Cost Effective Automatic Garage Door Mechanism With Variable Speed

The aim of our project is to provide safety as well as security to people from the largest electromechanical objects which are available at home. An automatic garage door mechanism was selected as a subject of our research as it is the complex electro-chemical object at home. As technology increases day by day every households installs this automatic garage door mechanism. The major problem with the conventional garage door system was child entrapment and people are in wheelchair are also affected by the conventional garage door mechanism. We are planning to eliminate the problems which are available in the conventional garage door mechanism by providing some extra safety and security features to our automatic garage door mechanism.an automatic garage door mechanism is the combination of mechanical and electrical system in which mechanical system guides the system as well as direct the shutter movement While, electrical system is used to provide energy to mechanical part. Sectional overhead doors have become the standard door type for garages. Our motive behind this study is to increase the safety and security of the automatic garage doors as well as make it to operatable at variable speed. Safety of the equipment is going to be increased by an area presence sensor which will reduce the child entrapment cases. Only authorized people can access the garage, that will increase the security and use of the VFD-variable frequency drive will make the garage door operatable at owner desired working speed. These shutters can be used for home applications as well as industrial applications.

Stiffness Optimization of Control Unit of Vehicle Using Vibration Technique

All modern automotive engines are controlled by an ECU. Engine efficiency, combustion, and emission characteristics are all affected by ECU tuning or tune-up. The electrical system in automobiles has evolved over time, and it now incorporates automatic machine control of automotive mechanics. In the beginning, a car’s electrical system consisted solely of primitive wiring technologies for supplying power to other parts of the vehicle. Engine management design specifications for the electronic control unit (ECU). Electronic systems are an unavoidable part of Engine management due to legislation requiring lower pollution, as well as the need for improved efficiency, fuel economy, and continuous diagnosis. The ECU of a TOYOTA Soluna car was used in this project for research and experimentation. ANSYS 19 software will be used to perform a modal and harmonic analysis of the current control unit. After that, different stiffener patterns will be added to improve the vibration characteristics of the ECU housing. We will finalize the stiffener pattern based on the FEA results. The FFT analyzer and the impact hammer test will be used to conduct experimental vibration testing.
