In this paper, an approximate solution for quasiconservative system is presented. Because the solution is the perturbation solution based on the nonlinear solution, strongly non-linear vibration systems can be solved by it. The solution is used to find the limit cycle of lienard's equation with a strongly non-symmetrical restoring force term, and give the calculating formulate of the limit cycle amplitude in each case. The effect of the restoring force term on the limit cycle is discussed. A second...

In this paper, an approximate solution for quasiconservative system is presented.

The solution is used to find the limit cycle of lienard's equation with a strongly non-symmetrical restoring force term, and give the calculating formulate of the limit cycle amplitude in each case. The effect of the restoring force term on the limit cycle is discussed. A second method proposed here is an improvement of harmonic balance technique. The method is the hybrid of harmonic balance technique and Galerkin's method.

Film thicknese and pressure distribution on the varied loads are calculated by the new method. The accuracy of numerical solution is much better than that calculated by Newton-Raphson method and C.P.U. time is greatly saved.

In the engineering field we arc often faced with a problem that from test data is determined a non-linear curve which is strongly non-linear and not expressed by an analytical formula ,c. g. it is absolutely necessaryin aircraft flight test data analysis that from flight test data is determined a polar diagram (curve) which is a basic aerodynamic characteristic curve to calculate a flight performance. The above problem may be included in non-lincar curve identification. In this paper research on a non-linear maximum likelihood-optimization method for identifying the non-linear curve is presented. A general idea of this method is : first the non-linear curve is approached by a suitable function system(e. g. a cubical spline-polynomial);secondly the non-linear curve identification is transformed into a normal parameter identification; thirdly a criterion of a maximum likelihood function is built; finally is established a unified successive iterate procedure that a criterion of the maximum likelihood function is driven into an extreme using an optimization method. This method has a uniqueness and a good astringency of the maximum likelihood method and a capability of solving a non-linear problem by the optimization method. An identified function curve (c. g. a cubical spline function curve) can approach the non-linear curve unlimitedly smoothly. In this paper a fundamental principle of this method and its application to identify above polar curve of an aircraft are presented.
