Abstract

Load on the transport vehicle is one of the most important parameters, to be taken into account in the process of its operation, as it influences the controllability, stability, operation characteristics and safety of the transport vehicle. Determination of the regressive interdependences between the load and the intensity of the weight wear of the transport vehicle tires in the process of transportation is the relevant scientific-engineering problem. The objective of the research is the construction by means of regression analysis the regressive interdependences between the load and intensity of the weight wear of the transport vehicle tires during transportation which can be used for the improvement of the safety level and reduction of the risks for the workers, involved in the process of loads transportation. In the process of investigation, method of regressive analysis of the results of single-factor experiments and other paired dependences with the selection of the rational type of function among the most widely spread variants by the criterion of maximum value of the correlation coefficient was used. Regressions were carried out on the base of the linearized transformations. Enabling to reduce the non-linear dependence to linear one. Determination of the coefficients of the regression equations was performed, applying the method of the least squares by means of the developed computer program "RegAnaliz", protected by the Сertificate of the state registration of the rights to the copyright object. Adequate regression interdependences between the loads and technical state of the transport vehicle in the process of transportation have been obtained, they can be used for the improvement of the security level and risks reduction for the workers, involved in the process of cargoes transportation. Graphic interdependences between the loads and the intensity of the weight wear of the transport vehicles tires have been constructed, they enable to illustrate these dependences and show the sufficient convergence of the theoretical results with actual. It is established that with the increase of the longitudinal and transversal forces in the area of the tires contact with the road surface the intensity of the tires wear increases by power dependences. In this case the increase of the intensity of weight wear of the tires as a result of transversal force increase is more intensive than as a result of longitudinal force increase.
