That is the so-called eigenvalue sensitivity and eigenvector sensitivity ,(m=1, 2….) indicate structure design parameters (mainly refers to the size of the structure, geometry shape or material parameters, also including mass, stiffness and damping elements) or design variable.
Taking the five main parameters of the crankshaft such as thickness of crank arm (Th_cr), diameter of main journal (D_mj), length of main journal (L_mj), diameter of crank pin journal (D_cpj) and length of crank pin journal (L_cpj) as design parameters, the sensitivity of the first five-order constraint frequencies versus the five design parameters is calculated.
