Disc spring (disc spring) pressure testing machine is a high-precision equipment specifically used to test the mechanical properties of disc springs, such as stiffness, load displacement curve, fatigue life, etc. It is controlled by a microcomputer (computer) to achieve automated testing and data analysis.
1、 Normal working conditions of the equipment
Within the temperature range of 10 ℃ to 35 ℃, the relative humidity should not exceed 80%;
2. In a vibration free environment, there are no corrosive media or electromagnetic field interference around;
3. The fluctuation range of the power supply voltage should not exceed ± 10% of the rated voltage;
4. The host must be reliably grounded;
5. The electrical control part has good ventilation.
2、 Main testing content
Load displacement curve: measuring the stiffness (spring coefficient) of the disc spring
Ultimate compression: Maximum allowable deformation of the test disc spring
Deformation (relaxation rate): Evaluating plastic deformation after long-term compression
3、 Applicable standards
Domestic standards: DIN 2093, ISO 10243, ASTM F1566
International standard: GB/T 1972 (Technical specifications for disc springs)
