Research of dynamic load capacity of tipper car using mathematical model method

Methods for restoring coal flowability are considered and some of them are accentuated. The results of the analysis of load-carrying structures of low-sided cars when exposed to thermal methods of restoring coal flowability are presented. The study was conducted using the industrial FEM software complex. The assessment was carried out for two typical low-sided car structures - with a solid floor and hatches on the frame. Studies have shown that thermal loading significantly affects the low-sided car supporting structures and should be taken into consideration when designing cars of enhanced performance properties. The main low-sided car design feature, considered in the paper, is the presence or absence of load-bearing flooring with longitudinal reinforcements. The presence of a carrier floor in the body reduces the load level of the lower trim in its average section. When comparing the loading of both types of bodies, it can be seen that the backward body of the low-sided car perceives loads, both power and thermal, better. According to the results of the calculations, it is possible to say about the priority of the use of infrared irradiation, as a scheme for restoring the flowability by the criterion of minimizing the thermal loading of the supporting systems of the low-sided cars.

A method of reinforcing conical reinforced concrete struts by external reinforcement with composite materials is considered. The calculation of reinforced concrete struts according to the limiting states of the first group, reinforced with composite materials in accordance with the requirements of SP 63.13330.2012 and SP 164.1325800.2014. Based on the calculation, a comparative analysis of the characteristics of polymer composite materials presented on the domestic market is carried out, rational schemes of external reinforcement of conical reinforced concrete racks are proposed, used as an AMC for installing antenna-feeder equipment for cellular communication. The results of the analysis can be used for a rational choice of polymer composite materials and reinforcement schemes for conical reinforced concrete struts.
