Mike Pogue Mar 7, 2016 4:58 PM (in response to Frank Schoenherr)Can you show the dimensions of the model? Also, what is your source for the hand calc?


Re: Simulated displacement incorrect based on manual calculation
Ryan Navarro Mar 7, 2016 8:12 PM (in response to Frank Schoenherr)Both ends are effectively fixed in the simulation which will impart extra stiffness when compared to the simply supported assumption. Perhaps a better hand calculation to match the simulation would be to use a beam bending calculation for a beam fixed at both ends with uniform loading. The equation for maximum deflection in that case is ( F*L^3 ) / (384*E*I) or a factor of 5 less than the simply supported beam equation you posted.
That being said you should question which boundary condition is more representative of the real world application.

Frank Schoenherr Mar 7, 2016 9:35 PM (in response to Ryan Navarro)Hi Ryan,
That is the solution! Then I am wondering how am I able to simulate it in SLX? I am certain that both ends are not fixed and are like a rolling bearing.
Thank you
