This paper deals with multimode oscillations in the selfstarting van der pol oscillator system, using the equivalent linearization technique of kryloff and Bogoliuboff, the digital simulation method, and the electronic hardware simulation method, respectively. This system consists of three sections of van der Pol oscillators which are characterized by fifth-power nonlinearity and coupled by two inductors. This paper points out that in such a system the simultaneous three-mode oscillation may be excited stably in addition to the single-mode and simultaneous double-mode oscillations. Which of the above oscillations is excited actually? It is dependent on the value of the parameter ∈. A new method using an electronic system of orthogonal transformation for observing the multimode oscillations is introduced in this paper as well.

Stochastic dynamic response analysis of fixed offshore platforms to nonlinear random wave forces is represented systematically. Effects of fluid-structure interactions are considered. The main problems which should be solved are linearization of nonlinear drag forces and diagonalization of coupled general damping matrices. Statistic equivalent linearization technique is therefor used together with an iterative proeedure. The simutaneous nonlinear stochastic differential equations are finally transformed into several independent linearized ones and are then solved readily. SELIM and SELIM-1 computer programs are developed accordingly. The calculation results are satisfactory. For an offshore tower with seven degrees of freedom, the iterative errors become less than five persent after two or three cycles of iteration.
