5200t折弯机上横梁的虚拟设计
|
摘要
虚拟设计是以计算机仿真和建模技术为支撑，利用虚拟产品模型，在产品的实际加工之前对产品的性能进行仿真和评价，以达到产品的最优目标。
5200t折弯机的上横梁是重型折弯机中结构和受力最复杂的大型构件，因结构性缺陷导致构件失效的事例大都发生在上横梁上。本课题是应用虚拟设计技术研究5200t折弯机的上横梁，通过创建反映上横梁特性的仿真模型，在设计与加工出来之前，对其性能进行全方位分析与预测，从而在虚拟的环境中完成上横梁的可行性研究和优化。根据上横梁的分析数据，进一步研究上横梁的结构性缺陷和应力集中，对整体结构和局部结构进行创新和优化，在设计阶段就可消除了各种结构性缺陷，降低了应力集中。
通过对5000t折弯机全面测试和试运行，上横梁的各项性能指标均能满足设计要求，与虚拟设计的数据基本相符，证明5200t折弯机上横梁的虚拟设计是成功和有效的。
The dummy design is based on the technology of computer emulation and modeling and by using the virtual product models to emulate and evaluate the performance of products before they are actually manufactured so as to obtain the optimum performance of the products.
The upper beam of 5200t Press Brake is a large size component with the most complex structure and receiving the most complex forces on the heavy- duty press brake. Cases of component failures due to structural defects mostly happen on the upper beam. The question for study here is to research the upper beam of 5200t Press Brake by applying the technology of dummy design, create the emulated model reflecting the characteristics of the beam and conduct an all-around analysis and forecast of its performance before the actual design and manufacture take place so as to accomplish the feasibility research and optimization of the upper beam in the dummy circumstances. By using the analytical data and through a further research on structural defects and stress concentration of the upper beam, a creation and optimization on the whole and partial structures can eliminate various structural defects and reduce the stress concentration at the stage of design.
After the overall tests and commissioning of 5200t Press Brake, every performance parameter reaches the design requirement and basically coincides with the data in the dummy design, which proves the dummy design of the upper beam of 5200t Press Brake is successful and effective.
