Example text

The best previous visited position of the particle is denoted as pbesti = ( pbesti1 , pbesti 2 ," , pbestid ) . The velocity and the position of the particle are updated according to the following two equations: vijk +1 = w × vijk + c1 × r1 × ( pbestij − xijk ) + c2 × r2 × ( gbest j − xijk ) xijk +1 = xijk + vijk +1 (1) (2) Where j = 1,2, " d . Both r1 and r2 are random numbers, which uniformly distributed between [0, 1]. Both c1 and c2 are the positive constant, c1 = c2 =2 [5]. w is inertial weight calculated in the following form for a quick convergence and good result, w = wmax − iter × wmax − wmin itermax (3) Where, wmax and wmin are the inertial and final weights respectively.

The objective function is defined as a problem minimizing differences between the experimental and analytical modal results. The minimization of objective function is expressed as a bound-constrained nonlinear least-squares (BCNLS) problem as follows, minNe f (α ) = α∈R 1 1 N 2 r (α ) = ∑ ri 2 (α ) 2 2 i =1 l ≤ α ≤ u, r : R Ne →R (9) N r (α ) N ×1 = ⎡⎣ r f (α )TNm ×1 , rϕ (α )TNm ×1 ⎤⎦ T (10) Where r (α) = (r (α), r (α),… , r (α)) , is a N-dimensional vector-valued function, N = 2 N ≥ N .

The velocity of the particle can be represented by , another vector, vi = ( vi1 , vi 2 " vid ) . The best previous visited position of the particle is denoted as pbesti = ( pbesti1 , pbesti 2 ," , pbestid ) . The velocity and the position of the particle are updated according to the following two equations: vijk +1 = w × vijk + c1 × r1 × ( pbestij − xijk ) + c2 × r2 × ( gbest j − xijk ) xijk +1 = xijk + vijk +1 (1) (2) Where j = 1,2, " d . Both r1 and r2 are random numbers, which uniformly distributed between [0, 1].
