1. Test Object

Spring testing machine: Mainly test the strength of various springs, elastic components and metal materials, and statistical records test data.

Electronic universal testing machine: Used for tensile, compression, bending, shearing and other mechanical properties tests of metal and non-metal materials.

2. Measurement results

Spring testing machine: is mainly used to measure the maximum deformation of the spring corresponding to the maximum force, or several deformation points of the spring corresponding to the force value, and the measurement of spring stiffness. It is mainly the relationship between deformation and force. It looks at the data of a whole spring.

Electronic universal testing machine: mainly measure the maximum tensile strength of materials, yield strength, elastic modulus and so on. It mainly measures the force and the corresponding force value in the case of some distance extension. It studies the data of a certain section of the sample.

3. Test method

Spring testing machine, as long as the test spring hanging hook (or placed on the pressure plate) set deformation can be measured spring force value (microcomputer control curve description and stiffness value calculation).

Electronic universal testing machine. After the sample is installed on the attachment, the original distance of the study is determined and the corresponding deformation measuring device is installed. After completing the test, look at the test curve, test results.

4. Calculation method

Spring testing machine in the test results, the impact of the machine itself in the software to do the corresponding compensation, the result is a true reflection of the spring.

Electronic universal testing machine because of the use of deformation measurement device (extensometer), so there is no host deformation compensation data in the software, if the measurement of spring, the measurement data is not accurate.
