Improvement of the Method of Wear Control of Motor Vehicles and Their Main Units

Abstract

In the Provisions [1] specific norms of spare parts consumption by mileage intervals before overhaul are given,which created the prerequisites for the management of vehicle wear, which requires a machine-by-machine accounting of spare parts consumption. Analysis of experience in applying these standards revealed their effectiveness from the standpoint of wear management of road transport rolling stock. In this regard, there is a task to further improve the method of rationing and extend it to the main units. In this paper, we propose a method of controlling the wear and tear of the main units on the example of the motor vehicle engine, which provides standards for the cost of current repairs – spare parts and labor costs, as well as the cost of damage due to wear and tear. Based on the information revealed, the average rate of iron in the engine oil for each of the engines under control is calculated, and then determined the average rate of iron in the engine oil, which allowed to determine the dependence of cylinder liner wear on the operating time, oil burnout on wear. As a result of processing the initial information of the under-control vehicle operation, the numerical values of the parameters of the curves of dependences of the cost of current repairs on the operating time, and according to the results of spectral analysis of engine oil and accounting for its refill – engine cylinder wear on the operating time and the cost of compensation for losses from wear were determined
