Description

[0001] DESCRIPTION

[0002] A drop weight impact test device that allows angled impact testing

[0003] Field of the Invention

[0004] The invention generally relates to devices that enable drop weight impact testing. The invention particularly relates to the impact testing device apparatus, which is used to examine the mechanical behavior of materials exposed to impact, enabling the measurement of the resistance and absorption energy of the material against an angled impact, which enables the materials to be rotated at the desired angle and thus the material to be impacted at the desired angle.

[0005] State of the Art

[0006] Nowadays, it is necessary to measure the resistance of materials such as metal, polymer, composite, etc., to various impacts that they will be exposed to during their use, and the energy to absorb the impact. This energy is used to determine the toughness, impact strength, impact resistance, or fracture resistance of the material, depending on the test performed and the property being measured. Impact test devices are used for this measurement.

[0007] In the impact test devices used in the current technique, the material specimen to be tested is placed in the test device as a flat plate. The striker in the impact test device impacts the center of the plate in the vertical direction.

[0008] The test is performed only for impacts perpendicular to the specimen surface. However, in practice, the impact angle on the material may vary. As a result, the material's absorption energy and mechanical behavior under impact may change. In continuous fiber-reinforced composites, impact angle variation significantly affects test results. In these composites, the fiber is the primary load-bearing component. The reaction force in the material also varies with the fiber orientation angle. Thus, impact test devices using the current technique do not always provide results in the intended direction for every material and yield limited outcomes. Research into these limitations identifies relevant documents. Document TR2011 / 10843 discusses a pendulum-type impact test device with bending control. This device operates on the weight drop principle. Nevertheless, the force in this device is applied perpendicularly to the material surface, leading to the same limitations as the current technique.

[0009] The document numbered CN219475252U is related to a vertical impact test device. In this document, a mechanism consisting of a vertically moving hammer carrier and a vertically moving plate carrier is explained in the test device mentioned in this document to check the strength of fiber cement plates. The hammer head mentioned here is fixed to an electromagnetic bearing. The aim of the mentioned configuration is for the hammer head to produce a second impact after impacting the plate. However, this document does not mention any information that enables the application of force to the plate at an angle. As a result, improvements are being made regarding impact testing devices; therefore, new structures are needed that will eliminate the disadvantages mentioned above and provide solutions to existing systems.

[0010] Aim of the Invention

[0011] The present invention relates to an impact tester apparatus that meets the above- mentioned requirements, eliminates all disadvantages, and brings some additional advantages. The main purpose of the invention is to adjust the angle of the material on which the weight falls in drop weight impact testers. In this way, the resistance of the material against impacts at different angles and the absorption of energy are measured.

[0012] One purpose of the invention is to present an apparatus that can be applied to all kinds of impact testers that can operate vertically.

[0013] In order to realize all the advantages mentioned above and that will be understood from the detailed explanation below, the present invention is an impact tester apparatus that allows the workpiece to be positioned at the desired angle in order to examine the mechanical behavior of the workpiece against the angled loads that will come on it, used in drop weight impact testers that operate vertically; • a top plate, which is the carrier case of the apparatus and serves as a centering device for the impact tester, with a weight opening through which the weight that will fall on the workpiece will pass,

[0014] • two side plates, which are the carrier case of the apparatus and are positioned oppositely in a way that they are connected to the top plate,

[0015] • two first axis movement plates, which are connected between the side plates with a single axis center so that they rotate around a first axis and provide movement of the workpiece around this axis, parallel to the side plates and positioned oppositely to each other,

[0016] • two second axis fixing plates, which are connected between the first axis fixing plates with a single axis center so that they rotate around a second axis and provide movement of the workpiece around this axis, parallel to the second axis fixing plates and positioned oppositely to each other,

[0017] • a holder plate, which is positioned between the second axis movement plates by connecting to the second axis movement plates, and on which the workpiece is positioned, is obtained.
