Embodiment Construction

[0027] Such as figure 1 Shown is the flowchart of the method of the present invention. First, carry out three-dimensional modeling of the original moving beam, simulate the static and dynamic mechanical properties of the beam according to the actual working conditions, and analyze the simulation data to obtain the objective function of the optimal design of the beam, that is, to determine the factors that affect the performance of the beam: beam rib structure, rib Thickness, upper guide rail support rib structure, and determine the evaluation indicators for evaluating the performance of beams: beam quality, maximum coupling deformation, maximum coupling stress, and first-order natural frequency.

Abstract

The invention discloses a multi-target optimization design method for a machine tool cross beam on the basis of orthogonal test analysis. According to the method, designing is conducted from the three aspects including the cross beam rib plate structure, the rib plate thickness and the inclined angle formed when a guide rail arranged on the cross beam supports a rib plate. The method comprises the following steps that three-dimensional modeling is conducted on an original cross beam, and the static and dynamic characteristics of the original cross beam are analyzed to determine cross beam optimization factors and evaluation indexes; the cross beam rib plate structure, the rib plate thickness and the inclined angle formed when the guide rail arranged on the cross beam supports the rib plate are selected as test factors, the levels of all the factors are determined, a simulation test is conducted on a combination of all the factors by selecting an orthogonal test table, and analytical processing is conducted on simulation data through a comprehensive balance analysis method to obtain an optimal parameter combination; the rationality of the optimization design parameter combination is determined by comparing all the properties of the cross beam before optimization with all the properties of the cross beam after optimization. According to the optimization design method, the optimization test parameter combination is obtained through small test time number, and the method is reasonable, feasible and easy to operate and has the typicality and symmetrical comparability.
