The invention provides a manufacturing method and device of a fatigue-resistant composite frog. The manufacturing method comprises; establishing a frog solid model and a wheel set solid model; performing finite element mesh division on the frog solid model and the wheel set solid model to obtain the frog solid model and the wheel set solid model subjected to finite element mesh division; setting apreset mechanical parameter set for the frog entity model and the wheel set entity model subjected to finite element mesh division, and obtaining a finite element model set; carrying out finite element dynamic force analysis on the finite element model group under a preset constraint condition to obtain a stress envelope line of the frog entity model; manufacturing a frog based on the frog solidmodel, and cutting the frog according to the stress envelope line of the frog solid model to obtain a to-be-supplemented frog; and supplementing the to-be-supplemented frog by using a high-strength alloy material through a 3D printing technology to obtain the composite frog.
Description
technical field [0001] The present application relates to the field of rail manufacturing, and in particular, to a method and device for manufacturing a fatigue-resistant composite frog. Background technique [0002] With the rapid development of the railway industry, the demand for the speed of railway transportation is also increasing, and the accompanying problem is that the requirements for the strength of the rails are also increasing. [0003] For the frog part in the rail, in the prior art, frogs made of high-strength materials are mostly used for replacement, such as frogs made of bainite. However, the manufacturing cost of high-strength materials is high. In practice, only frogs are used in The section that is relatively more prone to metal fatigue has been replaced. How to improve the strength of all frogs under the premise of reducing costs has become a difficult problem in the field of rail manufacturing. SUMMARY OF THE INVENTION [0004] In view of this, the ...
