摘要:
横梁是自行设计的型砂性能检测装置中最重要的承载部件.横梁体积大，为了优化结构、节约材料，提出在不影响其性能的情况下增加减重孔.利用索达系统公司开发的三维软件对横梁进行三维建模，通过其中的有限元分析模块分析横梁的受力情况，建立合理的约束及载荷模型，并对横梁进行有限元网格划分，最后通过计算机对其进行求解，获得了在工作情况下横梁的应力、应变图.结果表明，在有、无减重孔时横梁危险截面处的最大应力分别为26.211MPa和21.358MPa，横梁的最大挠度分别为0.005531mm和0.003665mm，均远小于许可值，横梁在强度及刚度方面均有较大裕度，为其进行结构优化设计和成本的降低提供了重要依据.
Abstract:
The beam is the most important bearing part in detection device beam of sand properties. To optimize structure and save materials of the beam without affecting its performance, the method of increasing lightening hole was proposed. The model of the beam was established using a threedimensional software (Solidworks) developed by SAUDER system company. The reasonable constrain and load model was set up by the module of finite element analysis which also meshes the beam. Finally, the stress and strain diagram about the beam in working conditions was got through the computer. The results show that the maximum stress of dangerous section in the beam with lightening hole is 26.211MPa and without lightening hole is 21.358MPa; the maximum deflection with lightening hole is 0.005531mm and without lightening hole is 0.003665mm, which are far less than the permit value. So, it demonstrates that the beam of strength and stiffness has significant margin, which provides important basis for the structure optimization design and cost reduction
