Description

Ceramic tile elastic modulus on-line measuring device Technical Field The utility model relates to the field of ceramic tile testing, in particular to an online testing device for the elastic modulus of a ceramic tile. Background The modulus of elasticity is an important property of an object and is determined by the material properties of the object itself. In the production, manufacture and application processes of ceramic tiles, the elastic modulus of the ceramic tiles is one of important indexes, and the detection of the elastic modulus is also of great significance to the performance monitoring of products and the satisfaction of various application scene requirements. The traditional method for detecting the elastic modulus of the ceramic tile is mainly divided into two major categories, namely a static method and a dynamic method. The static method can calculate the elastic modulus according to Hooke's law by measuring the stress and strain of the material in a stress state through a three-point bending method, a compression method and the like, and has the advantages that the testing principle is simple, the operation is relatively easy, the shape and the size of a test sample are generally required to be cut and processed into a certain shape, the data calculation such as the sectional area is convenient, the influence on the result by factors such as the loading rate, the loading time and the like in the testing process is large, the discreteness of the testing result is relatively large, and the measurement is required to be carried out for multiple times to obtain the average value so as to improve the accuracy. Static methods are more applied as sample testing and do not have the operability to test each product on-line, continuously. The dynamic rule applies dynamic excitation to the ceramic material to generate vibration, the natural frequency, vibration mode and other parameters of the material in the vibration process are measured, and the elastic modulus is calculated according to the vibration theory of the material. The resonance method is to make a ceramic sample generate resonance by an excitation device, measure the resonance frequency of the sample and calculate the elastic modulus according to parameters such as the size, the shape, the quality and the like of the sample. The dynamic method has the advantages of high test speed, small damage to the sample, small influence of environmental factors on the test result, high accuracy and being particularly suitable for measuring the elastic modulus of the ceramic material at high temperature. The detection of the resonance frequency of the sample is generally detected by spectrum analysis after vibration sound collection or by using a paste-type vibration sensor, the method of sound collection is not suitable for the environment with high noise of the ceramic tile production line, and the method of detecting the vibration frequency by using the paste-type vibration sensor is not suitable for continuously and online continuous detection of the production line product.
