The working principle of a kind of self-driving type magneto-rheological vibration damping damper provided by the invention:
1, when bearing less impact load, this moment, the vibrational energy of damper piston and piston rod was less, damper should mainly show as the power consumption effect, the surrender fluid need not to reach yield situation in the damper, it mainly acts on viscous force, during use, it is reciprocating with respect to cylinder barrel that the reciprocal external force at damper two ends promotes piston rod, this moment is because vibratory output is less, power lever vibratory output in the self-induction device is also less, produce induction current in the inductor coil hardly or only produce very little induction current, this moment, the self-induction device participated in work hardly;
2, when bearing the greater impact load, this moment, the vibrational energy of damper piston and piston rod was also bigger, and damper should mainly show as spacing and lock function, and the surrender fluid should be based on the fluid yield force, so need bigger Current Control in the damper under this state; During use, the reciprocal external force at damper two ends promotes piston rod and does bigger double vibrations with respect to cylinder barrel, the interior inductor coil of self-induction device this moment is also done bigger to-and-fro motion in company with power lever, under powerful the action of a magnetic field, produce bigger induction current, and the power of electric current changes and becomes with power vibration of bar situation, the electric current of inductor coil reaches the electromagnetic coil in the cylinder barrel, produce the magnetic field of corresponding size, thereby constantly change the surrender damping force of surrender fluid in the damper, reach the purpose of vibration power consumption on the one hand, also limited the vibration displacement of damper on the other hand.
Compared with prior art, a kind of self-driving type magneto-rheological vibration damping damper provided by the invention has the following advantages:
1, the self-induction device is set in the damper, self-induction current in extraneous vibration processes, and with this as the control energy, externally do not have any energy and rely on, more do not have the stable power requirement, energy-saving and environmental protection, control stability are good;
2, the self-induction device that is provided with in the damper, its faradic power and variation tendency have directly reflected the vibration situation of external environment, need not smart quick sensed system, the assurance that more is easy to get of control effect is better to the adaptability and the robustness of environment;
3, when bearing less vibrating load, damper mainly shows as the power consumption effect, and when bearing the greater impact load, damper not only consumes energy but also spacing, has good adaptive performance;
4, damper structure simplicity of design, processing, convenient disassembly, reusable have good reliability and using value;
5, Applicable scope is wider.
