There are various traditional methods,such as the finite difference method, the finite element method, the boundary element method etc.
また,板厚寸法のみならず,部材配置などを設計変数に含めると,有限要素法の利用は更に困難になる。
In addition, inclusion not only of plate thickness,but also disposition of members in design parameters makes the use of finite element methods more difficult.
In order to ascertain loading conditions and interior stress status that cannot be determined by tests,we carry out an analysis using FEM(Finite Element Method) to affirm the safety of the members.
In the case of the experiment-centered research, CAD design and FEM analyses are done in order to create new experiment devices. These devices are then manufactured at the NUT Machining Center and experiments are subsequently carried out.
Finite element method(FEM) can solve the mass conservation equation as close to zero for the weighted residual throughout the target area, however, it is difficult to guarantee the mass conservation of each and every fluid element in the model locally.
Beginning around 2000, however, finite element method software for general use gradually became available, and companies came to actively use this method as well.
Machine weighing 4 tons,variable analysis technique using structural dynamic design principle and finite element method designed machine base has excellent static and dynamic performance.
As the mechanical properties of each elementare changed as a result of these structural changes, the finite element method and PF method are performed again with these changes reflected.
