Summary:This study aims to analyze the sensors used in an airbag system for automotive applications using LS-DYNA software. Airbag systems are essential safety features in modern vehicles that are designed to protect passengers from injuries during a collision. To ensure the airbag system's effectiveness in protecting passengers, it is crucial to analyze the sensors' behavior during the impact thoroughly. LS-DYNA is a versatile finite element analysis software that can simulate various physical systems, including sensors used in airbag systems. The study focuses on the analysis of different sensors, including accelerometers, pressure sensors, strain gauges, optical sensors, temperature sensors, and infrared sensors. The finite element analysis is conducted to evaluate the sensors' impact on the airbag system's performance, including the deployment time, speed, and force required for maximum occupant protection. The simulation results provide valuable insights into the behavior of each sensor during an impact and their contribution to the airbag system's effectiveness in protecting the passengers. The study provides insights into the optimization of airbag design by analyzing the sensor placement, deployment timing, and force required for maximum occupant protection. The results of the analysis demonstrate that the sensors used in the airbag system are highly effective in detecting the impact and deploying the airbag in time to protect the passengers from injuries. The findings of this study can help improve the safety of airbag systems and contribute to the overall safety of modern vehicles.
