Composite optimization of automotive carbon fiber strut bar using hyperworks optistruct

Front strut bar is an automotive part commonly used for McPherson suspension system to minimize load on the strut tower by tying both left and right strut with a single bar. By distributing the force acting on a single strut to both strut tower, the strut bar minimizes the chassis flex which improve...
