Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] combine figure 1 , figure 2 , image 3 and Figure 4 As shown in the figure, the design method of the symmetrical trifurcated beam bifurcated pipe includes the following steps:

[0048] Step 1, take the axis of the main pipe A and the bifurcation point 0 as the benchmark, and determine the bifurcation angle ω and the respective axes of the first branch pipe B, the second branch pipe C and the third branch pipe D according to the design requirements, ω<90°; design Requirements include design parameter requirements, which usually include design head, material density, material elastic modulus, material Poisson's ratio, etc.;

[0049] Step 2, design the basic cone; first, determine the maximum radius R of the main pipe A according to the design requirements A , the half cone angle α of the basic cone in charge of A A , the maximum radius R of the first branc...

Abstract

The invention belongs to the technical field of bifurcated pipes and their design, and specifically discloses a design method of a symmetrical trifurcated beam type bifurcated pipe and a symmetrical trifurcated beam type bifurcated pipe designed and manufactured by the method, aiming at solving the problem of existing symmetrical bifurcated pipes. The design method of the trifurcated beam bifurcated pipe requires high experience of the designer. According to the design requirements, the design method of the symmetrical trifurcated beam type bifurcated pipe first determines the bifurcation angle ω and the axis of each branch pipe based on the axis of the main pipe and the bifurcation point, and then designs the basic cones of the main and branch pipes. Determine the intersecting line, design the transition cones of the main and branch pipes, and finally design the reinforcing beam; by disassembling the symmetrical trifurcated beam bifurcated pipe in the form of components, it is beneficial to set a reasonable control for each component. The parameter system makes the adjustment of body shape parameters clear, and the influence chain of each parameter is shorter, which reduces the difficulty of design and does not require high experience for designers.

Description

technical field [0001] The invention belongs to the technical field of bifurcated pipes and their design, in particular to a symmetrical trifurcated beam type bifurcated pipe and a design method thereof. Background technique [0002] Bifurcated pipe is an important component used for diversion and confluence in the pressure water delivery system of hydropower station, and the symmetrical trifurcated beam bifurcated pipe is one of the most commonly used bifurcated pipes. like figure 1 As shown, the symmetrical trifurcated beam bifurcated pipe is mainly composed of the main pipe A, the first branch pipe B, the second branch pipe C, the third branch pipe D and the reinforcing beam E. It is a complex space curved thin-walled structure, usually composed of It is made of steel, and the intersecting lines of the tubes at the bifurcation part intersect at one point. The main pipe A, the first branch pipe B, the second branch pipe C and the third branch pipe D usually include a bas...
