Iran-Made Vibration Meter Measures Displacements with High Precision
“The advantages of this vibration meter are measuring small displacements (up to micron accuracy), measuring angular changes (thousandths of degrees), measuring stress and strain, the possibility of measuring point displacements (vertical and horizontal), vibrations, oscillating and damping modes of the structure, possibility of discrete and continuous (advanced) studying, simplicity of the method and no need to use multiple devices and computers (compared to similar methods), etc.,” said Ali Salehpour, the managing director of the company.
He added that measurement of bridge vibrations, vibrations of sensitive devices like press, atmospheric turbulence, size of displacement changes and vibrometry of large structures (dam, tower, etc.), stress, strain and deformation of structures from a distance, etc. are other applications of this vibration meter.
Vibration meter is an ideal measuring device for fast and precise checking of vibrating parts, machines and systems.
In a relevant development in August, Iranian researchers had also managed to obtain a formula that determines the condition of structures for reuse after an earthquake.
"In the project, titled ‘determining the intensity index in the assessment of the risk of seismic collapse of structures by considering the aftershocks’, we managed to provide an assessment process by which the probability of the collapse of structures by aftershocks can be determined as a numerical value,” said Fatemeh Soleiman Meygouni, a PhD student at Amirkabir University of Technology.
“Considering that in quake-prone countries, including Iran, there is a need to check the condition of structures after an earthquake to determine whether they are habitable or not, in this project we achieved a formula that can be used to examine the condition of structures after an earthquake,” she added.
“By using the results of the project, we can minimize the loss of life and prevent the wastage of financial resources,” Soleiman Meygouni said, adding that among the features of this plan, mention can be made of applicability in investigating the situation of real buildings because the methods proposed by previous researchers did not provide such a possibility.
