Be made as curved surface by at least one surface with air filter or resonator, its surperficial mode of raising of energy higher amplitude, thereby improve its radiated noise level on car load is used, require lower to mould and Shooting Technique simultaneously, and be conducive to reduce pts wt and cost with respect to prior art, have certain performance advantage and cost advantage.
Below with reference to Fig. 1-6 curved surface acquisition process of the present invention is described.
For the sake of clarity, stiffening rib is not shown in Fig. 1-5, can be referring to Fig. 6 about stiffening rib.
As shown in Figure 1, initial end face, bottom surface and each side thereof of air filter or resonator is the plane, and these planes and stiffening rib can be with the manner known in the art combinations.
For obtaining described curved surface, set at first first each surperficial thickness and the stiffening rib of air filter or resonator, each surperficial curvature parameters of preliminary settlement again, carry out again computer aided analysis (being called for short CAE), utilize software simulation (for example, can adopt MecalogRadioss, Ansys, the softwares such as MSC Natran carry out) described curvature or curve form are optimized, therefrom draw curvature parameters and the scheme thereof of an optimum, to improve the surperficial mode of air filter or resonator.Below will specifically describe corresponding curved surface acquisition process.
When carrying out the three-dimensional modeling of air filter or resonator, on a certain surface of its initial digital-to-analogue, provide the camber line of three or many different curvature radius, be drawn into respectively three or more curved surface by these three or many camber lines again.For example, for the simple scenario that is drawn into a curved surface by a camber line, can be by making this camber line mainly along the mobile curved surface that forms of its normal orientation (or be less than an angle of 90 degrees degree direction with direction); For the situation that is drawn into curved surface by the two or more pieces camber line, the method that forms curved surface is: take (or many) camber line as section line, scan along another (or many) camber line (guide wire) and to form.Cut respectively initial three-dimensional digital-to-analogue with described three or more curved surface again, form three or more three-dimensional digital-to-analogue with different curvature surface (three or more scheme), guaranteeing other parameter and condition (thickness of shell for example, material is selected, serviceability temperature etc.) under the identical condition, utilizing first Hypermesh to carry out the discretization grid to this three or more scheme respectively again processes, re-use MecalogRadioss or other software carries out computer aided analysis, study the trend that affects and the rule thereof of different radius of curvature effects on surface mode, to obtain to have the scheme of highest face temperature mode, determine thus optimized radius of curvature.
See also Fig. 2 and 3.Produce some the camber lines (such as camber line 1-6) of setting curvature (or radius) at the end face of air filter or resonator, make each camber line and each tangent side corresponding one by one.Its meanline curvature (radius) is determined through the CAE optimality analysis.
See also Fig. 4.Some camber lines among Fig. 2 are scanned into a curved surface, again with air filter or resonator end face and this application of a surface, or prune the end face of air filter or resonator with this curved surface.Therefore, air filter or resonator end face become the curvature end face of controlling through curvature parameters by the plane, and such as curvature end face 7, its surperficial mode will be highly improved.
See also Fig. 5.Camber line among Fig. 3 is pressed certain orientation stretch, form several curved surfaces.Again each is fitted with it with curved surface to the side, or prune each corresponding side with these curved surfaces.Therefore, each side of air filter or resonator becomes the curvature side of controlling through curvature parameters by the plane, and such as curvature side 8 and 9, its surperficial mode will be highly improved.
