| Abstract: | The strength reliability of hydraulic machine rack is affected by the uncertainty of geometric parameters, load parameters, material parameters and so on. Parametric modeling of large hydraulic machine rack is made based on the effect using APDL language. Monte-Carlo method and response surface methodology method are used for fitting the samples of response surface by finite simulation cycles. The samples are regression analyzed, and the functional relationship of response variables and basic variables is obtained. As the result, probability strength design and sensitivity analysis of hydraulic press rack are achieved. |
