What is resonance and why is it so deadly?

Resonance is a condition in which a physical system vibrates at a greater amplitude than other frequencies at a specific frequency. The reason why it is fatal is because there is a process of energy accumulation and release, and each vibration will accumulate positive work, and finally release a huge energy force.

Resonance is when an object produces an amplitude at a specific vibrational frequency that exceeds other vibrational frequencies. Due to the large amplitude generated by the resonance, it is very easy to shatter objects with insufficient toughness, which is why it is so deadly.

Resonance is when two objects have the same frequency of motion. When the frequency is the same, it has a strengthened effect on destruction, so it is lethal to many things.

The vibrational frequency of objects reaching the same is called resonance, and when their frequencies reach the same frequency, the energy emitted is the largest and most deadly.

Resonance refers to the resonance phenomenon when the car is driving. The meaning of low-frequency resonance of automobiles: In fact, it is simply understood as:

It's like taking an airplane, the internal pressure gauge is big, and the ears are buzzing. The principle of low-frequency resonance is that when sound is transmitted through the air to the car body, it is reflected back, resulting in low-frequency resonance.

Low-frequency resonance refers to the phenomenon of low-frequency resonance in the car, that is, when the car is idling in a hot car, the engine resonates at low frequency and makes a lot of noise. It seriously affects the driver, so that the driver has a feeling of headbang in the driver's seat; And driving in traffic jams for a long time will make it very uncomfortable for the ears.

Volvo started out as a sedan manufacturer, and its founders, Swedes Gustaflarson and Assargabrilsson, both worked for SKF, a well-known Swedish manufacturer of ball bearings. Thanks to their foresight and enthusiasm for automobiles, they successfully persuaded the board of directors of SKF to borrow the company's factory in Torslanda in September 1925 to assemble a prototype car, and on August 10, 1926, they were authorized to start mass production of the new car. Volvo's first product was the Volvo V4 convertible, which was launched on April 14, 1927.

During the resonance, the energy of the object to the vibration is continuously accumulated and absorbed, so that the amplitude of the object's vibration is increasing more and more, until the internal structure of the object is destroyed and the natural vibration frequency of the object is changed. Resonance refers to the situation in which a physical system vibrates at a greater amplitude than other frequencies at certain frequencies, and these specific frequencies are called resonance frequencies. <

During the resonance, the energy of the object to the vibration continues to accumulate and absorb, so that the amplitude of the object vibration becomes larger and larger, until the internal structure of the object is destroyed and the natural vibration frequency of the object changes. Scramble resonance refers to the situation in which a physical system vibrates at a greater amplitude than other frequencies at certain frequencies, and these specific frequencies are called resonant frequencies. When the physical system resonates, it can absorb energy from the surrounding environment, and the ability to continuously accumulate makes the object vibrate violently, thereby changing the internal structure of the object.

Resonance, also known as "resonance" in acoustics, refers to the phenomenon of an object making a sound due to resonance, such as two tuning forks of the same frequency coming close, and when one of them vibrates and makes a sound, the other will also make a sound. In electricity, the resonance phenomenon of an oscillating circuit is called "resonance".

The phenomenon of resonance refers to the phenomenon that when an object or system is subjected to external vibration, the vibration frequency of itself is close to the external vibration frequency, and the amplitude will increase significantly. To put it simply, resonance is a phenomenon of energy transfer, when an object matches the frequency of the applied vibrational source with the frequency of the vibrational source, it can absorb more energy and produce a greater amplitude.

The phenomenon of resonance is widely used in many fields, such as mechanics, electronics, and other fields. In the field of machinery, resonance can be used to enhance the vibration amplitude of mechanical systems; In the field of electronics, resonance can be used to select specific frequencies, such as tuning circuits in electronic devices such as televisions and radios.

However, the resonance phenomenon may also lead to the loss of control and damage of the system, such as bridges, caves and halls buildings and other structures will be out of control and damaged under the action of too high frequency, so it is necessary to consider the factors of resonance in the design to avoid the risk of resonance out of control.
