Embodiment Construction

[0029] like figure 1 As shown, it is the original side plate model with vertical stiffeners.

[0030] The method for optimizing the distribution of side plate ribs of the present invention comprises the following steps:

[0031] (a) The modal analysis of the original model of the side plate is carried out by HyperMesh software, and the first-order fixed frequency f10 and the second-order fixed frequency f20 of the original model of the side plate are obtained;

[0032] (b) Divide the design area and non-design area of ​​the original model of the side plate, the design area is the main plane area of ​​the panel, and the non-design area is the bending edge of the side plate and the screw installation area; and set the parameters of the reinforcement and the reinforcement method, specifically The structural parameters are: rib height 5mm, rib width 5mm~30mm, stamping angle 45°~60°, rib pattern distribution is concave rib symmetrical distribution; under the constraint of a single...

Abstract

The invention provides a side board ribbing distribution optimization method, a side board and a washing machine provided with the side board, and relates to the field of washing machines. The optimization method is used for obtaining optimal ribbing layout, the frequency fixing characteristic of the side board is improved, the stiffness of the side board is high, and the washing machine is small in vibration amplitude and low in noise during work. According to the side board ribbing distribution optimization method, modal analysis is conducted on a side board original model, then morphologic optimization of reinforcing rib layout is conducted on the side board, a side board optimized model with optimal ribbing distribution is obtained, and then whether design requirements are met or not is verified. By means of the method, the obtained side board is applied to the washing machine, the problems of insufficient static stiffness and dynamic stiffness of a washing machine side board and resonance are solved, and accordingly the side board deformation problem of the washing machine in product transport and product falling processes are well improved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a side plate bead distribution optimization method, a side plate and a washing machine with the side plate. Background technique [0002] When the washing machine is working, especially when it is dehydrating, the cylinder rotates at a high speed, which may easily cause excessive vibration displacement of the side plate, which exceeds the national standard. When the fixed frequency of the side plate is close to the vibration excitation frequency point of the washing machine suspension system at the highest dehydration speed, that is, it is basically in the resonance point area, which will cause greater vibration. It is generally required that the fixed frequency of the side plate of the washing machine is about +-5Hz on the vibration excitation frequency point of the washing machine suspension system, that is, the fixed frequency of the side plate is at least 5Hz lower than the vi...
