parameterization of location of cross-members of ladder frame chassis

Mahesh Agrani

Dear all,
please help me with the parameterization of LOCATION of three cross-members of ladder frame chassis for DOE study using LHS(random design points). The cross-members are to be translated in y-direction in both directions limited to ±100 units. The design variables (continuous, not discrete) are the locations of cross-members from rear end i.e. Y1, Y2 and Y3 and response is the first modal frequency. I want to generate a response surface for freq in terms of Y1, Y2, and Y3. Please tell me how to parameterize their locations to be varied as continuous variables if possible or otherwise to create response surface.

Desired shape change of cross member can be done using morphing>create 3 shape variables for cross member and export as tpl file.(By default after importing tpl file the mode would be set to continuous)

You can refer HS-4420 tutorial.Once you have all 3 DV in HyperStudy, then by performing nominal run you can have frequency as response. Then further you can perform DOE and Optimization.
