Principle of work:
Vibration isolation efficiency: according to conservation of energy principle, extraneous vibrational energy can be converted into heat by the damping action of rubber oiling cushion blocking, is delivered to hard disk again after the vibrational energy decay.Frequency with extraneous vibrational energy is come subregion, is being lower than vibrating isolation system natural frequency place in vibration frequency, is the rigidity of spring to what vibration isolating effect played a major role, claims rigidity control again, and the choose reasonable spring rate can effectively suppress vibration and amplify.At the resonant frequency place, influence the quality that resonance amplitude is enlarged into vibrating isolation system, be called quality control.After having spent resonance zone, mainly the nonlinear interaction by the damping oil sac comes the attenuation by absorption vibrational energy.So do the natural frequency of vibrating isolation system low more, in the time of resonance enlargement factor control low more, the vibration isolating effect of this system runs off look.Physical parameter by regulating spring and oiling cushion blocking can obtain optimum vibration isolating effect.
Pooling feature: the system of low natural frequency needs very big displacement to keep the elastic movement of system down excited by impact, otherwise rigid collision takes place owing to displacement is not enough, therefore after the limit of having measured vibration displacement under the common vehicle-mounted condition, additional one can be satisfied the buffering requirement greater than this limit and buffering stop block that rigidity is bigger.When hard-disk cartridge generation dropping shock, snubber assembly is delivered to hard disk after can allowing impulsive force decay to a certain degree again.
Heating function: in the PCB printed board, be connected with power supply, and dispose a temperature sensor, when environment temperature is lower than setting value, for example 5 degrees centigrade, this is the working temperature lower limit of the requirement of most hard disks, and this moment, power supply will be by the PCB printed board to heating module 10 power supplies, make it produce heat, with the heating upper mounted plate, and rely on thermograde to give hard disk, guarantee the operate as normal of hard disk under the low temperature heat radiation.
This portable hard disk anti-vibration and shock heating box is with low cost, and hard disk is had favorable damping, adds thermal effect, and be particularly suitable for vehicle-mounted grade and be easy to vibrate, the environment for use that temperature variation is big, and have portable function, convenient a large amount of copies data.
