본 발명은 능동 하이브리드 마운트에 관한 것으로서, 보다 상세하게는 기계류에서 발생되는 진동 및 소음을 흡수하여 차단하고 외부 충격으로부터 기계류를 보호하도록 한 능동 하이브리드 마운트에 관한 것이다.TECHNICAL FIELD The present invention relates to an active hybrid mount, and more particularly, to an active hybrid mount that absorbs and blocks vibration and noise generated from machinery and protects the machinery from external shock.

일반적으로, 기계류에서 발생되는 진동 및 소음의 전달을 차단하고 외부 충격으로부터 기계류를 보호하기 위해서는 우수한 성능을 갖는 마운트 시스템의 개발이 요구되어 왔다.In general, in order to block the transmission of vibration and noise generated in machinery and to protect the machinery from external shocks, development of a mount system having excellent performance has been required.

기계류의 진동 및 소음이 지지 구조물을 통해 외부로 전달되는 효과를 감소시키기 위해서는 작은 강성과 감쇠를 갖는 마운트가 효과적인 반면, 기계류의 강체운동 제어와 마운트의 내구성 측면에서는 강성이 큰 마운트가 필요하다.Small stiffness and damping mounts are effective to reduce the effects of machinery vibrations and noises being transmitted through the support structure to the outside, whereas rigid mounts are required in terms of rigid body motion control and durability of the mounts.

마운트 시스템의 공진이 존재하는 저주파수 영역에서는 가진 진폭과 충격력이 크기 때문에, 강성이 큰 마운트를 이용하여 기계류의 과도한 운동을 제한하고 큰 감쇠력으로 충격력을 감소시켜야 하고, 가진 변위와 충격력이 작은 고주파수 영역에서는 작은 감쇠력으로 기계류의 진동 및 소음을 지지 구조물과 절연시켜야 한다.In the low frequency region where the resonance of the mount system is present, the amplitude and impact force are large. Therefore, the rigid mount should be used to limit the excessive movement of machinery and reduce the impact force with large damping force.In the high frequency region where the displacement and impact force are small Small damping forces should isolate machinery vibrations and noise from the supporting structure.

이러한 상반된 요구특성을 만족할 수 있는 마운트 시스템에 대한 연구 개발이 필요하다.There is a need for research and development on a mount system that can satisfy these conflicting requirements.

종래에 널리 사용되고 있는 고무 마운트는 고무재의 탄성복원 및 감쇠 특성에 따라 강성과 감쇠가 결정되며, 가진 주파수와 가진 진폭에 따른 변화는 미미하다. 고무 마운트는 가진 진폭이 작은 고주파수 영역에서는 진동 및 소음 절연에 매우 효과적이나 감쇠가 작으므로 가진 진폭이 큰 저주파수 영역에서의 진동 및 소음 절연성능은 저하된다.The rubber mount widely used in the related art has a stiffness and attenuation depending on the elastic restoring and damping characteristics of the rubber material, and the change according to the excitation frequency and the excitation amplitude is insignificant. The rubber mount is very effective for vibration and noise isolation in high frequency region with small excitation amplitude, but the damping is small, so the vibration and noise insulation performance in low frequency region with large excitation amplitude is degraded.

이러한 고무 마운트의 단점을 보완하여 제안된 유체 마운트는 유체의 강성과 관성트랙의 기하학적인 형상을 조절하여 특정한 저주파수 영역에서의 효과적인 절연효과를 얻을 수 있다. 반면 다른 주파수 영역에서 진동 및 소음 절연성능이 저하되는 단점을 가지고 있다.Complementing the disadvantages of these rubber mounts, the proposed fluid mount can achieve effective insulation effect in a specific low frequency region by controlling the rigidity of the fluid and the geometric shape of the inertial track. On the other hand, vibration and noise insulation performance is degraded in other frequency ranges.

또한, 상기 진동/충격흡수부재(300)에는 상,하의 종방향으로 관통된 복수개의 삽입공(310)이 천공되고, 이 삽입공(310)에는 실린더(400)가 각각 삽입되어 내장되게 설치된다.In addition, the vibration / shock absorbing member 300 is a plurality of insertion holes 310 are penetrated in the longitudinal direction of the upper, lower, and the insertion hole 310 is installed to be inserted into the cylinder 400, respectively. .

상기 실린더(400)는 그 상면이 개구되고 하면은 막힌 원통체로서, 그 상단부의 외주면에는 원주방향을 따라 돌출된 판형상의 돌출부(410)가 형성되고, 상기 돌출부(410)는 진동/충격흡수부재(300)의 삽입공(310)에 실린더(400)의 삽입 시, 진 동/충격흡수부재(300)의 상면에 안착되어 걸림된다.The cylinder 400 is a cylindrical body whose upper surface is opened and the lower surface is blocked. A plate-shaped protrusion 410 protruding in the circumferential direction is formed on the outer circumferential surface of the upper end portion, and the protrusion 410 is a vibration / shock absorbing member.

상기 상,하부의 코일(730)(730')은 서로 반대방향으로 감김되게 구성되되, 상부 코일(730)은 오른쪽 방향으로 감김되고, 하부 코일(730')은 왼쪽 방향으로 감김되어서, 전류를 흘려주면 각각 윗방향과 아랫방향으로 유동전류가 발생된다.The upper and lower coils 730 and 730 'are configured to be wound in opposite directions, and the upper coil 730 is wound to the right direction, and the lower coil 730' is wound to the left direction, thereby providing current. When flowed, flow currents are generated in the upward and downward directions, respectively.

그리고, 상기 코일(730)(730')의 중앙부에는 플런저(720)가 코일(730)(730')에 감싸지도록 설치되어, 코일(730)(730')에서 발생된 유도전류에 의해 플런저(720)가 전자석이 된다.In addition, the plunger 720 is installed at the central portion of the coils 730 and 730 'so as to be wrapped in the coils 730 and 730', and the plunger is formed by the induced current generated by the coils 730 and 730 '. 720 becomes an electromagnet.

따라서, 전자석이 된 플런저(720)에 의해 후술될 축(742)이 윗방향 또는 아랫방향으로 움직이게 된다.Accordingly, the shaft 742 to be described later is moved upward or downward by the plunger 720 which becomes the electromagnet.

한편, 상기와 같이 구성된 압전소자(510)와 전자기 작동기(700)는 별도의 콘트롤러(미도시)를 통해서 제어된다.On the other hand, the piezoelectric element 510 and the electromagnetic actuator 700 configured as described above are controlled through a separate controller (not shown).

이하, 상기와 같이 구성된 본 발명에 따른 능동 하이브리드 마운트의 작용에 대해 설명한다.Hereinafter, the operation of the active hybrid mount according to the present invention configured as described above will be described.

먼저, 본 발명의 능동 하이브리드 마운트(100)는 도 4에 도시된 바와 같이, 기계류의 하면에 지지판(500)의 상면이 접하도록 다수의 마운트(100)가 고정되게 설치된다.First, in the active hybrid mount 100 of the present invention, as shown in Figure 4, a plurality of mounts 100 are fixedly installed so that the upper surface of the support plate 500 is in contact with the lower surface of the machinery.

상기와 같이 설치된 능동 하이브리드 마운트(100)에 기계류에서 발생된 진동 및 소음이 전달되고, 전달된 진동 및 소음은 지지판(500)을 통해 진동/충격흡수부재(300)와, 압전소자(510) 및 전자기 작동기(700)에서 흡수되어 차단된다.Vibration and noise generated from the machine is transmitted to the active hybrid mount 100 installed as described above, and the transmitted vibration and noise are transmitted via the support plate 500 to the vibration / shock absorbing member 300, the piezoelectric element 510, and the like. Absorbed and blocked by the electromagnetic actuator 700.

즉, 수동형 요소인 고무재의 진동/충격흡수부재(300)는 고주파수 영역의 비공진 주파수 대역에서의 진동 및 소음을 흡수하여 차단하며, 전원 및 별도의 외부장치 없이도 전원차단 등과 같은 비상시에도 진동 및 소음에 대한 안정적인 절연성능 즉 차단성을 유지한다.That is, the vibration / shock absorbing member 300 of the rubber material, which is a passive element, absorbs and blocks vibrations and noises in the non-resonant frequency band of the high frequency region, and vibrates and noises even in an emergency such as power interruption without power supply and external device. It maintains stable insulation against ie breakage.

그리고, 압전소자(510)는 기계류로부터 지지구조 즉 지지판(500)으로 전달되는 진동 및 소음을 이에 대한 반력으로서 감쇠시키되, 특히 작동변위는 작지만 큰 힘을 발생시키고 응답속도가 상당히 높은 작동 주파수 특성으로 인해 고주파수 영역의 진동 및 소음에 대한 감쇠효과가 뛰어나다.In addition, the piezoelectric element 510 attenuates vibration and noise transmitted from the machinery to the support structure, that is, the support plate 500, as a reaction force thereto, and in particular, the operating displacement is small but generates a large force, and the response speed is considerably high. Due to this, the damping effect of vibration and noise in the high frequency region is excellent.

또한, 전자기 작동기(700)는, 상,하부의 코일(730)(730') 중 일측이 코일에 전류를 흘려주면 그에 해당하는 유도전류가 발생되고, 이 유도전류에 의해 플런저(720)는 전자석이 된다. 이때 상부 코일(730)에 전류를 흘려주면 윗방향으로 유도전류가 발생되어 플런저(720)가 축(742)을 상승시키고, 하부 코일(730')에 전류를 흘려주면 아랫방향으로 유도전류가 발생되어 플런저(720)가 축(742)을 하강시키게 된다.In addition, in the electromagnetic actuator 700, when one side of the upper and lower coils 730 and 730 'flows a current to the coil, an induction current corresponding thereto is generated, and the plunger 720 makes the electromagnet by the induced current. Becomes At this time, if a current flows to the upper coil 730, an induction current is generated upward, and the plunger 720 raises the shaft 742, and if a current flows to the lower coil 730 ', an induced current is generated downward. Plunger 720 is lowered shaft 742.

한편, 상기와 같이 전자석이 된 플런저(720)는 유도전류의 힘으로 보조지지 판(740)의 축(742)을 윗방향 또는 아랫방향으로 움직이게 하여, 진동원으로부터 지지구조 즉 지지판(500)으로 전달되는 전달력을 감쇠시킨다. 이는 작동변위는 크지만 발생되는 힘 및 응답속도의 한계로 인해 큰 변위의 진동이 입력되는 저주파수 영역의 진동 및 소음에 대한 감쇠효과가 뛰어나다.On the other hand, the plunger 720 which becomes the electromagnet as described above moves the shaft 742 of the auxiliary support plate 740 upward or downward by the force of the induced current, and moves from the vibration source to the support structure, that is, the support plate 500. Attenuate the transmitted force. It has a large operating displacement, but due to the limitation of the generated force and response speed, it has excellent damping effect on the vibration and noise in the low frequency region where large displacement vibration is input.

따라서, 상기와 같은 능동 하이브리드 마운트(100)는 수동형 요소인 진동/충격흡수부재(300)에 의해서 내충격성 확보 및 전원차단 등과 같은 비상시에도 안정적인 성능 유지가 가능하고, 일반적인 작동 환경에서는 수동형 요소에 능동형 요소의 부가로 인해 마운트(100)의 성능이 향상된다. 즉, 능동형 요소인 압전소자(510)와 전자기 작동기(700)에 의해서 고주파수와 저주파수 영역의 진동 및 소음이 효율적으로 감쇠된다.Therefore, the active hybrid mount 100 as described above is capable of maintaining stable performance even in an emergency such as securing impact resistance and shutting off power by the vibration / shock absorbing member 300, which is a passive element, and active type passive element in a general operating environment. The addition of elements improves the performance of the mount 100. That is, vibration and noise in the high frequency and low frequency regions are efficiently attenuated by the piezoelectric element 510 and the electromagnetic actuator 700 which are the active elements.

이상에서 설명한 바와 같이, 본 발명의 능동 하이브리드 마운트에 따르면, 수동형 요소인 고무재의 진동/충격흡수부재와 능동형 요소인 압전소자와 전자기 작동기에 의해 모든 주파수 영역에서의 진동 및 소음을 흡수 및 차단하여 절연시키고, 내충격성을 확보한 효과가 있다.As described above, according to the active hybrid mount of the present invention, the vibration / shock absorbing member of the rubber material, which is a passive element, the piezoelectric element and the electromagnetic actuator, which is an active element, absorbs and blocks vibration and noise in all frequency ranges and insulates the insulation. It is effective to secure impact resistance.
