Bsr pre-validation system and method with door trim contact point analysis

A BSR pre-validation method with door trim contact point analysis, comprising:

• a step of obtaining door trim design data;
• a step of obtaining a material database, and buzz, squeak, and rattle (BSR) improvement history information;
• a material 1 information extracting step of extracting material information of parts forming a contact surface based on the door trim design data and the material database;
• a material analyzing step of determining a risk of friction noise between matching parts for each contact surface based on the material database;
• a BSR pre-validating step of determining contact surfaces having a squeak risk index or rattle risk index higher than or equal to a preset threshold value based on the material information, the risk of friction noise between matching parts, and a contact point analysis (CPA) matrix for the each contact surface as an expected risk group;
• and
• an improvement measure deriving step of deriving an improvement measure for the expected risk group based on the BSR improvement history information.
