Abstract

The invention discloses an electromagnetic relay step tolerance optimization method based on varying contribution rates. The method comprises the steps of S1, determining a tolerance optimization standard; according to the relations between key elements and output characteristics and an actual processing capacity, determining a tolerance range of the key elements; S2, determining a number of levels of the key elements; design an orthogonal test, and calculating an output result of each group of orthogonal test; solving the contribution rates of all the key elements; S3, according to a certain tolerance step length, subtracting the contribution rates with the tolerance to obtain a new tolerance range of the key elements; calculating the concentration rates of all the key elements again; S4, in the new tolerance range determined in the step S3, solving an output characteristic fluctuation range of the corresponding new tolerance range; S5, repeating work in the step S3 and S4 till the output characteristic fluctuation range meets the tolerance optimization standard, or the new tolerance range reaches a processing precision lower limit, wherein the new tolerance range is a final result of step tolerance optimization.

Description

technical field [0001] The invention relates to the technical field of relay product design, in particular to a step-by-step tolerance optimization method for electromagnetic relays based on varying contribution rates. Background technique [0002] Electromagnetic relay product design includes overall design, parameter design and tolerance design. The overall design is completed and the system function is realized. The parameter design improves the product's anti-interference performance by changing the central value, and the tolerance design improves the product's anti-interference performance by controlling the design tolerance. The change of the central value will not only affect the anti-interference but also change the product performance, and the analysis is complicated; the tolerance design will not change the central value, and the application range is wider. Therefore, it is of great significance to adopt the tolerance design method to improve the quality consisten...
