How do you deal with accidental tilt of accelerometer installation when measuring acceleration to identify mode shapes?

When estimating mode curvature, high accuracy is necessary, accidental tilt can be too large in this sense. Can it be compensated using gravity as reference o something similar?

Is there an analytical way to calculate the effective piston area when clearance between it and the cylinder is large?

In the case of an hydraulic cylinder where the piston has no seal and the clearance is large, I think the effective piston area is larger than the geometrical piston area and lower than the...

Is a flexible structure "output-strictly passive" when output is displacements, velocities and accelerations?

I am interested in a LTI system x_dot = A*x + B*u y = C*x + D*u (M*q_ddot + C*q_dot + K*q = f) such that f = vector of external forces q = vector of displacements u = [0 f^T 0]^T x = [q...

Where can I find raw data from some Structural Health Monitoring campaign carried out in a bridge?

Preferably, I am looking for acceleration signals. Some papers mention rae data is available in some institutional webpages. Unfortunately, those page are not working any more.
