The paper first introduces the concept of inherent strain and the theory and method of predicting welding deformation by the inherent strain finite element method. Studies have shown that the inherent strain exists in the weld and the near seam area, and it is also related to factors such as welding heat input and plate thickness. Through the use of large-scale finite element simulation software ANSYS, the inherent strain finite element prediction method is applied to the welding deformation of the outer gantry assembly material of forklift, which provides effective reference data for future welding work of forklift gantry materials.

High sound insulation performance of a wall is one of the significant goals of the architecture design. For exploring a reliable sound insulation prediction method to a single-leaf wall, this paper introduces the coincidence effect in the calculation. This method can predict the wall’s sound reduction index easily, and depict the coincidence effect of a wall especially. Meanwhile, it is shown that the prediction method might be applied to the practical building acoustic design.
