【摘要】：针对复合材料舵水动力载荷的等效施加方法及可行性进行了理论和试验研究。以复合材料双支承舵、悬挂舵为研究对象,以舵叶载荷特性及变形特征为依据,提出了两型舵叶的水动力载荷试验等效施加方法,即双支承舵采用单面多块、悬挂舵采用单面单块加载;并通过有限元仿真分析,分别对两型舵叶在等效载荷与实际载荷作用下的位移、应力分布规律进行对比,验证了载荷等效方法的合理性;进而,制作复合材料悬挂舵模型,并开展了等效载荷下舵叶静强度、刚度特性试验研究,对等效载荷施加方法的可行性进行了验证。
[Abstract]:According to the equivalent composite rudder hydrodynamic load method and the feasibility of the theoretical and Experimental Research on composite materials. Double hanging rudder bearing rudder, as the research object, with the rudder load and deformation characteristics as the basis, put forward two type rudder hydrodynamic load test efficiency method is applied, namely double bearing rudder the single pieces, the single piece hanging rudder loading; and through the finite element simulation analysis, respectively on the displacement type two rudder in equivalent load and the actual load, the stress distribution were compared to verify the rationality of equivalent load method; then, making the rudder model of composite suspension, were carried out. Ye Jing rudder strength equivalent load, stiffness characteristics of the test method of equivalent load is applied, the feasibility is verified.
