Abstract

Introduction (problem statement and relevance). The given paper justifies the relevance and describes the process of creating a roller bench for motorcycle and power product fatigue endurance testing. The purpose of the study is to create a roller bench for motorcycle and power product load-bearing structure fatigue strength testing; to develop individual components of the test bench; to analyze the recorded signals during mode metering and during the process of single roughnesses initialization; to test a solo motorcycle on the test bench.

Methodology and research methods. When designing the test bench, Russian and foreign test procedures for motorcycles and automobiles were studied, as well as different patents, articles and papers.

Scientific novelty and results. In order to determine the main parameters of the future roller bench, motorcycle mode metering was performed so as to assess the bearing structure loading when riding through the proving ground roads with special pavements. Further, the selection of the main bench parameters is justified, such as the range of trail and wheelbase of the object under test, diameters of the rollers and method of their rotation rate measuring, dimensions, geometry and number of obstacles, drive power, etc. A system of motorcycle ballasting and holding on the bench is designed. Potential errors when designing similar test benches are shown, their solutions are suggested. Statistical and spectral analysis of motorcycle loads recorded at the FSUE “NAMI” Testing Center proving ground was performed, and, based thereon, selection of single roughnesses for bench testing was made.

Practical significance. As a result of the conducted research, a roller bench, on which a motorcycle is currently being tested, was designed and manufactured. A foundation has been laid for methodical transition from road load tests to bench tests.
