摘要： A computerized simulation method for evaluating a tire performance is disclosed. Firstly, a simulation of a rolling tire is made by contacting a tire model with a road surface model, and chronological data about node points of the tire model which node points appear in the outer surface of the tire model during rotating are stored. Then, a domain of a fluid is defined, and a simulation of the fluid is made by the use of the chronological data, wherein a small gap is formed between the tire model and the road surface model, and the fluid domain is also defined in the gap.

摘要： An apparatus for vulcanizing a tire comprises: a side mold segment provided with a face for shaping the outer surface of a tire sidewall portion, and an opposite face not serving for shaping; and a heater part for vulcanizing the raw tire. The heater part is disposed adjacently to the side mold segment to heat the raw tire abutting on the side-shaping-face from the side of the face not serving for shaping. The side mold segment is provided with a flow path through which a first fluid whose temperature is lower than the vulcanization temperature of the raw tire can flow to prevent over-vulcanization of the sidewall portion.

The curvature radius R2 of the second circular arc 68 is larger than the curvature radius R1 of the first circular arc 66. The first connection line 70 is a straight line. The first connection line 70 connects one end 78 of the first circular arc 66 to one end 80 of the second circular arc 68. The second connection line 72 is a straight line. The second connection line 72 connects the other end 74 of the first circular arc 66 to the other end 76 of the second circular arc 68. Preferably, the length L of a longest line segment that can be drawn within the contour of each dimple 62 is larger than the sum of the curvature radius R1 of the first circular arc 66 and the curvature radius R2 of the second circular arc 68.

摘要： A method for simulating a rolling tire and estimating its noise performance is disclosed, wherein a tire model rolling on a rough road surface model is simulated, and coordinates of node points appearing in the outer surface of the rolling tire model are stored as time-series coordinates data. A small gap is formed between a tire outer surface model defined by the time-series coordinates data and a smooth road surface model. Then, a sound field filled with air is defined including the gap, and pressure variations of the air are computed.

摘要： A method for generating a two-dimensional mesh model of an object made up of a finite number of elements and provided with nodes is disclosed. Data about an original contour of the analysis object, including data about contour nodes are defined. The original contour is transformed by scaling up or down only in the direction of a predetermined first axis at a predetermined first scaling factor to obtain the transformed contour. Based on the contour nodes and additional nodes defined on the transformed contour, a primary mesh model whose contour is the same as the transformed contour is generated. By scaling the primary mesh model only in the direction of the first axis at a second scaling factor equal to the reciprocal of the first scaling factor, a secondary mesh model whose contour is the same as the original contour is generated.
