| Abstract: |
We propose a technique for conducting a comparative analysis of locomotive headlight designs with different light sources. The technique involves a number of stages of numerical analysis for modeling the impact of vibration-related deformations characteristic of the locomotive in motion on the reliability and photometric characteristics of the headlight. The main stages of this analysis are: creating a 3D model of the analyzed lighting device; determining the natural frequencies of the device based on the use of ANSYS Workbench program; modeling deformations of the device at its natural frequencies; analysis of the contribution of deformations of components in the largest deformation of the entire device; based on the calculation of the ray tracing the analysis of functioning the lighting device in conditions of the greatest strain. Based on the technique proposed, we investigated the different designs of the locomotive headlight: 1) with bulb as light source; 2) with LEDs as light source; 3) with LEDs mounted on a perforated substrate; 4) with LEDs on the perforated substrate reinforced with ribs. Thus, we offer a solution to the problem of joint analysis of searchlight vibration loads and quality of directivity diagram formed by the headlight. A key element of the analysis is the use of dynamic visualization of the vibration oscillations for the headlight and of formed (under a maximum distortion of the searchlight structure) light beam. |
