The tennis deformation testing machine is suitable for testing the thrust deformation and recovery deformation of tennis balls. This machine is also known as tennis deformation tester, tennis deformation tester, tennis compression tester, tennis pressure deformation tester, tennis compression tester, tennis deformation tester, tennis deformation tester

Tennis deformation testing machine execution standard:

Meet the relevant standards and customer requirements of GB/T22754-2008, QB/T1510-1992 Tennis 5.6

Principle of tennis deformation testing machine:

The tennis ball is placed between the test boards, and the test parameters are set: initial force, loading force, loading time, loading displacement, etc. The automatic test displays the test results of advancing deformation and restoring deformation

Functional characteristics of tennis deformation testing machine:

1. The touch screen display displays real-time force values, displacement deformations, and automatically saves data; The display interface can display the test curve in real time; Test real-time parameters such as speed and deformation.

2. Using a high-precision, fully digital speed control system and precision reducer, the precision screw pair is driven for testing, achieving a wide range of adjustment of the test speed and smooth operation.

3. Adopting high-precision sensors and professional measurement and control software, with high testing accuracy, wide testing range, and simple operation.

4. Standard micro printer, capable of printing results at any time

5. At the end of the experimental process, provide the measurement results of the deformation values. The process is time-saving and labor-saving, reducing the interference of subjective factors and effectively improving the reliability of testing.
