The results show the predictions of the model to be in general agreement with observations of motorcycle behaviour from the field and they suggest that frame flexibility remains an important design and analysis area, despite improvements in frame designs over recent years.
The new model is used for steady turning, stability, design parameter sensitivity and response to road forcing calculations.

This area can be considered as software in the software. In particular, the " Magic Formula " motorcycle tyre model is utilised and complete sets of parameter values for contemporary tyres are derived by identification methods. Motorbike Chassis Geometry calculation - Motorbike Design by NT-Project. You can then apply these changes to the motorcycle giving you the proper geometry setup based on your riding skill/style, frame anomalies, tire manufacture and size, suspension components etc. These concern (a) tyre/road contact geometry, (b) tyre shear force and moment descriptions, as functions of load, slip and camber, (c) tyre relaxation properties, (d) a new analytic treatment of the monoshock rear suspension mechanism with sample results, (e) parameter values describing a contemporary high performance machine and rider, (f) steady-state equilibrium and power checking and (g) steering control. Using the system, we are able to simulate changes to the bike to see how they affect the geometry stance. Type the name of the structure to see what data it contains.Starting from an existing advanced motorcycle dynamics model, which allows simulation of reasonably general motions and stability, modal and response computations for small perturbations from any trim condition, improvements are described. Note that the model logs relevant data to MATLAB workspace in a data structure called sldemo_suspn_output. As a sanity check, think about a bike like a 2004 R1 that has almost exactly a 2:1 leverage ratio. Loading initial conditions in the model workspace prevents any accidental modifications of parameters and keeps MATLAB workspace clean. In the Model Explorer, look under the contents of the sldemo_suspn model and select "Model Workspace". To see the contents of the model workspace, in the Simulink Editor, on the Modeling tab, under Design, select Model Explorer. Initial conditions are loaded into the model workspace from the sldemo_suspdat.m file.

To run this model, on the Simulation tab, click Run. The first step in either building a 4-link suspension or troubleshooting an existing suspension is to download one of these Triaged calculators created by Dan Barcroft and plug in the dimensions and weights it asks for. Thus, Kf, Cf, and -Lf are used for the front suspension block whereas Kr, Cr, and Lr are used for the rear suspension block. Furthermore, L is thought of as the Cartesian coordinate x, being negative or positive with respect to the origin, or center of gravity. Because the subsystem is a masked block, a different data set ( L, K and C) can be entered for each instance. The differences between front and rear are accounted for as follows. The equations are implemented directly in the Simulink® diagram through the straightforward use of Gain and Summation blocks. From suspension setup to saddle height, this guide will show you the basics of bike setup. The suspension subsystems are used to model Equations 1-3. Right click on the Front/Rear Suspension block and select Mask > Look Under Mask to see the front/rear suspension subsystem. The spring/damper subsystem that models the front and rear suspensions is shown above. Using the system, we are able to simulate changes to the bike to see how they affect the geometry stance.
