Abstract

working. Workmanship of austenisation is done through warm-up of specimen at temperature 9000C during one hour clock, then made cool in coolant giving speed of different refrigeration. As coolant is refrigeration of lag in refrigeration stove in air-gap (air), dye oli, and dye water giving speed of highest refrigeration. Attempt result indicate that strength of steel from material early 423,9 MPa, after diaustenisation specimen, the strength increase becoming 474,9 MPa through air cooling, and 560,5 MPa through refrigeration dye water. Media cooler dye water, yield mechanical property is less good, because specimen manjadi is fragible (small elongation 6%). Microstructure observation becomeed militant, phase which formed is ferrite as matrik and pearlite. Increasing of strength of call is caused by item formed by pearlite is higher distribution from at initial material. Specimen with refrigeration dye water, microstructure type which formed becoming change, phase which formed is ferrite of form of needle as matrik and martensite. This microstructure type give metal become brittle. Although the strength is highest (717,3 MPa).

Abstract

Bearing is a prayer one part of the holding machine elements because Important role of bearing namely functions to review rivet a shaft so that the shaft can be spun without experiencing excessive friction. Bearing generally used to review round prop shaft where at occurred many friction. From then that on bearing component materials had made of strong enough for a review allows the shaft well as other machine elements working good and optimal. Research singer aims to review determine mechanical properties of components bearing material with carbon steel high (high carbon steel) SUJ 2 the treated Heat Carbonnitriding with Temperature of 850 ° C, Hardening 830 ° C with cooling oil during a 15 minute shower taxable income next using the water conditioning on hold for 15 minutes bath Tempering 185 ° C and cooled with room temperature for 120 minutes. Testing results chemical composition is known that the basic ingredients of the basic SUJ 2 has a Fe content of 98.23%, C 0.93% and 0.10% Cr content that can be classified as high carbon steel crhoom. Observations showed metaloggrafi the homogeneous microstructure with more Subtle form of austenite grains, martensite and carbides, carbide where the surface surrounding the bearing component. Results  hardnes test components vickers bearing SUJ 2 has a value to keep pace with the heat treatment of non-taxable income 199.8 HV experience heat treatment 1 process being 910 HV, on process heat treatment 2 being 810 HV.

Abstract

Wheels are one of the main components in a vehicle. Without wheels of vehicles will not be to function. The damage that occurs in aluminium alloy wheels for the outbreak spoke mostly occur due to a force and tension that occurs exceeds the maximum allowable voltage. With these considerations it is necessary to redesign using 3D software and simulated using finite element method. After simulated, part produce with low pressure casting and machining. Sample part test with several testing as single part such as : life test, drum test, 13° impact test. After that sample part test as running test such as : curb stone evaluation and rectangle evaluation. The results of sample testing parts such as life test, the drum test, 13 ° impact test and running test in the form of curb stone rectangle evaluation and evaluation did not reveal any cracks on the sample part. Nut torque results of sample testing parts such as curb stone evaluation have smaller in 70 N.m, with allowed limit 61,6 N.m until 88 N.m. And nut torque results of sample testing parts such as rectangle evaluation have smaller in 76 N.m, with allowed limit 61,6 N.m until 88 N.m

Abstract

Cleanroom in the pharmaceutical industry is needed to eliminate a wide range of contamination, due to the room around the building materials, machinery equipment production, human and others generate millions of particles that can interfere with the quality of manufactured drugs. Cleanroom in the pharmaceutical industry is based on the ISO 14644-1 standard that is in a class of E (100.000), which can be interpreted very clean conditioned room to awake from particles and microbial contamination. The number of particles in the E (100.000) class at the size of 0,5 µm limited number of 3520000 particles/m3 were obtained from the results of the design of 446771,3769 particles/m3, for a particle size of 5 µm particle number 29000 particles/m3 is obtained by 47760,7813 partikel /m3. Raw material weighing room temperature in the desain room 21 ºC and 40% RH, and the outside temperature is 32,72 ºC and 72,77% RH. The results obtained design cooling load is 17329,077 Watt, with velocity distribution of air in the airway of 0,118 m/s in air requirement of 99,615 l/s, so that the requirements for class E (100.000) according to ISO 14644-1 to the mixed flow of air velocity.

Abstract

This analisys who does are to point off base on motorcycle community to able learning education such as purpose and quality of break kanvas with standardization even chossing of material pad kanvas who does no failed of chossing as performance capability in  deserasy of speed. For knowing for that, firtable we must to analyzing of performance and compared. In this section are used two of sample with deference kind of material, such as non asbestos (semi metallic). For in this case we take a tree experiment, like measuring analyse, threadbare and scrape. Of the end analyse that could knowing are using material non asbestos (semi metallic) are excelellen better than asbestos kanvas as orientation SNI number 09-9134-1987. As you know share, using far away way are suitable in non asbestos and recomanded.
