Mechanical property test and analysis on the main body frame structure of electrical dust precipitator

Resumo

The objective of this work is to test the strength reserve, the working stability, the vibration performance and the dynamic response under stochastic load on the optimized main body frame structure of a type of electrical dust precipitator. The test program is established which is a test process, as well as a feedback process. The strength prototype test is carried out to study the strength reserve of the structure. Based on the mechanical model, the modal analysis, the buckling analysis, and the seismic analysis is carried out using ANSYS to study the working stability and the vibration performance of the structure. The test results show that the strength reserve of the structure is sufficient, the main body structure will not be instability in working, the structure’s landscape orientation rigidity is feasible, the two-dimensional rigidity is even, and its torsional rigidity is better. The Maximum lateral displacement and stress meet the standard requirements. Obviously, the main body structure is optimized perfectly and the method is feasible that to do the performance tests after structure optimization design.
