat exchanger in the exhaust into the water in the water tank (shell) as much as 2 liters. The final result of the calculation required a heat flow rate of 158.13 Watt.

Abstract

Beam splicing using butt joints is one of the most common forms of connection found in the construction of bridges, towers or other structures. The size of the connection used is adjusted to the ability of the base material, the existing external load and the material of the seam and rivet itself. The number of rivets used must also be adjusted to the load to be supported. If the number of rivets used is too much, it will also cause stress on the connection itself. Due to the complicated combination of the two elements, namely the seam and the diameter of the rivet used, everyone can determine the size at will regardless of the stress propagation on the seam or rivet. In this study, the authors analyzed the effect of the combination of hole diameter and the distance between holes on the strength of the connection at stack connection. Based on the results of research that has been carried out on a double blade seam plate with variations in the thickness of the seam and the diameter of the rivet. The maximum stress that occurs on the seam or rivet is smaller than the stress on the main plate. So the possibility of failure is greater on the main plate. For rivets with a diameter of 12 mm and a seam thickness of 6 mm, the maximum stress that occurs is still below the main plate stress. At the rivet diameter of 16 mm, the stress began to increase sharply on the main plate and the seam. The decrease in the cross- sectional area due to the increase in the diameter of the rivet increases the stress generation. For connection and rivet safety factors, the average is above 7 and the condition is very safe. This safety factor is also greatly influenced by the distance between the holes and the thickness of the seam plate used. The greater the decrease in the normal surface area, the lower the safety factor.

Abstract

Fish drying machine with a capacity of 50 kg of wet fish is one of the energy machines that serves to reduce the water content in fish by passing hot air of 40-50oC above its surface. This fish drying machine has a heat exchanger as its main heart. The source of heat energy used is the combustion of husks and air. Then with the heat exchanger the gas is flowed through the tube in the heat exchanger. The heat exchanger used is a cross flow type heat exchanger in which the air fluid mixes and the husk combustion gases do not mix. On the outside of the tube, drying air flows which will be heated and used as a drying medium for wet fish. The large heat flow rate carried by the drying air can reduce the water content in the grain by 31.2 kg of water from 50 kg of fresh fish in 8 hours. The heat exchanger construction planning is made in such a way using the LMTD approach and the effectiveness and CFD simulation integrated in Anys15.0, so that the performance of the tool can be known. The final result of modeling provides flow and temperature distribution that occurs in the heat exchanger. The capital uses 3D steady flow by selecting standard K-e as turbulence modeling and activating the energy equation. The input data entered into the application is the result of previous measurements and calculations.
