And the displacement control of the leaf spring center was transferred to the displacement at load point. then after the load step options configuration, the leaf spring stress circulation under cycle loadings was calculated. the model was validated by the result compare between the rigid extracted from the simulation results and the one out of the rigid test of the leaf spring
使用加載頭和簧片的接觸行為來模擬加載狀況，並將對簧片中心的變形控制轉換為對加載點的位移約束，然後利用載荷步選項配置完成一個載荷循環，由此計算出加載階段下鋼板彈簧內部的應力循環。 -
This dissertation discuss the key technology of wide band digital t / r module, including : architecture of the wide band digital t / r module ; wide band signal generating technology based on ddws ; using fiber technology to transmit data between radar center and t / r moudle. after studying the digtal t / r module technology over the world, this dissertation present a scheme of l band ( 1300mhz ) wide band ( b = 100mhz ) digital t / r module, and design a test board to verify transmitting technology of wide band digital t / r module, it works at l band. it use gigabit fiber components to transmit data between radar center and t / r module, use ddws and quadrature modulate technology to generate wide band radar transmitting signal, all control signal is generated by fpga
本文探討了寬帶數字t / r組件發射通道的關鍵技術，主要包括:數字t / r組件的體系結構、基於ddws技術的寬帶信號的產生以及數字t / r組件收發數據的光傳輸技術。本文在深入研究了國內外數字t / r組件技術的基礎上，提出了一種l波段（ 1300mhz ）寬帶（ b = 100mhz ）數字t / r組件的原理框圖，並且設計了試驗板來驗證寬帶數字t / r組件發射通道技術。該試驗板採用千兆比特光纖技術實現寬帶數字t / r組件與雷達主機的數據傳輸，採用ddws加正交調制技術產生寬帶雷達信號，採用一片fpga完成整個組件的控制。
