You will compute a Transient Dynamic Analysis by defining a load excitation on a hood. You will have to compute successively a static analysis, a frequency analysis and to finish, the dynamic response analysis. Restraints are fixed. The modulation will be applied on loadsThis exercise is composed of 3 main steps:Define and compute the static caseDefine and compute the frequency caseDefine and Compute the Transient Dynamic Response AnalysisThe mesh and the modulation file are provided
Load the pre-meshed hoodIn the pre-define Static Case:Apply Restraints using Advanced Restraints toolRestraint the 2 hinge holesMesh part: AllFix every translations (1,2,3) Fix rotation 1 and 3Restraint the front of the hoodMesh part: AllUnder the front hood, select the 2 inner edges of the holes ( see below) Use a User Axis system: Axis System.1Local Orientation: CartesianFix the translation 2 onlyPart used: Transient_dyn_analysis_step1.CATAnalysis
