Description
Summary:Subject: Fastening of cargo on the car. Topic: Calculation of load shift, elongation and forces in elastic elements of fasteners. Purpose: Describe the parameters of the load and the physical and geometric parameters of the load fastening; give the results of the calculation of the longitudinal forces perceived by the elements of the load fastening; describe the sequence of the calculation of forces in the elastic elements of the fastening according to the recommended formulas. Research methods: The article uses the basic law of dynamics in relative motion for the non-ideal connection known from theoretical mechanics. Main results: The results of the calculation of the longitudinal forces perceived by the load fastening elements, which allowed determining the load shifts along the car, elongation and forces in the flexible fastening elements are presented. Main application of the results: Example calculation contributes to the practical application of a new method of calculating the elements of fastening on the car in the development of schemes of placement and fastening of goods of arbitrary geometry. Conclusions: The results of calculations revealed that the accepted value of the coefficient of longitudinal dynamics of the car corresponds to the shunting collision of the car on the hump yard in the marshalling yards. In this case, additional means of fastening, such as fasteners (nails), are used to ensure the safety of transportation, the safety of the transported cargo and parts of the rolling stock. At the same time, if the shape of the cargo and the useful area of the car allows, you can increase the number of fasteners, otherwise - the number of elastic fastening elements, and sometimes perform both.
