The way that realizes at present the footwear shock-absorbing function mainly contains two classes.
A kind of is the performance damping that utilizes material for sole of shoe itself.Current way is that damping effect is realized in suitable position with possessing the prefabricated one-tenth beam of certain performance characteristic and be carried in sole, bipeltate pad for example, silicagel pad, foamed polyurethane mat, foaming EVA pad etc.There is cellular structure resin material inside after these foaming, in cellular hole, has been full of air.When being subject to external impacts, the outer wall of external force meeting extruding foaming material compresses the volume of the air in hole and air is discharged in atmosphere and goes, and this process has delayed time and displacement that impulsive force discharges, so can play the effect of bumper and absorbing shock.After impact disappears, the air pressure in hole is lower than atmospheric pressure on every side, and air can rapid reflux and be full of the hole of expanded material, and in cavity and after airborne air pressure formation balance, alveolate texture resiles, as shown in Figure 1.What this material damping modes was used is mostly resin material, quality softness own, and the sole contiguous sense is comparatively comfortable, so utilize the material damping more what use at present.But because this honeycomb characteristics that the character of various resin materials causes, cause after impacting disappearance, the complete restorable time of expanded material can be slower, and after bump, and alveolate texture is the easy damaged and recovery capability of infringement expanded material also.So it is soft but slow in reacting that the characteristics of material damping are contacts, and the life-span of beam is not long, after using certain hour, beam there will be the defect of soft couch and loses cushioning ability.
Another kind is commonly called structural damping, be to form the cavity volume of a sealing with resin material, and charge pressure surpasses an atmospheric gas in cavity.This kind of structure, when the chamber of cavity volume wall is subject to external shock, because gas in cavity volume can not leak, external force can cause chamber wall distortion the interior gas volume of compression square-cavity to decompose, to delay impulsive force, thus the function of the buffering of realization and damping.After impacting disappearance, compressed gas can expand rapidly and recover the shape of chamber wall.This structural damping mode has set in advance higher than atmospheric gas in the cavity volume of sealing because be, so the recovery process of cavity volume can be very fast after external force disappears, but because built-in air pressure is higher, in the situation that impulsive force is little, can feel harder as a ball sole that is full of gas with contacting of cavity volume, its comfort is poorer than the mode of previous materials damping.And, once, after the impaired gas leakage of chamber wall that resin forms, the cushioning ability that this structure forms will completely lose.
