Introduction
→Permanent deformation test under vertical load of automobile leaf spring assembly: slow load of proof load, continuous load, unloading,camber height under static load, difference between twice camber height as permanent deformation.
→Used for leaf spring stiffness test: slow loading,continuous loading, step loading, 1.5 times full load, elastic deformation, stiffness, elastic deformation at specific load, loading deformation at specific load, unloading deformation at specific load, etc.
→Used for load control, displacement control, deformation control, compression load, deformation or residual height, camber height under static load, stiffness, real-time stiffness curve (Load-Deformation curve, Load-Displacement curve, Time-Deformation curve), set load test, set deformation test, cyclic test.
→The camber height deviation of leaf spring assembly under static load ≤±6mm, camber height deviation of heavy-duty automobile ≤±8mm.
→Stiffness deviation of leaf spring assembly: if stiffness ≤93.2N/mm, deviation ±7%. if stiffness >93.2N/mm, deviation ±10%.
