Establishing the peculiarities of tire wear of garbage trucks during the transportation of municipal solid waste

Abstract

The article is dedicated to the establishment of peculiarities of tire wear of garbage trucks during the transportation of solid waste. Using the planning of the first-order experiment with the first-order interaction effects using the Box-Wilson method, adequate dependencies of wear of garbage truck tires on the front and rear axles due to the transported mass of municipal solid waste and the mileage of the garbage truck were determined. It was established that, according to the Student’s criterion, among the investigated factors of influence, the wear of garbage truck tires on both the front and rear axles is most affected by the transported mass of municipal solid waste, and the least – by the mileage of the garbage truck. The response surfaces of the objective functions – tire wear of the garbage truck on the front and rear axles and their two-dimensional sections in the planes of the impact parameters are shown, which allow to visually illustrate the indicated dependences of the objective function data on individual impact parameters. The dependencies of the number of routes of the garbage truck to the maximum allowable tire wear on the front and rear axles were obtained. The response surfaces of the target functions – the number of routes of the garbage truck to the maximum permissible wear of the tires on the front and rear axles and its two-dimensional sections in the planes of the influence parameters, which allow to visually illustrate the specified dependencies, are obtained. The expediency of conducting further research on the influence of speed, unevenness of the road surface, weather conditions and other factors on the wear of garbage truck tires has been revealed.
