Railway construction projector with led light source

Obtained in the ANSYS software environment the natural frequencies of the two constructions of the modernized railway floodlight. In the first case, in serial floodlight incandescent lamp was replaced by a group of LEDs mounted on a solid cylindrical substrate. In the second design spotlight substrate carrying the led light source was equipped with radial ribs and concentric shells stiffness. The analysis of the nature of the deformation of the substrate when the vibrations at the natural frequencies has established a number of design solutions that improve the vibration resistance of a spotlight. Model spotlight, it was found that the natural frequencies of a spotlight with a solid substrate owns virtually the entire range of railway vibrations. The eigenfrequencies of the substrate, provided with holes, ribs, and sides of stiffness, belong to the low frequencies of vibration interval train locomotive. Based on the developed method of analysis of deformation and natural frequencies of the surface carrying the LEDs is proposed and studied the design of a vibration-proof floodlight.
