TomyadAuto® Vortex Concept

TomyadAuto Vortex is a concept car in MPV body style which is designed by SolidWorks and rendered by PhotoWorks with global illumination. The car body is created using surfacing and thicken tools.

Regression using Wavelet Neural Network

This VB.NET source code uses Wavelet Neural Network to approximate single-variable functions. Training data should be inserted to the Access database for supervised learning. User is able to select number of processing neurons, learning rate and learning iterations. The project has the feature to plot approximated functions.

Shaft Designing using MATLAB

A shaft is a rotating member, usually of circular cross section, used to transmit power or motion. It provides the axis of rotation, or oscillation, of elements such as gears, pulleys, flywheels, cranks, sprockets, and the like [Shigley’s Mechanical Engineering Design]. Main goal of a mechanical engineering for designing a shaft is to determine shaft average diameter.

In ShaftDesigning source code, user should determine design factor, stress concentration factors, Marin factors, maximum bending momentum, maximum torsion, shaft material properties and initial value for shaft diameter on the . Then the source will calculate a good approximation for shaft average diameter by fixed point method. Combination of Von Mises yield criterion and Soderberg criterion are used for dynamic designing.

ShaftSolver source code is an additional tool for calculating bending momentum and torsion on the shaft. The code also solves supports forces and plots total momentum diagram based on elements used on the shaft.

MATLAB Spring Designing Source Code

The MATLAB source code is for designing springs under static pressure load. User choose spring wire material, wire diameter range and load properties. And then by running the code, spring diameter, spring index, effective turns, critical length and pitch will be determined. The code also supports spreadsheet output.
