Abstract
本发明提供了一种循环弯扭组合载荷通用加载装置，包括：边界支撑模块，构造成刚性框架结构，用于提供反力支撑；被加载对象模块，用于连接试验船体；弯矩加载模块，用于向所述被加载对象模块施加弯曲力矩；扭矩加载模块，用于向所述被加载对象模块施加扭转力矩；检测模块，用于检测加载载荷及试验船体的应变数据；所述弯矩加载模块与扭矩加载模块相互独立设置，可独立控制并包括液压作动器，通过调节所述液压作动器输出的位置和 / 或数量以改变所施加弯矩与扭矩的载荷比。本发明可实现弯扭载荷比例无级调节与任意组合加载，既可完成单一弯曲或扭转试验，也可精准模拟复杂海况下的弯扭组合载荷，适配不同尺寸与结构形式的船体模型试验。
