Safety at work should be a priority in any operation, but in emergencies, quick and assertive decision-making can be the difference between life and death. To increase operator safety during activities carried out at height, it is essential to determine the maximum wind speed for safe operation. This is a classic example of an operation using rappelling. In these conditions, the operator faces high-speed winds, which can cause oscillations during work and can result in collisions with other equipment or objects. But how can you anticipate and plan responses to these events? This is where CAE simulation makes all the difference.
CAE Simulation
The acronym CAE (Computer-Aided Engineering) refers to Computer-Aided Engineering, a technology that uses software to simulate and analyze engineering projects. This tool allows you to predict the behavior of a product before its physical construction, assisting in the development and improvement of projects.
CAE simulation is applied in several areas, including structural, fluid, thermal and electromagnetic analysis. The best-known and most widely used techniques are Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).
The benefits of CAE simulation for companies are:
Greater efficiency, reliability and quality
Cost reduction
Reduced developer time in product development
Elimination or reduction in the number of test prototypes to be built
Increased competitiveness
CAE simulation allows for the digital recreation of several scenarios, for example, by analyzing factors such as fall conditions, interaction with the environment, performance of safety equipment and emergency evacuation strategies. With this information, it is possible to improve equipment, enhance protocols and develop more effective training to increase the safety of workers and rescue teams.
The Importance of Emergency Planning
Emergencies such as falls, leaks or fires can occur even with rigorous preventive measures. The difference lies in how well the team and systems are prepared to deal with these situations. CAE simulation transforms the unpredictable into something controllable, allowing:
Faster responses: Equipping teams with elaborate information and ready action plans.
Damage reduction: Minimizing impacts on the worker and the operation.
Tragedy prevention: Developing strategies to prevent similar situations from occurring again.
Simulation
The operator, weighing 90 kg, is suspended by a rope, simulating a rappel down a 50-meter tower. The analysis considers the acting forces, such as weight, wind force and turbulent interaction and the tension on the rope. The simulation allows for the inclusion of an air speed curve in relation to height, making the assessment of air flow more accurate, considering turbulence and interaction with the environment.
Including the air speed curve in the simulation allows us to assess how wind currents influence the operator's oscillation during rappelling. The intensity and direction of the wind affect the operator's movement, impacting balance and stability. With this analysis, it is possible to predict these effects, helping to understand external forces and their impact on the safety and performance of the operation. In addition, the data obtained allows us to optimize the planning of activities at height and select the most appropriate equipment to reduce risks.
During the simulation, it was possible to determine the force applied to the rope, considering the environmental conditions and the characteristics of the rappelling operation. Factors such as wind speed and sudden movements directly influenced this force.
In scenarios with strong winds, with a speed of 15 m/s, the force on the rope reached a peak of 3000 N, which can reach the breaking limit of the rope. This result highlights the importance of evaluating environmental and operational conditions to ensure safety, in addition to the need to carefully choose the materials and equipment used in risky activities.
Commitment to life
The application of numerical simulations goes beyond innovation; it is a demonstration of commitment to the safety and well-being of workers. In times of emergency, where decisions need to be made in seconds, having the confidence that every detail has been analyzed and planned can save lives.
