Abstract By the use of the extended finite element method the analysis of the random response of a linear structure to a continuous excitation field, random in time and space, is presented in this paper. The extended finite element method includes the formulation for obtaining the equivalent node force power spectrum. The corresponding computer program has been produced. A random response analysis of a sluice gate support shows satisfactory agreement with the experiment results.

The Impact

The impact line is a remarkable disadvantage in the auto body panels forming. It is difficult to study because of the complexity shape of automotive panels. The finite element models of hyperboloid shallow shells that can represent automotive panels are established, and suitability of finite element analysis to induce the impact line of automotive panel is carried out. The experiment test method for determining impact line is presented also. The criterion and research technique of auto body panels impact line are introduced. The consistency of results of simulation and experiment shows that the numerical simulation on research of impact line is accurate and feasible. Finally, research works of simulation and experiment on controlling impact line measures are carried out: effects of blank holding force (BHF), sheet thickness and lubricating modes on the impact line are obtained.
