1. Measure the corresponding force value F to determine whether the spring is qualified by means of the deformation of the spring, or pressure to height H.
2. By the force value F of the spring, the corresponding spring deformation is measured, and H or height H is used to determine whether the spring is qualified.
3. A little or more test can be conducted to determine whether the spring is qualified.
4. It can be measured in sections and can calculate the stiffness (elastic coefficient) K and average stiffness of each segment.
5. Sample inspection can be carried out for the product, and batch test can also be conducted (there are batch test equipment in mechanical part).
Large manual for all kinds of cylindrical spring spring tension and compression testing machine, disc spring, spring, spring, leaf spring, special-shaped spring precision spring tension, stress, displacement, stiffness and precision testing and analysis.
The spring tension testing machine described below is based on the mechanical industry standard of the People's Republic of China:
JB/T 7796-1995, JB/T 7796-2005 "test method for spring tension testing machine"
JIS b7738-2001 "compression and stretch disc spring testing machine" provides technical requirements for production.
1, to determine whether the spring is qualified by measuring the corresponding force value F by measuring the deformation of the spring H or H.
2, through the spring force value F, to measure the corresponding spring deformation H or height H to determine whether the spring is qualified.
3, one or more tests can be carried out to determine whether the spring is qualified.
4, it can be measured piecewise, and can calculate the stiffness (elastic coefficient) K and average stiffness of each segment.
5, sampling inspection for products, batch testing can also be carried out (mechanical parts have batch test device).
