Problems solved by technology

[0003] At present, the automatic calculation of the B benchmark value of composite materials is generally implemented by writing programs such as Matlab. This method requires user data to be input from the machine where the Matlab computing environment is located, and problems such as data formats have not been well resolved. Need The user manually checks the input data in advance, which is inefficient
In addition, for the Web platform and distributed computing environment, Matlab programs for local computing cannot be effectively connected

Embodiment Construction

[0031] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0032] Such as figure 1 As shown, it is a method for calculating the reference value of composite material B provided by an embodiment of the present invention. The method includes the following steps:

[0033] Step 1: Retrieve and select composite material performance data in the database;

[0034] Step 2: Detect composite material performance data, if there is an abnormal value in the composite material performance data, correct the abnormal value;

[0035] Step 3: If more than two groups of composite material performance data with no outliers come from the same matrix, then the two or more groups of composite material performance data without abnormal values ​​are unstructured data, and the B benchmark is calculated by processi...

Abstract

The invention relates to a calculation method and system for the B reference value of a composite material. The method comprises the steps of: retrieving and selecting performance data of a composite material in a database; detecting the performance data of the composite material, and if there are abnormal values in the performance data of the composite material, correcting the abnormal value; if more than two groups of performance data of the composite material without abnormal values are from the same parent population, determining that the more than two groups of performance data of the composite material without abnormal values are non-structural data, and calculating the B reference value by using a method of processing non-structural data. The system comprises an acquiring module, a detection module, a judging module and a calculation module. According to the invention, links such as data entry and abnormal value processing in a calculation flow of the B reference value of a composite material are improved, so that user operations are facilitated.

Description

Technical field [0001] The present invention relates to the calculation field of the reference value of composite material B, and in particular to a method and system for calculating the reference value of composite material B. Background technique [0002] The allowable index for evaluating the static performance of composite materials generally adopts the B benchmark value. The B benchmark value is defined as: a limit value of mechanical properties. With a 95% confidence level, the value of 90% of the performance value group is not lower than it value. The US military manual MIL-HDBK-17-1F gives the method of calculating the B reference value. After that, the FAA proposed the latest calculation method of the B reference value based on the long-term experience based on the previous method. Based on the above-mentioned foreign research results, my country compiled the aviation industry standard HB 7618-2009 "Criteria for the Expression of Mechanical Properties of Polymer Matrix ...
