Abstract

There are two important matters in the suspension system that must be concern, there are comfortable and stabilityof vehicle that provide or supported by the whole suspension system. Whereas passive suspension system design only concern with comfortable or stability of vehicle with pros and cons from that aspect respectively.In the active design, the two aspect can be achieved with minimize cons respectively. However active suspension in the application iso complex and high cost. Many research looking for the solution between two systems, one of them was using dynamic vibration absorber (DVA) and semi-active suspension. ISE, IAE, and ITAE are used for performance index to achieved optimum control gain from trial error tuning with 0,001 – 10 range. The result shows that Semi-active suspension system (SSSA) with gain = 3, can  achievedmaximumovershoot reduction 28.29%, for gain = 4 maximum overshoot reduction 24.32%, and  forgain = 7maximum overshoot reduction 18.61% compared to passive suspensionin step mode.

Abstract

Aluminum alloy Al-7Si is suitable for material of wheel rim of racing car, however its mechanical properties has not met the required standard JIS H5202, so it needs to be improved. Improving mechanical properties can be done by adding element alloys and heat treatment. This present research in concerning with Al-TiB enhancement into the Al-7Si aluminum alloy to increase the Titanium content of 0.13%w to 0.14%w, 0.15%w, 0.16%w until 0.21%w. Therefore, these samples were treated by heat treatment T5. The Addition of Al-TiB caused the micro structure of the grain become smaller and softer, and also increases the mechanical properties (UTS and Hardness), but it has not met standard JIS H5202 yet. After heat treatment T5, the form of grain change from ellipse to circular, the mechanical properties improve significantly and beyond the standard JIS H5202.

Abstract

Hardenability of steels is an important way to determine heat treatment and material properties that produce component products. Jominy test is one of the method to know hardenability of steels. The Jominy ASTM A255 in used as a method for carriying out and this reseach. Parameter such as austenite temperature, holding time, cooling rate and then the results is dedicated by the prediction result, with Non Linear Numerical Equation Method. Based on test, it’s known, increasing austenite temperature, longer holding time and high cooling rate, will increase hardenability of steels. The different between the results and the prediction result done by Sonh Yue-Peng[15], Matja equation[14] and Zehtab equation[10], about 5 % -10 %. The data obtained from this experiment can be used to determine the appropriated heat treatment in order to get the desired mechanical properties, as well as to avoid distortion.
