The invention discloses a force measuring structure for a navigation body, the navigation body and a load measuring method of the navigation body. The force measuring structure comprises a plurality of segmented force measuring shells which are arranged in the axial direction of the navigation body and connected end to end. A connecting structure of two adjacent segmented force measuring shells comprises an annular boss located at one end of one segmented force measuring shell and a connecting sleeve located at one end of the other segmented force measuring shell, and the outer circumferential face of the annular boss is connected with the inner wall face of the connecting sleeve in a sealed mode. A mounting plate is arranged in the segmented force measuring shell, the mounting plate is perpendicular to the axial direction of the navigation body, a force measuring sensor is mounted on the mounting plate, and the force measuring sensor is fixedly connected with the end face of the annular boss; the force measuring sensor is used for measuring the internal force of the navigation body when the navigation body deforms at the connecting structure after being subjected to external force. The internal force of the internal structure is measured under the condition of free navigation of the navigation body, the internal force of a plurality of key positions in the free movement process of the navigation body is directly obtained, the load history in the movement process is recorded, and the real load condition of the underwater navigation body is determined.

    一种用于航行体的测力结构、航行体及其载荷测量方法,包括沿航行体轴向设置的多个首尾连接的分段测力外壳;相邻两个分段测力外壳的连接结构包括位于一分段测力外壳一端的环形凸台以及位于另一分段测力外壳一端的连接套管,环形凸台的外周面与连接套管的内壁面密封连接;分段测力外壳内部设置有安装板,安装板与航行体轴向垂直,安装板上安装有测力传感器,测力传感器与环形凸台的端面固定连接;测力传感器用于测量航行体受到外力后在连接结构处发生形变时的内力。实现在航行体自由航行的条件下进行内部结构内力的测量,直接获得航行体自由运动过程中多个关键位置的内力,记录运动过程的载荷历程,明确水下航行体的真实载荷情况。
