1. Setting up the dynamic model

1.1 Setting the context

The quality of rotation transmission is the most important parameter for most belt drives: reduced transmission error, etc. . In addition, the toothed belt drive must not exhibit any harmful parasitic behavior: limitation of strand vibrations, etc. The overall dynamic response must therefore be satisfactory at all speeds. In this case, the overall dynamic response must be satisfactory for all rotational speeds and, should this objective not be achieved, palliatives are introduced: tensioner, etc. In this way, a rotational dynamic model is built, considering phenomena that are decoupled, on the one hand, from the predominant effects of pulley rotation and, on the other hand, from limitations, notably on string vibrations represented by free...
