Abstract:

In order to reduce the risk of manual operation and improve the stability of the beaker assembly in blended fabric quantitative analysis system, operating conditions were designed firstly. Then, according to theoretical analysis, dynamic characteristics of fluid sloshing in single beaker were simulated by FLUENT for each operating condition. Results indicate that no water splashed out of the glass beaker, and the beaker bottom is subjected to the pressure action in the form of sine due to fluid sloshing. Finally, static analysis and harmonic response analysis of supporting steel mesh plate were carried out by ANSYS according to the liquid sloshing result.  Results show the fluid sloshing frequency is not fit with the inherent frequency of supporting plate, and the dynamic deformation in the operation process of the beaker assembly and operationc conditions are reasonable and desirable.
