Belt drive cvt
Belt drive cvt
(OP)
I am constructing a MATLAB/Simulink model of a wind-turbine/cvt/DC-generator system. Initially, I will model the cvt as a belt-drive tranny with variable-radius pulleys. For this model, I need an estimate of a k-value (spring constant) for the belt. Does anyone know what some reasonable k-values are for belt-driven cvt's? Thanks!





RE: Belt drive cvt
The stiffness of a v belt will vary in proportion to the load it is designed to take. I haven't been able to find any solid figures, but I'd guess 1000 N/mm per mm of width per metre of length would be a reasonable starting point.
