Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical analysis equipment, specifically relating to an internal force analyzer for engineering components. Background Technology
[0002] Internal forces in engineering components typically refer to bending moment and torque during bending and torsion, shear force during shearing, and axial force during tension and compression.
[0003] Currently, engineering components are typically simulated using models that undergo torsion, bending, tension, compression, or shearing to induce deformation for display and analysis. However, existing engineering component models struggle to display torsion angles, and bending strain is not intuitive enough. Utility Model Content
[0004] This invention provides an internal force analyzer for engineering components, aiming to solve the technical problems that existing engineering component models are difficult to display torsional angles and whose bending strain is not intuitive enough.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an internal force analyzer for engineering components, comprising:
[0006] The spindle is a flexible shaft;
[0007] Multiple component modules are sequentially fitted onto the mandrel and pressed against each other to form an engineering component model. The component modules slide and rotate with the mandrel.
[0008] At least one of the two adjacent component modules has angle scale stripes on its outer peripheral surface and pointer stripes on its outer peripheral surface, or one has angle scale stripes on its axial end surface and the other has pointer stripes on its axial end surface; each component module has grid stripes on its outer peripheral surface.
[0009] In one possible implementation of the engineering component internal force analyzer provided by this utility model, the angle scale stripes, the pointer stripes, and the grid stripes are raised or recessed.
[0010] In one possible implementation of the engineering component internal force analyzer provided by this utility model, the component module is cylindrical, coaxially arranged with the mandrel, sleeved on the mandrel, and has the degree of freedom to slide along the axial direction of the mandrel.
[0011] In one possible implementation of the engineering component internal force analyzer provided by this utility model, the angle scale stripes and the pointer stripes are respectively disposed on the outer peripheral surfaces of two adjacent component modules.
[0012] In one possible implementation of the engineering component internal force analyzer provided by this utility model, the mandrel includes a first half-shaft, a second half-shaft, and a telescopic unit. The first half-shaft and the second half-shaft are coaxially arranged with the same diameter. A plurality of the component modules are sleeved on both the first half-shaft and the second half-shaft. The telescopic unit is connected to the first half-shaft and the second half-shaft and is used to move the first half-shaft and the second half-shaft closer to each other or further away from each other by telescoping.
[0013] In one possible implementation of the engineering component internal force analyzer provided by this utility model, the telescopic unit includes a slide rod, which is fixedly connected to one end of the first half-shaft facing the second half-shaft. A sliding groove is provided at one end of the second half-shaft facing the first half-shaft, and the slide rod slides in cooperation with the sliding groove.
[0014] The beneficial effects of the engineering component internal force analyzer provided by this utility model are as follows: Compared with the prior art, the engineering component internal force analyzer provided by this utility model has angle scale stripes and pointer stripes on the outer peripheral surface or axial end surface of two adjacent component modules, respectively. When one of the component modules is twisted to simulate the torsion of the engineering component under torque, the component module with pointer stripes will rotate at an angle relative to the component module with angle scale stripes, and the pointer stripes will point to the position of the angle scale stripes, intuitively displaying the torsion angle, and thus intuitively displaying the torsional strain. Since the component modules have the degree of freedom to move along the mandrel, when a bending moment is applied to at least two component modules to simulate the bending of the engineering component, the component modules will flip outwards, and the outer parts will move away from each other, thus intuitively displaying the bending strain.

The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0024] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0027] Existing engineering component models are typically monolithic, such as a single cylindrical or rectangular structure, with meshes on the sides. These models are displayed by showing the deformation of the mesh during bending, torsion, and stretching, including bending strain, torsional strain, and tensile strain. However, the applicant has discovered at least the following problems during use:
[0028] 1. It is difficult to intuitively obtain the angle of twist during the twisting process;
[0029] 2. When bending, the bending strain is only shown by the deformation of the mesh, but the deformation of the mesh is small. Therefore, the bending strain is not intuitive enough.
[0030] Please refer to the following: Figures 1 to 2The internal force analyzer for engineering components provided by this utility model will now be described. The internal force analyzer for engineering components includes a mandrel and multiple component modules 20; the mandrel is an elastic shaft, and the multiple component modules 20 are sequentially sleeved on the mandrel and pressed against each other to form an engineering component model. The component modules 20 slide and rotate with the mandrel; at least one of two adjacent component modules 20 has angle scale stripes 41 on its outer peripheral surface and pointer stripes 42 on its outer peripheral surface, or one of them has angle scale stripes 41 on its axial end surface and the other has pointer stripes 42 on its axial end surface; each component module 20 has grid stripes 33 on its outer peripheral surface.
[0031] It should be noted that both the mandrel and component module 20 are made of materials with a certain degree of elasticity, such as polyurethane, rubber, and silicone, to produce a certain deformation when subjected to pressure or bending, demonstrating compressive strain and bending strain. When the angle scale stripes 31 and pointer stripes 32 are provided on the outer peripheral surface, there is no requirement for the transparency of the component module 20; when the angle scale stripes 31 and pointer stripes 32 are provided on the axial end face, the component module 20 with the angle scale stripes 31 and pointer stripes 32 can be a semi-transparent or transparent module, as long as the angle scale stripes 31 and pointer stripes 32 are visible.
[0032] The method of using the internal force analyzer for engineering components provided in this embodiment of the invention is as follows:
[0033] When it is necessary to analyze the internal forces of an engineering component under torsion, one of the component modules 20 with angle scale stripes 31 and pointer stripes 32 is torn. The component module 20 with pointer stripes 32 will rotate at an angle relative to the component module 20 with angle scale stripes 31, and the pointer stripes 32 will point to the position of the angle scale stripes 31, thus intuitively displaying the torsion angle and torsional strain.
[0034] When it is necessary to analyze the internal forces of an engineering component during bending, the mandrel is bent downwards. The component module 20 will flip outwards with the lower side as the axis, so that the upper sides of adjacent component modules 20 are separated and moved away from each other, thus showing the bending strain. This is more intuitive than simply showing the bending strain through the deformation of the model.
[0035] The beneficial effects of the engineering component internal force analyzer provided by this utility model are as follows: Compared with the prior art, the engineering component internal force analyzer provided by this utility model has angle scale stripes 31 and pointer stripes 32 respectively on the outer peripheral surface or axial end surface of two adjacent component modules 20. When one of the component modules 20 is twisted to simulate the torsion of the engineering component under torque, the component module 20 with pointer stripes 32 will rotate at an angle relative to the component module 20 with angle scale stripes 31, and the pointer stripes 32 will point to the position of the angle scale stripes 31, intuitively displaying the torsion angle, and thus intuitively displaying the torsional strain. Since the component module 20 has the degree of freedom to move along the mandrel, when a bending moment is applied to at least two component modules 20 to simulate the bending of the engineering component, the component modules 20 will flip outward, and the outer parts will move away from each other, thus intuitively displaying the bending strain.
[0036] like Figure 1 and Figure 2 As shown, in a specific embodiment of the engineering component internal force analyzer provided in this utility model, the angle scale stripes 31, pointer stripes 32 and grid stripes 33 are raised or recessed.
[0037] Furthermore, the angle scale stripes 31, pointer stripes 32, displacement scale stripes, and grid stripes 33 are painted with different colors than the component module 20 for easier viewing.
[0038] The angle scale stripes 31 consist of multiple equally spaced short lines, with a fixed angle of 2 degrees between adjacent short lines. It can also be 1 degree or 5 degrees, depending on the actual needs.
[0039] The pointer stripe 32 is a short line pointing to the angle scale stripe 31.
[0040] The grid stripe pattern 33 is a rectangular grid to make the strain more intuitive.
[0041] like Figure 1 and Figure 2 As shown, in a specific embodiment of the engineering component internal force analyzer provided in this utility model, the component module 20 is cylindrical, coaxially arranged with the mandrel, sleeved on the mandrel, and has the degree of freedom to slide along the mandrel axial direction.
[0042] Furthermore, the angle scale stripes 31 and the pointer stripes 32 are respectively provided on the outer peripheral surfaces of two adjacent component modules 20 to facilitate the viewing of the torsion angle.
[0043] like Figure 1 and Figure 2As shown, in a specific embodiment of the engineering component internal force analyzer provided in this utility model, the spindle includes a first half-shaft 11, a second half-shaft 12 and a telescopic unit. The first half-shaft 11 and the second half-shaft 12 are coaxially arranged with the same diameter. A plurality of component modules 20 are sleeved on the first half-shaft 11 and the second half-shaft 12. The telescopic unit is connected to the first half-shaft 11 and the second half-shaft 12 and is used to move the first half-shaft 11 and the second half-shaft 12 closer to each other or further away from each other by telescopic movement.
[0044] Specifically, in one embodiment of the engineering component internal force analyzer provided in this utility model, the telescopic unit includes a slide rod 13, which is fixedly connected to one end of the first half-shaft 11 facing the second half-shaft 12. The second half-shaft 12 has a sliding groove at one end facing the first half-shaft 11, and the slide rod 13 slides in cooperation with the sliding groove.
[0045] Specifically, the slide bar 13 can be fully placed in the slide groove, so that the first half-shaft 11 and the second half-shaft 12 can fit tightly together to form a complete shaft.
[0046] It should be noted that the applicant also found that when demonstrating tension, the engineering component model had low elasticity and it was difficult to generate significant strain.
[0047] Therefore, the mandrel is configured as a first half-shaft 11, a second half-shaft 12, and a slide rod 13. The second half-shaft 12 is connected to the slide rod 13 to normally demonstrate bending strain. When it is necessary to analyze the internal force of the engineering component under tension, a tensile force is applied to the first half-shaft 11 and the second half-shaft 12 to simulate the tensile condition of the engineering component. The slide rod 13, which is fixedly connected to the first half-shaft 11, slides outward, and the distance between the two component modules 20 at the ends of the first half-shaft 11 and the second half-shaft 12 increases, thereby intuitively simulating and demonstrating the tensile strain of the engineering component.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
