| For large plastic check well, the strength analysis and structure optimization design are the key technical
problems, ANSYS software was adopted to establish the plastic check well's finite element analysis model. Also,
orthogonal test method was used to study the effect of wall thickness of check well, diameter of main pipeline, the height
of main pipeline, diameter of particles, location level of particles on stress-strain. Experimental results showed that the
influence of size parameters on the stress were as follows: diameter of particles had bigger influence than location level of
particles on stress-strain which had bigger effect than wall thickness of check well, and wall thickness had bigger effect
than diameter of main pipeline and which had bigger influence than the height of main pipeline. Furthermore, the
influences of size parameters on the strain were: the height of main pipeline was bigger than diameter of particles,
diameter of particles was bigger than diameter of main pipeline, and diameter of main pipeline was bigger than location
level of particles which was bigger than wall thickness of check well. The size of structure optimization was also
obtained: wall was 8 millimeters, diameter of main pipeline 800 millimeters, the height of main pipeline 800
millimeters, diameter of particles 800 millimeters and location level of particles 100 millimeters. |
