The present paper describes the studies of vibroactivity of FEM models of gear transmission housings. The FEM model of the gear transmission housing installed on a laboratory stand was modified in order to reduce its vibration level. Two different variants of the housing ribbing are presented herein. The models were subjected to load exerted by dynamic forces in bearing nodes, determined by means of a dynamic model of a gear transmission in a powertrain. The measure of vibroactivity v2avg as defmed in the publication, was used for the quantitative comparisons. The studies performed proved that the models, depending on the location of ribbing, exhibit various vibroactivity rates, usually lower than those achieved in the basic, unribbed models. That was proven by analyses carried out for various load rates applied to the transmission. Furthermore, the paper presents the results of studies of sensitivity of FEM models o f gear transmission housings to excitation by dynamic forces in the meshing, depending on the precision of gears. The studies confirmed an increase in vibroactivity of toothed gear housings along with an increase of gear inaccuracies.
