Oct 23, 2024 · To calculate the deflection of a beam follow these steps: Determine whether it is a cantilever beam or a simply-supported beam. Measure the beam deflection from structure deformation. Choose the appropriate beam deflection formula for your beam type. Input your data including beam length, the area moment of inertia, modulus of elasticity, and ...
- 0 Differential Equation of the Deflection Curve. The differential equation of the deflection curve is used to describe bending behaviour so it crops up when examining beam bending and column buckling behaviour.
- 0 Determining the Bending Moment Equations. Consider the simply supported beam in Fig. 1 below. The beam is subject to two point loads and a uniformly distributed load.
- 0 Integrating the Differential Equation of the Deflection Curve. Now that we have established how the bending moment varies, we can substitute our relevant expressions for M(x)M(x)M(x) into the differential equation and perform our integrations.
- 0 Calculating Beam Deflection. At this point we can summarise the three equations that describe the deflection in the three regions of our beam: EIv=−10x412+139.375x36−856.354x (Region 1)(22)EI v = -10\frac{x^4}{12} + 139.375\frac{x^3}{6} -856.354x \:\:(\text{Region } 1) \tag{22}EIv=−1012x4+139.3756x3−856.354x(Region 1)(22)
Beam deflection calculations can be used to determine the maximum deflection of a linear guide or actuator that isn't fully supported along its length.
