RESEARCH OF THE DETAILS HOLES CENTER-FINDERS ACCURACY BY METHOD OF MATHEMATICAL MODELING
This article is devoted to the development of mathematical model components holes center-finders, which based on the dimension chains and computational mathematics. It’s shown that the tolerance grade calculated in case of the direct task with the given tolerances can be expanded. Methodology for precision estimate of center-finders construction, allows to analyze different types of center-finders, to reveal the links, which are influences accuracy the most and to optimize construction. It was applied for estimate of the accuracy of center-finders standard construction with the given tolerances for a deviation from coaxiality that equal to 0.05 mm (turbine K-300-240) and 0,1 mm (the diesel engine 10D100). In case of the calculating a dimensional chain with the direct task, values were received: 5 accuracy class for the first case, and 6 for the second. For checking results, in case of the reverse task, the computer program calculating closing link according to the Monte-Carlo’s method with the distribution according to Gauss was created. Mean values of deviations on one support made 0,034 mm and 0,051 mm respectively. Aggregate value of a deviation of construction could be define by cross coupling of all supports at each other.
