Description

Technical Field

[0001] The invention relates to the technical field of mechanical strength, in particular to a multi-field coupling mechanical strength tester and a testing method thereof. Background Art

[0002] Multi-field coupling is the interaction under multiple conditions. Multiple fields include the interaction of temperature field, stress field, humidity field and other fields. The performance test of materials under multiple fields is an important method to study the performance of materials. Multi-field coupling mechanical strength tester is an instrument for testing the mechanical properties of materials under the interaction of multiple field conditions.

[0003] The defects of existing mechanical strength testers are:

[0004] 1. Prior art US6050149A discloses a device for measuring the bending strength of a sheet material. The technology provides a device for measuring the natural bending strength of a sheet material and the bending strength of a folded or scored portion of a sheet material and for dynamically analyzing the test results. The device can only perform bending strength tests, and cannot perform various strength tests such as indentation and torsion of materials under various temperature conditions. Therefore, a multi-field coupled mechanical strength tester that can perform various mechanical strength tests at different temperatures is needed to solve this problem.

[0005] 2. The prior art KR101736145B1 discloses a tensile strength tester. The tensile strength of the steel wire test of this technology can measure the tensile force of the conductor while maintaining the stretched state. The device cannot test the mechanical properties at different temperatures. If the product is heated externally, the heat in the product is easily lost, resulting in thermal instability and easy heat waste. Therefore, a multi-field coupled mechanical strength tester that can perform mechanical strength tests at different temperatures and reduce heat waste is needed to solve this problem.

[0006] 3. The prior art KR101743406B1 discloses a strength testing device, which can apply a shear force to the first building material; and a driving part is connected to the through-part and causes the through-part to rotate, wherein the second building material is injected into the through-part, and the friction angle between the first building material and the second building material can be measured. When the device is used to test a product, if the product generates debris and impurities, when the debris is cleaned, if there is internal heating causing heat inside the device, heat loss is easily caused when cleaning the impurities. Therefore, a multi-field coupled mechanical strength tester that can easily clean internal impurities and has less heat loss is needed to solve this problem.

[0007] 4. Prior art CN103512803B discloses an in-situ testing instrument for the micromechanical properties of materials with multiple loads and multiple physical fields coupled. The combination of multi-load loading and multi-physical field coupled loading in this technology can more realistically simulate the actual working conditions of the workpiece material, and provide effective means and methods for testing the micromechanical properties of materials under conditions close to service. The equipment cannot automatically remove the product after the product test is completed. When the product heat is high, it is dangerous to manually remove the product. Therefore, a multi-field coupled mechanical strength tester that can automatically remove the product and reduce the product temperature is needed to solve this problem. Summary of the invention
