Abstract
Through building mechanical model for bellows combination to ensure the structural factors which impact the natural frequency of bellows combination. Based on response surface thought
use experimental design methods
use the natural frequency of the bellows combination as index and each structural parameter as factor
design quadratic regression orthogonal rotation combination experiment. Each group of test structural parameters combinations analysis model can be founded by using ABAQUS 6. 10 software and extract the natural frequency.Finally
ensure the structure parameter combinations interval which makes the natural frequency maintain at a higher level. Through confirmatory test on the optimized parameters
it shows that the natural frequency of the bellows combination can reach above 1500 Hz after optimizing the interval random structure parameters combinations
