Abstract

A structural part, especially a shielding component, has structural parts (10, 12, 14, 16) at least in part differently configured with respect to their surface extent and/or the directional pattern. At least one structural part (10) of a first type is provided with a curvature at least partially increasing in the direction of at least one edge area (20). Structural parts (12) of a second type at least in part follow the curvature (18) of the first structural part. In each curved edge area (20), at least one structural part (14) of a third type is provided, according to the position in which the structural parts (12) of the second type are oriented and extend continuously at least in the area of the change in the curvature toward the edge area (20) along the first structural part (10). The edge area is strengthened by an additional structural part which, in addition to low-vibration behavior, leads to a clear reduction of acoustic propagation of noisy engine components.
