“…These tests usually concern the engine and drivetrain, steering, frame, cab, seats, suspension, hydraulics, and controls. However, the performance of such tests requires the establishment of test stand control signals (obtained by the compilation of the recorded road load data acquisition-RLDA) [5, [15][16][17] and the satisfaction of the test stand requirements, which limit the possibility of testing vehicles with 6 × 6 or larger chassis and over 6000 kg GVW [11]. Moreover, such stands are very expensive; for this reason, they are used by the largest vehicle manufacturers [18].…”

“…Long-distance road tests of a vehicle are time-consuming and costly if only a single vehicle is available. Therefore, ways to speed up tests performed under contract research conditions, e.g., by increasing the driving speed during the tests, choosing test road sections that generate higher loads than those generated under the conditions of normal vehicle operation, and not carrying out road tests where the level of loads does not significantly limit the durability of the vehicle component being tested [15,19]. Therefore, it becomes particularly important to establish reference test road sections and running speeds for mileage tests under contract research conditions in order to establish the correlation between vehicle driving conditions (load, speed, road type) and the Remaining Useful Life (RUL) of the selected key vehicle components [20].…”

Before being introduced into the maintenance system, each vehicle must undergo a series of tests, including durability tests. Computer models and whole vehicles on test stands can be used to identify vehicle performance parameters, which requires access to special software and test stands. However, due to the size of the vehicle or access to test stands, experimental tests must often be carried out on proving grounds; while generating the most complete set of loads, this is much more time-consuming. Therefore, methods are sought to indicate whether testing at the proving ground can be accelerated, for example, by increasing the speed of driving or using test road sections that generate more severe loads. This paper presents a method for evaluating the suitability of selected test road sections for durability tests of a special high-mobility wheeled vehicle. The method is based on the Basquin model, which consider the fatigue strength of materials, and rainflow load cycle counting method combined with the P-M damage summation method. Evaluation of test road selection was supplemented with analysis of travel speed distributions determined using the Beta statistic distribution. The presented model was used to evaluate the ability to accelerate a mileage test of an 8 × 8 vehicle. While certain data mentioned in the article remain classified and are not able to be presented in full, the author has attempted to provide a comprehensive background of the analyses conducted and the data used to illustrate them.

Ensuring demanded service life of a vehicle is a relevant engineering problem. Currently, resolving this problem is heavily complicated. Modern tendencies of automotive industry assume shortened development cycle for new vehicles and sustaining wide lineup of cars for manufacturers. Performing long-term durability testing of vehicle subsystems is becoming limited. Meanwhile, methods of laboratory testing, which provide higher acceleration degree of damage accumulation in comparison with testing on proving ground, are progressing. Virtual simulation methods, which allow analyzing and optimizing a new design at early development stages, are becoming widespread as well. Modern durability analysis methods, based on laboratory testing and virtual analysis, and load cycle generation methods, used for testing and simulations, are considered. Some points are noted, such as an extensive use of described methods of durability research among foreign car manufacturers, and the relevance of developing this kind of durability evaluation methodology for the Russian automotive industry.
