Hi,
I have to determine the first eigen frequencies of a wind turbine placed on the sea bed (north sea). Interaction with the sea bed has to be investigated. My first idea is to model the stiffness of the soil with springs. (and leave the mass of the soil out). Does anybody have experience with...
Hi,
For a project i have to analyse the first eigenfrequencies for a windturbine placed on the sea bed. Problem: how do i model the influence the stiffness of the sea bed. My first guess is to model the stiffness with springs. WHat is a good first estimate of the stiffness of the seabed? Where...
Hi
I need a steel strip (St52) (thickness10mm, height 60mm)to use as a guide rail for a curved door. The strip is 2.5m long, and has two radii. First part radius: 3.5m, 2nd part radius: 0.35m).
I am thinking of making this rail by rolling the strip. What tolerances can be met with the rolling...
Hi,
We bonded carbon composite (CF-epory) to aluminium with 3M EPX DP490 adhesive (epoxy). A metal primer (epoxy, also from 3M) was used for corrosion protection (galvanic corrosion). On test samples we saw green residue on both the CFRP and the aluminium, indicating that the primer itself had...
