A grating including a bar assembly having bearing bars with a unique cross section connected to one another with crossbars. The bearing bars are generally hourglass-shaped in cross section and include a first region, a second region, and a third region interposed therebetween. The first and second regions flare outwardly away from opposite ends of the third region. The ends of the first and second regions are of a first width and the third region is of a smaller second width. First and second side sections of the third region connect to each of the first and second regions at an angle of greater than 90 degrees. Channels for the crossbars are defined in a first end of the first region of the bearing bar or form a hole extending from a first side section to a second side section of the third region of the bearing bar.

The invention relates to a novel stable node integral calculation method based on hourglass control, and the method comprises the steps: dividing a problem domain into a triangular or tetrahedral mesh, and dividing a mesh integral domain into a plurality of non-overlapping node integral domains based on nodes in the triangular or tetrahedral mesh; performing node domain smoothing on the node integral domain based on the triangular / tetrahedron strain component of the node to obtain a smooth domain; hourglass control between a node and an adjacent node is constructed in the smooth domain, and hourglass force between the node and the adjacent node is calculated; and superposing the hourglass force borne by the node with the original internal force calculated by node integration to obtain the internal force of a stable node integration method, and solving a discrete motion equation in explicit dynamics based on the internal force of the stable node integration method to obtain a dynamic response. According to the method, the calculation precision based on the unstructured grid is greatly improved, and the advantages that the number of integration points of node integration is small and the grid distortion resistance is high are effectively kept.

In a rotary hourglass, it is an issue to simplify the rotation method of a support frame SS having a sand container for inverting the vertical positions of the sand containers. 【Solution means】 Three sand containers 3 and a support frame SS of the sand containers having a pipe for passing sand therebetween have a rotation axis parallel to the Y-axis of the XYZ three-dimensional orthogonal coordinate system. The above-mentioned support frame SS has a form having a plurality of acting points for applying a force MF in the rotation direction TD to rotate the support frame SS. In order to move the container in which the sand has fallen to the upper part, when rotating the support frame SS by 120 degrees, a certain acting point is pushed with a force MF in the rotation direction TD to rotate the support frame SS by 60 degrees. Then, by further pushing another acting point with a force MF in the rotation direction TD, the support frame SS is further rotated by 60 degrees. By these means, the container in which the sand has fallen can be moved to the upper part, time measurement can be performed, the acting points can be pushed in the same direction, and the rotation method can be simplified.
