contacting profile 中文意思是什麼
-
The contacting measurement method with a double probe is put forward after the detailed analysis of the state - of - the - art measuring methods of the thickness of wall. firstly, the theory - profile generatrix is built, and then the movement curve of the track of joint center is constructed, which aims at making the joint center move along the movement curve and keep the fixed sensor touching the wall. the measuring sensor examines the line in its normal direction of the interior wall all the time, the data from the sensor is the thickness value of the wall
論文通過分析國內外變曲率回轉體壁厚測量的現狀，提出了雙測頭接觸式測量方案:通過構造理論輪廓母線，建立鉸鏈中心的運動曲線，使鉸鏈中心始終沿運動曲線運動，以保證固定觸頭與傳感器測頭的連線始終在內壁法線方向上，從而傳感器測頭所得的數值即為壁厚值，該方案經模擬測試實驗取得了預期效果。 -
