计算机固体模拟技术可以通过结构的模拟和随后的工程强度分析评价结果,可以对批量生产的摩擦楔进行重新设计,最终的技术方案是在所用材料参数和结构元件参数的反复修改过程中产生的。建议综合使用CAD和CAE技术,用于改进货车18-100型三元素转向架减振部件中的摩擦斜楔。作为原始样件,选用了参照M1698改进型的设计,并由机务局设计处研制的摩擦斜楔。固体模拟是在自动设计系统SolidWorks的工具介质中完成的。对结构强度的评估是借助ANSYS Workbench13程序包来进行的。在摩擦斜楔数字模型的基础上,取得了轻型化的设计,且能保证其强度要求。将之也与基准设计相比,摩擦斜楔的质量可减轻20%。在此情况下,尽管产生的应力增加了33%,但所获得的斜楔设计仍具有足够的强度安全系数,可满足对其所提出的要求。
Computer simulation of solids can be used to simulate the results of structural simulation and subsequent engineering strength analysis. The friction wedges can be redesigned for mass production. The final technical solution is generated during repeated modifications of the material parameters and structural element parameters used. It is recommended that CAD and CAE be used in combination to improve the friction wedges in the damping element of the Model 18-100 three-element bogie truck. As the original sample, the reference M1698 improved design, and by the Bureau Design Institute developed friction wedge. Solid modeling is done in the tool media for the automated design system SolidWorks. Evaluation of the strength of the structure is done using the ANSYS Workbench13 package. On the basis of the digital model of friction wedge, a light-weight design has been achieved and its strength requirements can be guaranteed. Compared with the benchmark design, the quality of the friction wedge can be reduced by 20%. In this case, the resulting wedge design, despite a 33% increase in stress, still possesses sufficient strength and safety factor to meet its requirements.
