Which is the best way to calculate deflection of a beam?
The component’s own weight can almost always be modeled as an evenly distributed load, while evaluating the applied load as a point load at the location of maximum deflection (at the free end of a cantilevered beam, or at the center of a simply supported beam) will generally provide the worst-case scenario for total deflection.
What is the impact factor of a beam?
The beam is steel (E = 200 GPa) with a rectangular cross‐section area having a width of 60 mmand a height of 30 mm. The first example causes an Impact Factor of about 6. The second example will yield an Impact Factor above 1,200. SolidWorks Finite Element Simulation:
What causes maximum deflection of telescoping bearings?
Deflection of cantilevered beams Telescoping bearings are often cantilevered, and some Cartesian robot configurations result in a cantilevered actuator on the Y or Z axis. In this case, the beam’s weight, which is reasonably uniform along its length, causes maximum deflection at the end of the beam.
How is energy balance used to estimate static load?
In the study of the mechanics of solids, an energy balance approximation is used to estimate the required static load. That approximation assumes that all of the kinetic energy of the moving mass is converted, with an efficiency of 𝜂, to strain energy in the body.
How is the deflection of a linear shaft calculated?
Deflection of simply supported beams. Linear shafts and actuators are often secured at their ends, leaving their length unsupported, much like a simply supported beam. The uniform load on the beam, (the shaft or actuator’s own weight), will induce maximum deflection at the center of the beam, which can be calculated as:
How is the stiffness of a beam determined?
We can define the stiffness of the beam by multiplying the beam’s modulus of elasticity, E, by its moment of inertia, I. The modulus of elasticity depends on the beam’s material. The higher a material’s modulus of elasticity, the more a deflection can sustain enormous loads before it reaches its breaking point.
For every calculated normal stress there is a corresponding induced shear stress; the value of the shear stress is equal to half that of the normal stress. Circular Cantilever Beam in Direct Tension and Bending Stress Equations and Calculator Circular Cantilever Beam in Direct Tension.
