In the field of engineering blasting, according to the requirements of blasting safety regulations, the general use is "cm s", of course, the relatively small vibration signal can be forever mm s, 1cm s = 10mm s, vibration measurement is an important link, and the blasting vibrometer is specially used to measure the blasting vibration speed of the equipment. So, what exactly does the unit of vibration velocity measured by the blast vibrometer "mm s" mean?
First, we need to understand the basic concept of vibration. Vibration refers to the constant and repetitive motion of an object within a certain range and can be broken down into various forms of vibration, the most common of which is simple harmonic vibration. In simple harmonic vibration, amplitude is a measure of the magnitude of the vibration, and the unit is a unit of length. For the measurement of vibration velocity, we usually use "mm s" as the unit, which represents the amount of displacement of the vibration per second.
Specifically, the "mm" in "mm s" represents the amount of displacement, that is, the displacement value of the object from the equilibrium position at a certain moment; Whereas, "s" represents the time unit second, and "s" represents the amount of displacement per second. Therefore, "mm s" indicates the amount of displacement that the object moves per second, which is the speed of vibration.
The vibration velocity measured by the blast vibrometer is measured in "mm s", which means that the equipment can measure the vibration velocity generated by the blast. In blasting works, the shock wave generated by the ** will produce huge vibrations to the surrounding environment, and this vibration may cause damage to buildings, roads, bridges, etc. Therefore, by measuring the vibration velocity with a blast vibrometer, it is possible to understand the extent to which the vibration produced by the blast affects the surrounding environment, so that appropriate measures can be taken to protect the safety of buildings and infrastructure.
In practice, the burst vibrometer usually sets a threshold alarm, and the instrument will automatically alarm when the measured vibration velocity exceeds a preset threshold. This alerts the relevant personnel to take countermeasures in time and reduces losses caused by excessive vibration.
In summary, "mm s", as a unit of vibration velocity measured by a blasting vibrometer, is an important parameter to measure the vibration generated by blasting. By understanding and mastering this parameter, we can better assess the impact of the blasting project on the surrounding environment and take effective protective measures to ensure that the project is carried out safely and smoothly.
