Through harmonic vibration test and harmonic simulation analysis, the first natural frequency of controller bracket did not meet the experimental test requirements that proposed by the manufacturer (greater than 2000Hz). Through modal analysis of controller bracket, we could optimize controller bracket from design structure, processing technology, handling and other aspects. Cast aluminum material ZALSi12 was adopted. After modal analysis, the frequency of optimized structure was 2374Hz, which meets the experimental requirements proposed by the manufacturer.
