Product Description:

The locomotive suspension spring lateral stiffness testing machine is mainly suitable for the comprehensive performance testing of locomotive suspension springs such as compression stiffness, elastic stiffness, load stiffness, pressure stiffness, and deformation stiffness.

Suspension Spring Stiffness Requirements:

The stiffness of the suspension spring of a locomotive is the ratio of the unit working load F to the unit deformation f. The tolerance of the suspension spring stiffness is ±KF. When the suspension spring stiffness is to be assessed, the working deformation must be 30%-70% of the full deformation.

Technical Parameter:
Specification: ZCTL-300kN
Structure: Microcomputer controlled automatic gate type double screw structure
Working mode: ball screw drive, precision motor loading
Display mode: large LCD, Chinese characters display
Data processing: automatic collection, processing, save, query, and print
Effective measuring range: 1%-100%FS
Test force resolution: 0.1N
Relative error of zero point: ±0.1%
Relative error of test force indication: ±1.0%
Relative error of test force indication repeatability: 1.0%
Displacement resolution: 0.01mm
Error of displacement indication (μm): ≤±(50+0.15l)
Stretching space: 300mm
Compressed space: 300mm
Pressure plate diameter: 120mm
Parallelism of upper and lower platens: ≤0.05mm
Speed range: 1-500mm/min
