Abstract
To analyze the operating loads and also the handling qualities of full supsension mountain bikes in off-road use, a simulation model representing all important effects is required. Most bicycle models discussed in literature are quite elementary. These models are adequate for analysing the general dynamic behaviour of bicycles but they are not capable of showing all effects appearing in off-road operation of mountain bikes. In this paper a detailed three-dimensional multibody model of a system consisting of a full suspension mountain bike, a passive mass-spring-damper system for the rider, stochastic track excitation and a control system for the velocity and lean angle stabilisation is presented. Additionally first results for straight driving of geometrically different mountain bikes are presented and discussed. Although a experimental validation of the model has not been performed yet the first results indicate that the development of the presented model is a first step for simulation based evaluation of handling qualities and operating loads for mountain bikes.
