Leaf Spring Compression Stiffness Testing Machine
Product Description:
The leaf spring compression stiffness testing machine is mainly suitable for testing the compression stiffness, compression force, compression load, permanent deformation, compression deformation, bearing deformation and bearing capacity performance of locomotive leaf springs.
Technical Parameter:
Compression load test force: 50kN
Effective measurement range of compression load: 2%-100%
Repeatability error of compression force indication: 2%-100%
Minimum reading value of compression force: ±0.05%
Minimum reading value of compression displacement: 0.01mm
Loading force measurement method: electronic loading
Displacement detection accuracy: (50+0.30l) μm
Test stroke: 500mm
Locomotive Leaf Spring Specifications:
Multi-leaf spring: It consists of multiple steel sheets with different lengths and the same width. The steel plates of multiple leaf springs are superimposed into an inverted triangle shape. The uppermost steel plate is the longest, and the lowermost steel plate is the shortest. The more steel plates, the thicker and shorter, the greater the spring rigidity.
Few leaf springs: superimposed by steel sheets with thin ends and thick middle, equal width and equal length.
Compared with the multi-leaf spring, the less-leaf spring is about 50% lighter than the multi-leaf spring under the same stiffness (that is, the same load capacity), which reduces fuel consumption and increases driving comfort. Moreover, the single leaf of the few leaf springs are in point contact, which reduces relative friction and vibration and increases the comfort of passengers.
