Re: Single friction bearing element
Hello, In its basic form, horizontal displacement-force relationship of single concave Friction Pendulum bearing can be formulated as follows: F(u)= (N/R)*u + (Mu*N)*sign(udot) where F: horizontal force, u: horizontal displacement, udot: velocity, N: axial load on the bearing, R: effective radius, M...
