Product Description The vibration absorber is a type of equipment that converts mechanical vibrational kinetic energy into heat energy, which is then absorbed by the high elastic deformation properties of the rubber material.Its core functions include:Energy dissipation: It consumes vibrational energy by utilizing viscous shear and elastic hysteresis effects.Momentum isolation: It blocks the vibration transmission path, thereby reducing the risk of system resonance.Buffer protection: It absorbs shock loads and extends the service life of the equipment.Zhongmu Rubber is committed to developing both existing and new products, offering customers high-quality, high-performance isolation solutions.1.Typical construct type comparisonstructured typestructure characteristics Dynamic performance parametersapplication scenariosSolid compression typeSingle rubber column (no reinforced layer)Scirrhosity ShoreA70-90Low-frequency and large-amplitude industrial equipmentFiber enhancement typeRubber matrix + aramid fiber woven meshshear modulus≥15MPaEarthquake absorption of high-speed rail transitMetal nested typeAluminum alloy shell + rubber liningradial rigidity ≥500N/mmGenerator set vibration isolationMulti-layer compoundNBR base layer + EPDM damping layer + silicone surface layerthermal adaptability -50~+200oCSemiconductor equipment precision vibration isolation2.Classical structure and its classificationstructure typeoperational principletypical parameterapplication scenariosCompressed shock absorberThe rubber column is deformed by the axial compressionScirrhosity60-90 ShoreA,compression ratio≥30%Car suspension, machine tool shock absorptionCut-type shock absorberRubber sheets produce shear deformation under shear sheetsshear modulus≥10MPa,thickness2-5mmElectronic equipment, building vibration isolationCompound shock absorberRubber + spring / hydraulic pressure works togetherNonlinear stiffness characteristics, with adjustable dampingHeavy machinery, high-speed rail trackDamage linerThin-walled rubber sleeve covers the rotating shaftradial rigidity 50-500N/mm,friction(al) coefficient 0.1-0.3Rotary shaft frame vibration control3.Material type selection systemRubber typedynamic modulus (MPa)temperature range(-40oC~+150oC)oil resistivity (70#)Typical applicationNBR2-5-40oC~+120oCVolume change rate<10%Automobile shock absorber, hydraulic cylinder bushingEPDM3-8-50oC~+180oCVolume change rate<5%Building vibration isolation cushion, wind power sealingSBR2-4-20oC~+100oCVolume change rate<15%Industrial floor damping padIIR1-3-40oC~+80oCVolume change<8%Precision instrument vibration absorber4.International standard and test rangecriteriontest projecttechnical requirementISO 9001quality management systemWhole-process traceabilityGB/T 10179Experimental method of rubber shock absorberThe deformation was <20% after 10 ^ 6 cyclesASTM D3452Schematic drawing testRehome rate is> 70%IEC 60068-2-6Environmental experiments-40oC ~ + 85oC cycle aging5.Failure mode and structural improvementsfailure mode analysis of causes Improve the plansurface checking UV aging (> 2000h exposure)Add UV absorber (carbon black N330)The central hole collapsedLocalized overload (> 150% rated load)Set the safety factor (≥2.5)Damage recessionLiquid erosion (ASTM D471 test)HNBR oil resistant rubberInstall stress crackingTaper fitting (H7 / p6)Add flexible spacer (Shaw 30-50A)6.Typical application scenarios and product typesdevice typeApplication site vibration performance Type of shock absorberType of shock absorberexcavatorRotary turning platform and walking mechanismLow-frequency (2-10Hz) axial vibrationCompressed shock absorberHardness of Shore A 70-90, compression rate of 30%craneHanging arm, balance beamIntermediate frequency (10-50Hz) torsional vibrationCut-type shock absorberShear modulus of 15MPa, 5-8mm in thicknesscrane Hanging arm, balance beam Intermediate frequency (10-50Hz) torsional vibration Cut-type shock absorber Shear modulus of 15MPa, 5-8mm in thicknessloader Hanging arm, balance beam High-frequency (50-200Hz) random vibration Compound shock absorber Rubber + metal skeleton, with a damping ratio of ζ =0.8-0.9road roller Shbrator, self-walking wheel Impact load (5-10ms pulse) hydraulic buffer Ababsorbed energy 200 kJ with response time <50msshield tunneling machine Spindle drive, pipe segment assembly machine Multi-axial synchronous vibration (axial + radial) 3 D shock absorption module Flexible connection design, torsional torque 500 N·m7.Manufacturing Process Flow1.
