Static strength test mounting tool for suspension seat of rail car

Abstract

The invention provides a static strength test mounting tool for a suspension seat of a rail car. The static strength test mounting tool comprises left and right loading mechanisms, bolt and nut gaskets and a bottom plate; the bottom plate is formed by welding two pieces of transverse channel steel I to pieces of longitudinal channel steel II, and axial positioning long-strip-shaped holes are formed in an edge beam of each transverse channel steel I; each of the left and right loading mechanisms is composed of a bottom connecting piece with a positioning mounting holes, vertical channel steel III and a top mounting plate; and the bottom connecting piece is vertically welded to the bottom of the vertical steel channel III, the top of the vertical steel channel III vertically supports the topmounting plate, the vertical steel channel III and the top mounting plate form an inverted-L-shaped pull leg structure, and the spacing between L-shaped pull legs is adjusted to adaptively adjust theopening size between the left and right loading structures. Different opening sizes of the suspension seat is adjusted adaptively by means of a simple structure, the structure is simple, sufficient measuring points are provided, the reutilization rage of the tool is improved effectively, labor and material resources are saved, and the tool is more economical and more practical.

Description

technical field [0001] The invention belongs to the technical field of auxiliary tooling for physical measurement of railway vehicle testing, and in particular relates to a mounting tooling for static strength testing of rail vehicle suspension seats with a simplified structure and more sufficient measuring points. Background technique [0002] The static strength test of rail vehicle suspension seat, in actual application, must first consider that its static strength must meet the actual use requirements, use computer three-dimensional modeling and simulation, analyze the rail vehicle suspension seat through finite element, and simulate the rail vehicle vehicle in use The static load borne by the middle suspension seat, determine the maximum stress and maximum deformation allowed by the suspension seat under the condition of ensuring safety and durability, and judge whether the design of the suspension seat meets the design requirements, so as to test its design rationality,...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a mounting tool for the static strength test of the rail car suspension seat. Through the simplest structure, the mounting tool for the static strength test of the rail car suspension seat in the prior art needs to be specially customized, and the versatility is not enough. Ideal, low reuse rate, too complex structure, tool opening size cannot be adaptively adjusted according to different types of suspension seats, and static strength test tooling has limited measuring points and complex structure technical problems
