[0033] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0034] refer to Figures 1-4 This application provides a heated abrasion resistance testing machine, including a body 100, a placement plate 200, a first testing component 300, and a driving component (not shown).

[0035] The main body 100 refers to the main structure that carries the various functional modules. Specifically, it can be implemented using a metal frame in conjunction with a control panel to provide mechanical support and an operating interface for the equipment.

[0036] The placement plate 200 is connected to the bottom of the machine body 100 and is used to place the object to be tested. The placement plate 200 refers to the platform that supports the object to be tested, and can be implemented using a steel plate with clamps to ensure that the object to be tested does not shift during the test.

[0037] The first test component 300 is located above the placement plate 200. The first test component 300 includes a first support member 310 and a heating element 320. The first end of the first support member 310 is movably mounted on the body 100, and the heating element 320 is mounted on the second end of the first support member 310. The heating element 320 is used to contact the object under test and heat it. The first test component 300 refers to a composite test unit that performs heating and friction. Specifically, it can be implemented using a cantilever structure with a linear guide rail. One end of the support member is connected to the drive component, and the other end is equipped with the heating element 320. The heating element 320 is a contact component with temperature control function. Specifically, it can be implemented using a resistance heating element in conjunction with a heat-conducting metal head, transferring heat to the surface of the object under test through conduction.

[0038] The drive component is located inside the body 100 and is connected to the first end of the first support member 310 to drive the first test member 300 to reciprocate. The drive component refers to the power device that generates reciprocating linear motion, which can be implemented by using a servo motor in conjunction with a ball screw mechanism to precisely control the movement speed and stroke of the test member.

[0039] Specifically, after the object under test is fixed on the placement plate 200, the driving component pushes the first support member 310 to move along a predetermined trajectory, causing the heating element 320 to contact the surface of the object under test with a set pressure. The heating element 320 generates heat when energized, and this heat is conducted to the surface material of the object under test through continuous contact. Simultaneously, the driving component maintains the reciprocating motion of the first support member 310, causing the heating element 320 to form a periodic friction trajectory on the surface of the object under test. During this process, heat transfer and mechanical friction act simultaneously on the object under test, simulating the actual working condition of materials undergoing continuous friction at high temperatures.

[0040] This application effectively simulates the friction and wear process of airport runways under high-temperature environments, overcoming the technical shortcomings of traditional equipment where testing conditions do not match actual working conditions. By simultaneously applying heat and mechanical friction, the wear resistance of materials under thermo-mechanical coupling can be accurately evaluated, providing more reliable test data for the research and development of runway surface materials. The adjustability of temperature parameters during testing expands the application range of the equipment, enabling it to adapt to testing needs under different environmental temperature conditions.

[0041] The heating element 320 includes a heating body 321 and a friction head 322. The heating body 321 is located on the second end of the first support member 310, and the friction head 322 is detachably connected to the heating body 321. The heating body 321 is the component used to generate heat, which can convert electrical energy into thermal energy to heat the object being tested. The friction head 322 is the contact component that directly contacts the object being tested; it can be made of metal or ceramic materials, and its surface can be designed with a specific shape to simulate actual friction scenarios. The detachable connection between the friction head 322 and the heating body 321 refers to the mechanical connection method that allows the friction head 322 to be separated from the heating body 321. This can be achieved using a threaded fit, a snap-fit ​​structure, or a plug-in design, facilitating the replacement of different types of friction heads 322 according to testing requirements.

[0042] Specifically, the heating body 321 is fixed to the second end of the first support member 310 and connected to an external power source via a wire to obtain electrical energy. The friction head 322 is detachably connected to the end of the heating body 321 and can be removed from the heating body 321 when the type of the friction head 322 needs to be adjusted or maintenance is required. During the test, the heating body 321 continuously provides heat to maintain the set temperature of the friction head 322, while the driving component moves the first support member 310, causing the friction head 322 to contact the surface of the object being tested and reciprocate in friction.

[0043] In one embodiment, the friction head 322 is provided with a plurality of petal-shaped protrusions 323, which are circumferentially spaced around the axis of the heating body 321. The petal-shaped protrusions 323 refer to protrusions with a petal-like shape. This petal-shaped design increases the contact area between the friction head 322 and the object being measured, while also dispersing localized stress. The plurality of petal-shaped protrusions 323 are evenly arranged along the circumferential direction of the axis of the heating body 321, specifically using an equiangularly spaced layout, so that the friction head 322 forms a continuous and uniform frictional action with the object being measured during rotation or movement.

[0044] Specifically, the friction head 322 contacts the surface of the object under test through petal-shaped protrusions 323. When the driving component drives the first test component 300 to move back and forth, the structure of multiple petal-shaped protrusions 323 distributed around the axis of the heating body 321 allows the friction head 322 to cover a wider friction area during movement. During the heating process of the heating element 320 heating the surface of the object under test, the sharp edges of the petal-shaped protrusions 323 can enhance the shear force during the friction process, while the circumferentially spaced distribution avoids the concentration of frictional resistance due to excessive density of protrusions, thus more realistically simulating the complex working conditions of the surface of the object under test under high temperature environment.

[0045] The first test component 300 also includes a fastener 330. The second end of the first support member 310 has a mounting hole 311. The first end of the heating body 321 is inserted into the mounting hole 311, and the second end of the heating body 321 is used to connect to an external power source. A portion of the friction head 322 is inserted into the mounting hole 311 and contacts the first end of the heating body 321. The fastener 330 is threadedly connected to the first support member 310, and abuts against the friction head 322. Specifically, the heating body 321 is initially positioned by inserting its first end into the mounting hole 311. After the friction head 322 is partially inserted into the mounting hole 311, it forms a conductive contact with the heating body 321. After the fastener 330 is screwed into the threaded hole of the first support member 310, its end presses against the outer surface of the friction head 322. The axial pressure generated by tightening the thread keeps the friction head 322 in close contact with the heating body 321. This structure ensures electrical conductivity stability while allowing for quick replacement of the friction head 322 by loosening the fastener 330.

[0046] In this embodiment, the heating element 321 is a soldering iron. A soldering iron is a tool that converts electrical energy into heat energy. Specifically, it can be a portable structure with a replaceable heating element. Its front end is the heat-conducting end that contacts the object being tested, and its rear end is the power connection end. When the driving component moves the first support member 310, the heat-conducting end of the soldering iron contacts the surface of the object being tested. Current causes the resistance wire to heat up, transferring the heat to the friction head 322. This allows for continuous heating of the object's surface during friction, for example, allowing friction testing of airport runway surface materials at a set temperature, thus more realistically simulating the frictional wear of rubber layers under high-temperature conditions.

[0047] The heating element 320 also includes a temperature adjustment switch 324, which is located on the heating body 321 and used to control the heating temperature of the heating body 321. The temperature adjustment switch 324 and the heating body 321 are connected by wires to form a closed circuit. When the operator rotates the knob of the temperature adjustment switch 324 or inputs a target temperature value, a control signal is transmitted to the power supply circuit of the heating body 321, thereby adjusting the input power. For example, when it is necessary to simulate a friction test under high temperature conditions, the heating power can be increased by rotating the knob clockwise, raising the surface temperature of the heating body 321 to the set value; when it is necessary to lower the test temperature, the power output can be reduced by rotating the knob counterclockwise. This adjustment process allows the heating temperature to be dynamically changed during the test to adapt to the heat resistance test requirements of different materials. For example, the temperature of the heating body 321 can be controlled within the range of 50°C to 300°C, thereby realistically replicating the friction loss process of the rubber layer under high temperature conditions.

[0048] The first support member 310 includes a first support plate 312, a second support plate 313, a third support plate 314, and an adjustment knob 315. The first end of the first support plate 312 extends into the machine body 100 and connects to the drive component. The second support plate 313 is located on the second end of the first support plate 312 and has a slotted hole 313a. The first end of the adjustment knob 315 is located on one side of the second support plate 313, and the third support plate 314 is located on the other side of the second support plate 313. The second end of the adjustment knob 315 passes through the slotted hole 313a and is threadedly connected to the first end of the third support plate 314. The heating element 320 is located on the second end of the third support plate 314. Specifically, when it is necessary to adjust the contact position between the heating element 320 and the object being measured, rotating the adjustment knob 315 causes its threaded rod to move axially, driving the third support plate 314 to slide along the slotted hole 313a of the second support plate 313. The length of the slot 313a limits the adjustment range, and the precision of the threaded connection ensures the stability of displacement control. This structure allows for independent adjustment of the lateral position of the heating element 320 while the drive component maintains a fixed stroke, thus adapting to the testing needs of objects of different sizes.

[0049] The heated abrasion resistance testing machine also includes a second testing component 400, located above the placement plate 200. The second testing component 400 includes a second support member 410 and a friction rod 420. The first end of the second support member 410 is movably mounted on the machine body 100, and the friction rod 420 is mounted on the second end of the second support member 410. A driving component is connected to the first end of the second support member 410 to drive the second testing component 400 in reciprocating motion. The second testing component 400 is a modular structure used to perform conventional friction tests in addition to heated tests. Specifically, it can be implemented using a support assembly with a detachable friction rod 420, forming a complementary testing mechanism with the first testing component 300. The second support member 410 is a rigid component that supports the friction rod 420 and enables linear movement. Specifically, it can be implemented using a metal bracket with a slide rail, and the friction stroke is controlled by adjusting the range of motion. Friction rod 420 refers to a friction element that directly contacts the surface of the object being measured. Specifically, it can be implemented using an alloy rod with a regular texture on the surface. By changing the friction rod 420 of different materials, diverse friction conditions can be simulated.

[0050] Specifically, the second test component 400 drives the second support component 410 to reciprocate horizontally via a drive component, causing the friction rod 420 to slide on the surface of the object under test on the placement plate 200 at a preset speed. When a conventional friction test is required, the second test component 400 operates independently; when a heated friction test is required, the first test component 300 and the second test component 400 can operate in concert.

[0051] The machine body 100 is equipped with a counter 110, a speed display 120, a power switch 130, and an indicator light 140. Both the counter 110 and the speed display 120 are connected to the drive component. The counter 110 records the number of reciprocations of the first test component 300 and the second test component 400, while the speed display 120 displays the moving speed of the first test component 300 and the second test component 400. The power switch 130 is connected to the drive component and the heating element 320, and the indicator light 140 displays the working status of the drive component. Specifically, when the drive component moves the first test component 300 and the second test component 400 in reciprocating motion, the counter 110 automatically accumulates the number of movements and stores the data by receiving pulse signals from the drive component. Simultaneously, the speed sensor collects the rotational speed information of the drive component in real time, and after signal processing, the speed display 120 presents the moving speed in numerical form. During the test, the operator can judge the test progress by observing the number of reciprocations recorded by the counter 110 and adjust the operating parameters of the drive component in conjunction with the speed display 120 to ensure that the test conditions meet the preset standards.

[0052] When the power switch 130 is closed, the drive component and the heating element 320 are simultaneously powered on and started. The drive component drives the first test component 300 in a reciprocating frictional motion, while the heating element 320 heats the surface of the object being tested. The indicator light 140 collects the current changes of the drive component through circuit signals. When the drive component is operating normally, it displays a green light; when it stops, it is off; and when an abnormality occurs, it switches to a flashing red light. Operators can monitor the equipment's operating status by observing the color changes of the indicator light 140. This system achieves centralized control of the equipment's power supply system and intuitive display of its operating status, solving the problems of complex operation and safety hazards associated with traditional equipment, and effectively improving the safety and ease of operation of the testing process.
