Join Tony Abbey for an in-depth discussion in this video Pre-stiffened normal modes, part of SOLIDWORKS Simulation: Dynamic Analysis.
- [Instructor] In this video,…we're going to review pre-stiffened normal modes analysis.…Now, many real-world components…are subject to some kind of pre-load,…or they might develop steady state loads…during their operation.…For example, we've got pre-tensioned bolts.…Imagine a transmission tower which is braced to ground…by heavily pre-stressed guide wires.…And a helicopter rotor blade when spinning…has a tremendous level of centrifugal force…which really stiffens that blade up.…
That's the example we're gonna be using…in our demonstration video…which is coming up shortly.…Now, the pre-stiffening effect,…and if we look at the helicopter blade here as an example,…it's spinning about the spin axis,…it develops a very high load within the structure.…The linear stiffness matrix that we calculate…is unaffected by this,…so we'd call that linear stiffness matrix.…But then we have a load dependent stiffness matrix,…and that's actually changing.…So that's the stiffness matrix dependent…on the loads which are developed.…
As the tension increases,…
