Abstract

Perkembangan ilmu pengetahuan dan teknologi khususnya dalam bidang permesinan dan elektronika telah membawa perubahan besar dalam tatanan kehidupan manusia, seperti untuk menciptakan suatu proses pengerjaan yang cepat untuk menghasilkan sebuah produk. Saat ini di lingkungan kita sendiri bahkan juga pemerintah sedang gencar – gencarnya melakukan pembangunan maka oleh karena itu mungkin dapat membantu memenuhi kebutuhan pada sektor tersebut. Penulis menciptakan Alat Interlocking Brick System. Alat ini dikendalikan melalui sebuah panel kontrol dengan memanfaatkan sistem hidrolik. alat ini dapat berkerja dengan dua mode sistem kerja yaitu sistem kerja manual menggunakan hand valve dan juga sistem kerja dengan menggunakan tombol serta di lengkapi dengan satu tombol emergency yang berguna untuk meng-non aktifkan semua sistem kerja alat serta sebagai pengaman apabila terjadi kecalakaan kerja. Untuk melakukan proses pembuatan batu bata interlocking brick system ini menggunakan mould (cetakan) yang sesuai dengan jenis batu bata tersebut yaitu menggunakan mould interlocking brick system, Untuk melakukan proses pencetakan interlocking brick system penggerakannya menggunakan sistem aktuator hidrolik. Hasil dari alat Interlocking Brick System ini diharapkan dapat mencetak intercking brick system dengan baik.

Abstract

Shaft and roll bending is an element of a machine used for rolling pipes, bending pipes to curved and formed the desired angle. Roll operations often accept the burden that intersect between the pipes and the roll. The load will result in stress and strain. To make roll work safely, the various stresses and strains that occur must be calculated by using numerical simulation software to determine stresses and strains that occur on the shaft and roll bending. The bending of the shaft caused by a given load on the axis is F = 3382.339 N, and the loading on the roll bending that occurs on the surface of the exposed pipes is equal to F = 3361.51 N. Distribution of maximum shear stress that occurs in the shaft mounted roll bending is = 135.3 MPa. The maximum shear stress distribution that occurs in roll bending is = 69.91 MPa. The maximum strain distribution that occurs in roll bending is max = 9.088 x10-3 Mpa, and the maximum strain distributionthat occurs in the shaft is  max = 2.507 x10-3 Mpa. With these results, shaft and roll bending can work safelybecause the voltage that occurs does not exceed the voltage that occurs on the shaft and roll.

Abstract

The development of Hydroulic Regenerative Shock Absorber starts with presenting theories that work, and simulates them with numerical computing software to becompare with conventional shock absorber systems. The generation energy of the regenerative suspension system is only effective for high amplitude. When the amplitude is low, the generation energy will decrease as a result of bidirectional rotation and inertial losses. The greater the generator rotation, the higher current, and power generation. In the HMERSA fluid flow simulation 1 input and single output using the Fluid SIM software. the input given is 3 Hz on the hydraulic cylinder that is on the 4-wheel vehicle. The simulation was done by changing the hydraulic circuit and adding a check valve mechanism so that the rotation of the hydraulic motor becomes unidirectional. In this simulation there is no generator component because in the Fluidsim software does not provide these components in the simulation. The simulation using the Fluidsim software is intended to find out whether the hydraulic circuit that has been designed runs well marked by the rotation of the one-way hydraulic motor rotation. The design design of HMERSA with 1 input 1 output can run well marked from the rotation of the hydraulic motor into one direction when the conditions are expansion or compression. The torque value that occurs during an expansion condition is 1.1 Nm, while for the torque value that occurs when the compression condition is 1.6 Nm. The power generated from the hydraulic motor when the expansion condition is 1.6 Watt. Whereas when the compression condition of the power of the hydraulic motor that can be produced is 4 Watt.
