Developing the Model and Environment for Evaluating Ride Quality of Cyclists

Ride quality is an important factor in vehicle performance evaluation. Many parameters including flexibility of vehicle body components, tires, and mounts, as well as mass distribution and the pavement features affect the vehicle performance. The most commonly used models for ride quality analysis use sprung and unsprung masses as rigid bodies (lumped masses) or as flexible beams (simplified distributed masses). These models are used to calculate the frequency weighted root mean square (RMS) accelerations experienced at the driver’s seat and compare with the ISO 2631 comfort curves. With advances in computer and simulation technology, automakers have started using full-flex body models. With the current emphasis on non-motorized mobility, cycling is promoted. So far, there is very limited work conducted on evaluating the ride quality of cyclists. The research on cyclists’ ride quality analysis is primarily experimental based. Experimental research requires significant resources, manpower, and time to generate implementable results. Further, with experimental investigations, the analysis capabilities and parameters are limited. Having access to high fidelity simulation models helps reducing the cost of investigation, developing robust and effective experimental programs, and evaluating product development and life-cycle performance for delivering implementation ready results. Hence, this research is proposed for developing the model and environment for evaluating ride quality of cyclists.
