Abstract

This study explores the potential of using sound signals to visualize corrosion within pipes. Early detection of pipe damage is crucial in preventing leaks and larger losses, especially in industries that rely on pipes for fluid distribution. Sound-based methods have advantages in detecting damage in hard-to-reach areas without direct contact with the pipe's surface. This study demonstrates that microphones mounted on the pipe surface can capture variations in sound signal characteristics related to corrosion conditions. To simulate corrosion in pipes, a layer of plasticine was applied to a specific area of the pipe's inner surface, creating a model of corrosion damage. The test results show that microphone positions aligned with the corroded area produce higher signal coefficients compared to non-corroded areas. With further processing, these signal data have the potential to be visualized as 3D images, providing a more detailed representation of the internal conditions of the pipe.

Abstract

Position, speed, and acceleration analysis are all included in kinematic analysis. Vectors of location, velocity, and acceleration can be expressed analytically in the form of complex numbers using the Newton Rhapson Iteration Method. The location vector of the point to be investigated must be found first, and then the acceleration and velocity vectors must be found by differentiating against time. This study analyzes the relationship between the θ1 value and the θ2, θ3, θ4, θ5, and x2 values in a drag-link mechanism. The Newton-Raphson iteration method is employed for kinematic analysis to solve nonlinear equations. In this research, the analysis results indicate a correlation between the θ1 value and the θ2, θ3, θ4, θ5, and x2 values. As θ1 increases, the θ2, θ3, θ4, and θ5 values also proportionally increase. The x2 value is also influenced by changes in θ1. This study combines the Newton-Raphson iteration method with graphical analysis using CAD software. The conclusion of this research highlights a significant relationship between the θ1 value and the θ2, θ3, θ4, θ5, and x2 values in the drag-link mechanism. The analysis provides valuable insights for modeling, designing, or controlling systems involving these variables.
