摘要: 以采用壳体非线性无矩理论所确定的碟形弹簧薄膜位移与薄膜应力作为初始状态,采用壳体线性有矩理论对碟形弹簧进行了弯曲位移与弯曲应力分析.分析表明:与薄膜应力相比,弯曲应力是不能略去的;而与薄膜位移相比,弯曲位移是可以略去的.因此,对碟形弹簧而言,以壳体非线性无矩理论确定位移是合理的,而以壳体线性有矩理论确定附加弯曲应力也是可行的,同时也是必要的.Abstract: The linear moment theory of shells is applied to the analysis of bending displacements and stresses in disks with the membrane displacements and stresses obtained from the non linear membrane theory of shells as the initial states.According to the results of analysis,it can be confirmed that,the bending stresses in the disks play important role in disk selection but the bending displacements are negligible in comparison with the membrane ones.Hence in disk analysis,it is reasonable to determine the displacement field by nonlinear membrane theory and it is also both feasible and necessary to solve the bending stress firlds with linear moment theory.
