TRAVELLING RESISTANCE DETERMINATION OF A BRIDGE CRANE BY STATISTICAL METHODS

The article presents a new method for solving the scientific and practical task of automating the calculation of the weight of general-purpose overhead cranes. The numerical data on the weight of existing cranes are provided in tables and structured according to load capacity and span. Hypotheses of mathematical statistics were applied, which allowed the results to be distributed according to the normal law under the assumption of equal accuracy of the obtained data. Based on these assumptions, the method of least squares was used to construct a two-variable function that establishes the relationship between the crane's weight, span, and load capacity by combining these parameters. A formula was derived that enables the weight of cranes to be calculated programmatically. The advantages of the proposed method are substantiated in the article.
