Abstract

Electric road sweepers often face damage to wire broom components due to manual operation errors, particularly when navigating obstacles like speed bumps. To mitigate this, an automatic arm lifting system using proximity sensors was developed to enhance efficiency and extend broom lifespan. This study focused on designing the wiring, determining optimal sensor detection distances, and assessing sensor angle inclinations for an electric road sweeper prototype. Functional testing determined that Sensor A should be placed 60 cm from the wire broom with a tilt angle of 42.2Ëš, a distance of 2936 mm to the ground, and 2800 mm to the object for lifting commands. For Sensor B, the lowering command requires a tilt angle of 49.4Ëš, a distance of 20 cm from the wire broom, 2692 mm to the ground, and 2200 mm to the object. These settings ensure the system effectively lifts the sweeper arm over obstacles, enhancing both efficiency and durability. The findings demonstrate the potential for advanced sensor technology to improve urban cleaning equipment and support sustainable city maintenance practices.

Abstract

Heat transfer is a process that underlines many engineering applications. Temperature distribution and heat flux of a part as an effect of heat load can be analyzed for technical and economic justification. Computation has been easier with the aid of computational software based on numerical methods. The numerical method is about approximation; therefore, validation is necessary to verify the accuracy. A comparison of numerical and analytical methods on a plane wall thermal analysis had confirmed that the result from ANSYS fluent satisfies the computation. The results were strengthened by the negligible error when comparing the analytical and numerical methods. An extended study was performed to further investigate the significance of numerical and physical parameters on the result. The numerical parameter does not seem to have a significant effect, yet the physical parameters do. The study can be employed to predict the generated heat flux from various parameters under predefined operating conditions.
