Abstract

Analysis of structural strength of mechanical systems on digital x-ray devices. This research is very important to know the strength and quality of the structure of mechanical system of digital x-ray plane. To research analysis strength structure system mechanical calculation methods were used counting stress, bending stress; the safety factor a tool, and calculate deflection occurring in structure.The result of his research or: the bending stress at order holders catcher of = 7,07 N/mm2, while the bending stress is equal to = 141,9 N/mm2. The bending stress on the tube holder is as big as = 7,8 N/mm2, while the bending stress is equal to= 141,9 N/mm2. Stress von mises in order arms part burden a counterweight of = 19,44 N/mm2, while the value of the safety factor is n = 11,05. Stress von mises in order to arms a part of encumbering tube = 18,41 N/mm2, while the value of the safety factor is n = 11,67. Bending stress happened to column of order = 22,60 N/mm2, while the bending stress is equal to = 141,9 N/mm2. The ball screw move of the operation Fbm = 777,9N. Bending stress occurred on the basis of order = 21,43 N/mm2, while the bending stress is equal to = 141,9 N/mm2. Based on the data has obtained, then structure mechanical system plane digital sinar-x expressed safe and strength.Analysis of structural strength of mechanical systems on digital x-ray devices.

Abstract

Steel rope is one of the most important parts of the aircraft's systems lifter. Strength steel cord vary, depending on the terms of usage and requirements of a building. Construction steel rope which is typical for elevator consists of 8-spun wound together, the direction to the left or right with the middle core. Each spun steel strap consists of 19 wires is 9.9.1, which means outside the wire 9, 9 inside and one in the center. Sectional area of the steel rope (F152) based on the tensile stress to a steel rope (S) is 1.9 cm. Tensile stress occurs in the steel cord is equal to (S) = 1894 kg. While the tensile stress is permitted (Smax) = 2800 kg. Actual breaking strength steel strap (P) by the safety factor with the types of mechanisms and operating conditions (K) is (P) = 10417 kg. The lifetime of steel ropes obtained from this analysis is 120 months or 10 years in normal use 8 hours per day. Steel rope used types : 8 x 19 = 152 + 1 Fiber Core specification: diameter steel rope (d): 10 mm, weight of the rope (W): 1.15 kg / m, the burden of broken steel rope (Pb): 15,400 kg, rope fracture stress (σb): 140-159 kg / mm². Due to the tensile stress (ST) = 1894 kg less than the tensile stress that is authorized (Smax) = 2800 kg, it can be concluded that the steel straps secure against tensile loads that occur
