When ultrasonic waves act on the thermoplastic plastic contact surface, it will produce tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is two The acoustic resistance at the welding interface is large, so local high t...

Ultrasonic cutting is a kind of ultrasonic equipment specially used for cutting, and it is one of the important categories of ultrasonic applications. Ultrasonic cutting, through the action of ultrasonic waves, causes the grinding wheel blade to generate instantaneous telescopic vibration in the radial direction, which can cause repeated collisions between abrasive grains and processed objects und...

When the partial pressure in the liquid decreases, the process of the formation, development and collapse of vapor or gas cavities (cavitations) inside the liquid or at the liquid-solid interface is called cavitation. Cavitation is a phenomenon peculiar to liquids, which occurs in the low pressure area inside the liquid, especially at the interface between the liquid and the solid. Cavitation in t...

Power refers to the amount of work done by an object in a unit of time, that is, power is a physical quantity that describes the speed of work. The amount of work is constant, and the shorter the time, the greater the power value. The formula for finding power is: power = work/time. Power is a physical quantity that characterizes the speed of work. The work done per unit time is called power, deno...

Ultrasonic plastic welding is to use the high frequency vibration of ultrasonic to accurately seal two thermoplastic materials in sub-second time. Under the high-frequency sound wave pressure, the entire part connection process is realized in less than 0.2 seconds. The high-frequency vibration of the ultrasonic wave is transmitted to the surface in direct contact with the plastic part. Since the b...

The coronavirus' structure is an all-too-familiar image, with its densely packed surface receptors resembling a thorny crown. These spike-like proteins latch onto healthy cells and trigger the invasion of viral RNA. While the virus' geometry and infection strategy is generally understood, little is known about its physical integrity. A new study by researchers in MIT's Department of Mechanical Eng...
