Based on the Structure and wind load force characteristics of the vehicle mounted extensible mast system, a test method for the wind load simulation of the system was designed. According to the thin wall part structural feature, a method that adding lateral tension at the flanges of the mast was used to simulate wind load. Calculation method of the theoretical wind load force was given, and the transformation formulas between loading force needed and theoretical wind force was put forward, as well the control method of the test based on PID control algorithm was described. Simulation of the force condition under trapezoidal load was given by ANSYS. The results showed that using the load scheme designed, the distribution of stress and strain was almost the same as continuous load, as well as the value and position of the maximum stress and strain.

ABSTRACTWe study dynamics, structure and organization of the new paradigm of wavewrinkle structures associated with multipulse laser-induced RayleighTaylor (RT) instability in the plane of a target surface in the circumferential zone (C-zone) of the spot. Irregular target surface, variation of the fluid layer thickness and of the fluid velocity affect the nonlinearity and dispersion. The fluid layer inhomogeneity establishes local domains arranged (organized) in the «domain network». The traveling wavewrinkles become solitary waves and latter on become transformed into stationary soliton wavewrinkle patterns. Their morphology varies in the radial direction ofaussian-like spot ranging from the compacton-like solitons to the aperiodic rectangular waves (with rounded top surface) and to the periodic ones. These wavewrinkles may be successfully juxtapositioned with the exact solution of the nonlinear differential equations formulated in the KadomtsevPetviashvili sense taking into account the fluid conditions in particular domain. The cooling wave that starts at the periphery by the end of the pulse causes sudden increase of density and surface tension: the wavewrinkle structures become unstable what causes their break-up. The onset of solidification causes formation of an elastic sheet which starts to shrink generating lateral tension on the wavewrinkles. The focusing of energy at the constrained boundary causes the formation of wrinklons as the new elementary excitation of the elastic sheets.

The Basic Theory of the deflection of long, thin plates under normal pressure is extended to cover the effects of initial lateral tension or slackness in the plate and the effect of deformation of the supports at the edges of the plate under the lateral tension developed. The procedure is illustrated by application to a case of a plate under initial tension with its edges held apart elastically, and the computed values of the strains are compared with values measured experimentally. The application to an initially slack plate is also illustrated by a diagram.
