“…Estimated forces were validated through experimental data acquisitions. In [32,33], the authors instrumented the handlebar of a motorcycle with three-axis rosette strain gauges in order to obtain strain histories on several roads. The strain histories were then used as input for a servo-hydraulic actuator to obtain accelerated durability tests.…”

The paper is devoted to the measurement and to the processing of load spectra of forces and moments acting at the wheel hub of a motorcycle. Smart wheels (SWs) have been specifically developed for the scope. Throughout the paper, the extreme case of a race motorcycle is considered. Accurate load spectra were measured in two race circuits. Standardized load spectra are derived by processing measured data. A way to easily generalize the measured load spectra is proposed for the first time for motorcycles. Several loading conditions, related to the motorcycle straight line motion, cornering, curb hit and gear shift, are identified and extracted from the experimental measures. For each loading condition, by means of simple semi-analytical models (SAMs), a relationship is found between the vertical force on the wheel, the tilt angle of the motorcycle and the remaining forces and moments acting at the wheel hub. Such relationships are nothing else than the standardized load spectra. Additionally, a simple and efficient method based on smart wheels for real-time structural monitoring is proposed. Standardized load spectra prove to provide consistent results even when compared to real-time structural monitoring data. By means of the presented smart wheels, advanced lightweight motorcycle construction is enabled by derivation of standardized load spectra or real time estimation of the damage of structural components.

“…The S-N approach, rainflow cycle counting method, Miner damage accumulation rule, Eurocode 3 standard, BS 5400 standard, and Gurney thickness modified equation were employed for fatigue life evaluation [33]. Comparison between the experimental and predicted fatigue lives of motorcycle handlebars subjected to full length and edited histories, including three road types and four damage levels, were employed to evaluate the effect of these two signal condensation techniques.…”

The rapid development of the vehicle industry has made reducing product development time a major concern. This study seeks to identify a suitable accelerated approach to durability analysis for motorcycle components. This investigation involves field data acquisition, laboratory road load simulation, accelerated durability testing, and fatigue life prediction. Two methods, 'strain range editing technique' and 'racetrack editing technique', were applied to edit field strain histories for accelerated durability tests. Furthermore, four methods, including the 'S-N approach with fatigue property of base metal', 'Eurocode 3 approach', 'BS 5400 approach', and 'BS 5400 approach with Gurney thickness modification', were employed to assess fatigue life. Three road types and four damage levels were also used. The results demonstrated that the 'BS 5400 approach with Gurney thickness modification' is a suitable method of assessing the durability of welded motorcycle components when the fatigue properties of critical points are not available. Both the 'strain range editing technique' and 'racetrack editing technique' can effectively edit strain histories with the expected quantity of fatigue damage, and demonstrate satisfactory agreement between the experimental data and predicted data.

“…Balakrishnan [12] discussed the optimization of motorcycle's center stand, and established the correlation among various customer usage patterns, accelerated endurance tests, and fatigue life prediction results using both experimental data and finite element models. Lin [13] employed the fatigue life prediction method and durability experiments to investigate the fatigue failure of motorcycle handlebars. Goktan [14] measured the road load data and evaluated the vibration of exhaust system on the multiaxial test rig.…”

The durability and riding comfort performance of a new type scooter were investigated by bench test. The longterm road load data of Taiwan market were measured with accelerometers and strain gauges by the on-line rainflow cycle counting method. The equivalent test track corresponding to 50,000 km in Taiwan market was established with ARTC's proving ground (Automotive Research and Testing Center in Taiwan) by correlation analysis technique. Then we performed the full vehicle bench durability test with load histories obtained by the road simulation technique. After a series of testing, analysis, and modification, the test vehicle already got a satisfactory result for the durability performance. Riding comfort analysis was performed following the ISO 2631 standard with accelerometers near the seat and foot in the bench testing. In order to get an optimum combination of suspension system for this new type scooter, many sets of front and rear suspensions were evaluated. The evaluation software of riding comfort was developed in accordance with ISO 2631 standard by using LabVIEW programming language. Finally, no cracks were observed when this scooter underwent a durability test on the public road more than 50,000 km. It means that above integrated approach was suitable to evaluate the durability and riding comfort performance of a new type vehicle.
