Abstract:

The paper presents theoretical and experimental analysis of the induced and cripplingstress and strain of the external link on the camshaft chain of a Direct Injection Dieselengine. For the experimental tests, tensometry and photoelasticimetry were used in orderto obtain an overall image of the induced stress state. For the present time, the authorscould not find an analytic solution but in the limits of some hypotheses far from thereality. That is why, the experimental results was followed by a numerical analysis, usingfinite elements method. The values obtained after the model running using F.E.M.,correspond with the numerical results, so the devices used are validated, and may beused as standards for further researches in future.
