Stiffness Optimization of Control Unit of Vehicle Using Vibration Technique

Suraj Sadaphale, C. S. Wagle, K. K. Dhande

Abstract


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.


Keywords
