The article presents the results of assessing the possibility of using simulation modeling to predict the ferroresonant process in electrical networks. A mathematical model of a three-phase power transformer in the form of a system of differential equations is considered. The MatLab software package was chosen as the modeling environment. In the conclusion of the work, the results of simulation were analyzed and the correspondingconclusions were drawn.

Abstract A set of routines is developed using the MATLAB software package to aid students in learning methods of frequency response analysis. Routines are menu driven which would require minimum knowledge of MATLAB commands. A rapid sketch of asymptotic Bode plots is emphasized which is the basis for the lead, lag, and lead-lag compensator design techniques in the first control course taught at Western New England College.

The paper presents a method for estimating the efficiency of the manual nesting process. By using the graphic file generated during the nesting process and using image processing techniques, the method allows the user to calculate the percentage of material used for manufacturing the parts. The method combines a manual approach - the user has to select some specific points on the graphic file with the mouse, with some image processing algorithms form Matlab software package.

Gear Rattle

This paper describes a model for torsional vibration of automotive manual transmissions and its subsequent analysis. The model is developed for the purpose of analysis and prediction of gear rattles. Efforts have been made to include as many components of power train as possible and to study the rattle responses of all the speeds. Elements of the model include engine, clutch, flywheel, laden and unladen gears, and shafts. Numerical methods available in MATLAB for solving the ordinary differential equations are employed for the dynamic analysis. Results are presented to show the effectiveness of the modelling and analysis scheme. A software package has also been developed to build and analyse any power train model. The package was used to analyse the Daimler-Chrysler T350 transmission and the results are presented in the paper. It is shown that the gear rattle may exhibit three major modes of double-sided, single-sided or irregular impacts. A rattle index has been used to compare the rattle levels produced by different gear pairs. This could be very useful for the purpose of tuning the clutch for the best rattle noise reduction.
