以正规化的刚度矩阵为理论基础，建立了线性柔性平台。通过对柔性平台的刚度矩阵进行正规化处理获得机构的柔度矩阵，进而判断所设计机构的自由度和约束。对所设计柔性平台进行了有限元仿真分析，分析结果表明，所得振型结果与理论计算结果一致，可为多自由度线性柔性机构的设计与分析提供借鉴。
以正規化的剛度矩陣為理論基礎，建立瞭線性柔性平檯。通過對柔性平檯的剛度矩陣進行正規化處理穫得機構的柔度矩陣，進而判斷所設計機構的自由度和約束。對所設計柔性平檯進行瞭有限元倣真分析，分析結果錶明，所得振型結果與理論計算結果一緻，可為多自由度線性柔性機構的設計與分析提供藉鑒。

Based on the theory of normalization of stiffness matrix,a linear flexible platform was established.Through the stiffness matrix of flexible platform normalization process,its flexibility matrix organization was gotten,and then judged the degree of freedom and constraints of the design agencies.Then through analyzing the finite element simulation for the designed flexible platform, the results showed that the results of the finite element analysis was consistent with the calculated theoretical.This could become the reference for the design and analysis of multiple degrees of freedom linear flexible mechanism.
