This paper presents a simple model for predicting the transmission of bending waves from one leaf of a cavity wall to the other via a strip foundation. It accounts for both the inertia effects of the foundation and the stiffness of the soil and the results show reasonable agreement with measured data obtained from a small test wall supported on a concrete strip foundation.

Golden Section Method

Due to the optimization problem of coating thickness uniformity for two times spray technology, an optimization method of coating thickness uniformity for two times spray technology was proposed based on the optimized spray trajectory of one time. Based on the established tool model and complex curved surface was partitioned into several plane patches, the model of coating thickness was established for two times spray on the plane. The optimization model of coating uniformity was given and the golden section method was used to solve it. Simulation result show that the feasibility and availability of optimization model; the coating uniformity was improved effectively after optimization for two times spray trajectory.

Simulation Results

We attempt to resolve the spray trajectory planning efficiency and the coating thickness uniformity for big curvature surface on complex curved surfaces. The least square method was proposed for spray partition of complex curved surface based on topology partition. First, the big curvature surface was extracted from complex curved surfaces. Then, the big curvature surface was fitted into the natural quadric surface based on least square method and the fitting algorithm was given. Simulation results show that, the fitting algorithm is feasible, and this method can effectively reduce the number of patches, which can improve the spray trajectory planning efficiency and the coating thickness uniformity.
