“…Designing the bicycle for performance or rider comfort is a more complex task than designing for sufficient strength, since, the interaction between rider and bicycle is involved (Lessard et al, 1995;Chang, 2002). Qualitative judgments such as 'too springy' or 'too stiff' must be quantified in terms of frame stiffness (Escalona and Recuero, 2012).…”

Bicycles continue to be a popular two wheeler mode of transportation even in the current era due to its nature in being environmental and entertainment friendly. This research in particular is conducted to study and analyze the structural stability of the cross country mountain bike frame with different rider loadings and materials. Three types of rider mass will be studied here, 60, 100 and 150 kg, each representing the common, medium and higher extreme weight range of user. The load will be distributed in several percentage break ups on the seat, paddle and handle as described in the study. The mountain bike frames structural performance is also evaluated with three different materials applied, namely titanium, aluminum and carbon fiber. The structure consisting of a standard diamond-shape crosscountry frame will be designed in a CAD modeling software, CATIA and pre-processed and post-processed in finite element simulation software, ANSYS. Analysis results from the numerical analysis are recorded in terms of stress plots, displacements and natural frequency values and mode shapes. Design optimization is performed on the regions indicating high stress plots to reduce the stress concentration and enhance the structural stability of the frame. Optimized design is validated again through numerical analysis.

“…As an example they demonstrated the stability analysis of an uncontrolled bicycle. Escalona and Recuero [76], for educational purposes, derived equations of motion for an uncontrolled bicycle in a differential-algebraic equation (DAE) form, transformed it to an ordinary differential equation (ODE) form and linearized these equations about a steady motion. As an example, the non-linear equations were implemented in Matlab-Simulink to make an interactive real-time bicycle simulator.…”

A review of the current use of multibody dynamics methods in the analysis of the dynamics of vehicles is given. Railway vehicle dynamics as well as road vehicle dynamics are considered, where for the latter the dynamics of cars and trucks and the dynamics of single-track vehicles, in particular motorcycles and bicycles, are reviewed. Commonalities and differences are shown, and open questions and challenges are given as directions for further research in this field.

“…The rear sideslip angle oscillates with the rear wobble frequency, and the front sideslip angle oscillates with the front wobble frequency.For comparison, the Dymola multibody software[12] is used to verify the linear model developed in this study. Given that Dymola version 7.4 does not have a tire model, the slip force model in Eqs (9).…”

Lateral forces are known to be important in motorcycle stability. These forces also affect the stability of bicycles. In this study, we focus on the influence of tire lateral forces on bicycle self-stability. On the basis of the work of Whipple, we develop a linear bicycle model, including front and rear wheel lateral forces, in symbolic equations of motion. Modal analysis and dynamic simulation of the bicycle model are conducted and used to examine self-stability. The lateral stability of a bicycle is characterized by two oscillatory vibration modes, namely, wobble and weave, and one non-oscillatory capsize mode. Tire sideslip force modeling reveals the wobble mode, and relaxation modeling reveals the rear wobble mode. At low speed, the unstable capsize mode dominates. At medium speed, the weave mode vibratory motion dominates. At high speed, the wobble mode dominates. The influence of lateral forces on self-stability is identified using the developed model. A nonlinear multibody bicycle model is used to confirm the results of the linear analysis.
