Detailed introduction of no frill conical head
cone end
The big end of the cone and cylinder connection, should determine the connection of conical shell section thickness according to the following steps:
To determine the main connection diagram of cone shell to strengthen the
A. p/ ([s]tj) and half angle a value, check to determine cone connection to strengthen the main map: when the node in the above curve, without local reinforcement; when the node in the curve below, you need to strengthen the local.
B. no need to strengthen, the big end of the cone wall thickness according to formula (4-36) calculation
C. need to increase the thickness to be strengthened, it should be set up to strengthen the section between the conical shell and cylindrical, conical shell and cylindrical section thickness shall strengthen the same, strengthen section thickness calculation according to formula (4-37) Q- (4-37) in the calculation of stress increment coefficient, and p/ ([s]tj) related to a value, the at the end of conical shell connection map of Q value found, at the junction of the big end of the conical shell map of Q value of intermediate values by interpolation. The length of the reinforcing section of the cone shell should not be less than the length of L1, and the length of the reinforced section of the cylinder should not be less than that of L.
Small end of 2. pyramids
When the cone ends are connected with the cylinder, the design of small end cone wall thickness is based on the value of p/ ([s]tj) and half vertex a. The reinforcement diagram of the conical shell small end connection is determined, and the Q value diagram at the connection point of the conical shell end is not determined. When the intersection point is above the curve, it does not need to be partially strengthened. The calculation of D thick wall with big end. When its intersection is under the curve of the graph, it needs to be strengthened locally. The formula for calculating the thickness of the wall is the inner diameter of the small end of the Dis- cone in the formula, the mm and Q- stress increment coefficient, which is found out by the Q value diagram determining the joint at the small end of the cone shell. In any case, the thickness of the reinforced section should not be less than the thickness of the conical shell connected by the phase. The length of the reinforcing section of the cone shell should not be less than L1; the length of the cylinder strengthening section should not be less than that of L.
