Manufacturing model• 2.5mm sheet with aluminum alloy • 2.5mm sheet with aluminum alloy

Outer face with offseted FEA model

Direct Frequency response analysis

(0-1600hz with cosine function)1. Direct frequency response analysis:-

I. Magnitude and the location are same as static analysis with a function of cosine with phase 250 and frequency range 0.0 to 1600hz.

II. Boundary condition is same as static analysis.

Load and boundary condition in direct frequency response analysis

Load and boundary condition for static x-directional loading

Load and boundary condition for static y-directional loading

Load and boundary condition for static y-directional loading

Load and boundary condition for direct frf x,y,z-directional loading

Full constrained areaLoad as per static analysis with frequency function

Load and boundary condition in direct transient response analysis
