The editor of the cable displacement sensor explains to you what the prestress is
. Before explaining the prestress, the editor of the cable displacement sensor must understand what prestress is. It is the abbreviation of prestress, before the structure bears external load. , To apply stress to the area under external load in advance to improve the performance of the structure. Let me explain to you the following:
1. The cable displacement encoder can use pre-compression stress to resist the tensile stress or bending moment of the structure, and pre-tension stress can also be used to resist the compressive stress of the structure. Good use of the principle and technology of prestress, it is possible to obtain the effect of improving the structural performance and increasing the structural bearing capacity.
2. Before the engineering structural components bear the external load, prestress is applied to the steel strands in the tension module to improve the bending resistance and stiffness of the components, delay the occurrence of cracks, and increase the durability of the components. For the mechanical structure, the meaning is to generate stress in advance. The advantage is that it can increase the rigidity of the structure itself, reduce vibration and elastic deformation. This can significantly improve the elastic strength of the tension module and make the original resistance stronger.
3. Due to the large tension control error, large measurement error, unpredictable retraction value, low synchronization rate at both ends, inability to achieve dual control of tension and tension, lack of reliable process control methods and Effective detection and evaluation methods and other shortcomings have gradually been replaced by intelligent, numerically controlled tensioning technology.
The prestress of the rope displacement sensor is summarized in the above editor. These are sorted out by the editor in various articles. I hope this article is helpful to everyone.
