Abstract

The purpose of this study was to analyze the stress, displacement, and factor of safety that occurred in the valblock safety device. With the maximum load that occurs at the knuckle is 7473 N. Testing is done using Solidworks simulation software. The material used is AISI 1045 with allowable stress of 450 MPa. The results of the analysis that came out of the simulation were the maximum stress values, displacement, and the factor of safety. The maximum stress results in static conditions that the tool is only able to withstand loads up to 7000 N with a value of 3,540 , and does not exceed the maximum allowable stress limit of the tool, which is 5,300 . The result of the loading is a change in the shape of the stem, namely displacement or deflection. The results obtained from the deflection of 1.3 mm. For the results of the factor of safety, the tool is worth 1.5 at a load of 7000 N so that the valblock safety device is safe to use up to 7000 N loading.

Abstract

Composite material is a type of new, engineered material consisting of two or more materials where the properties of each material differ from one another both in chemical and physical properties and remain separate in the final material. Composite materials have many advantages, one of which is lighter weight and corrosion resistance. In this study, composites made from glass fiber were carried out with variations in the arrangement of laminates, in order to select the material which was then applied to the manufacture of the inspection lorry body. Composites were made using the hand lay-up method. Tensile test specimens made according to ASTM D-638. The results of the tensile test show that the highest tensile strength of glass fiber composite material for the inspection lorry body is 5.45 MPa and the lowest tensile strength is 4.62 MPa.

Abstract

Locomotive CC 206 is the newest locomotive owned by PT Kereta Api Indonesia. Inside the CC 206 locomotive is equipped with a sophisticated smart display that can monitor all size parameters and damage to the locomotive itself. One of the capabilities of the CC 206 locomotive is the pop test. Pop test is the ability of the CC 206 locomotive to test the performance of each cylinder of the diesel engine. Based on the pop test results, there are various disturbances that often occur during maintenance of the CC 206 locomotive diesel engine.The purpose of this analysis is to analyze the pop test results as a reliability parameter on the CC 206 locomotive diesel engine, to analyze the factors causing the disturbance in the pop test results and analyze the effect of the failure of the pop test results on performance. Based on the results of the pop test, it was found that one of the cylinders was abnormal because the injector was under pressure, the injector spring was damaged and there was a clogged nozzle.

Abstract

Abstract The fastener is one of the most important components in the railway infrastructure that must be inspected and maintained. Installing and removing fasteners nowadays is still using manual tools like hammers and panpullers which take a long time of 12 seconds and can damage the bearings due to the rebound of the tool. And the current tool is a hydraulic pump-based e-clip fastener installation and removal tool that takes 22 seconds to remove the fastener. Therefore, a device is needed to minimize the damage on the bearing so that its use is more effective and its utility is easy because it uses a control switch that is connected to the battery and then connected to an electric jack. This tool is targeted to be able to release the fastening in a period of under 10 seconds.The process of making an electric jack-based e-clip fastener assisting tool can be carried out in several stages, each of which is the design process, the upper frame manufacturing process, the lower frame manufacturing process, the tool pusher frame manufacturing process, the tool balancer frame manufacturing process, and the completion process. The finishing process of the tool manufacturing.The function testing of the electric jack-based e-clip fastener installation and removal assisting tool at Indonesian Railways Company, Rail road unit, Madiun for road and bridge maintenance. Function testing is done twice with two different operators. The results of the tool function test, the tool can perform the process of releasing one fastener for 5 seconds and can speed up the fastening maintenance process at Indonesian Railways Company, Rail road unit, Madiun.
