A study was made of the operational reliability of the frame of a truck, taking into account the optimization of the frequency of maintenance. The KamAZ-4308 vehicle was chosen as a technical object, as it is one of the best-selling and exported on the Russian market among heavy trucks with a gross weight of 14 to 40 tons in 2021. A technique has been developed to find the optimal value of the value of the frequency of maintenance of the basic parts of the car, taking into account operational reliability, as well as minimizing the initial data to obtain numerical results, which will reduce the time and laboriousness of the experiment and reduce the economic costs of its organization and implementation. When modeling the resource distribution, options were considered for strengthening the frame structure by changing the steel grade, wall thickness, cross-sectional area, and others. The empirical and approximating functions of the general population of the finite volume of the resource Tr of the KamAZ-4308 car frame are obtained.
