什么是预测性维护？工程仿真中的示例以及它是如何工作的？
Predictive maintenance (PdM) is a proactive strategy that uses measured data and simulation models to anticipate equipment failures before they occur. Instead of waiting for a breakdown or performing maintenance on a fixed schedule, PdM monitors the condition of assets in real time and uses analytics to determine when intervention is needed. In this article, [...] 什么是微动疲劳失效？ | 预测与挑战
Fretting fatigue failure is one of the more insidious failure modes in mechanical systems where small oscillatory motions occur between contacting surfaces under load. It lies at the intersection of contact mechanics, fatigue theory, nonlinear modeling, and crack growth. There is an experimental setup for a fretting test in a fatigue testing machine, as shown […]
如何使用 Python 进行 CAE 自动化：专家教程和行业应用
What is CAE Automation and Why Use Python? CAE automation is the process of streamlining simulation workflows—geometry creation, meshing, solver setup, and post-processing—using scripts instead of manual clicks. Python plays a central role because of its flexibility, open-source ecosystem, and deep integration with tools like Abaqus, Ansys, and LS-DYNA. By reducing repetitive tasks and enabling […]
什么是冲击动力学？低速冲击、高速冲击及Abaqus仿真
Impact happens when two objects hit each other with a sudden force in a short amount of time. Impact dynamics covers how structures respond to sudden loads. Low velocity impact (≈1–10 m/s) typically causes indentation and delamination; high velocity impact (>100 m/s) produces inertial, wave and penetration effects. By understanding both low and high velocity […]
什么是成形仿真？| 完整指南 + Abaqus 仿真
Metal forming simulation is the computational process of replicating metal shaping operations using finite element analysis (FEA) tools. Metal forming is one of the most widely used manufacturing processes to shape metals into functional parts. From automotive body panels to aerospace structural components, forming processes involve large plastic deformation of metals and require precise control […]
结构性火灾分析究竟是什么？您的建筑物做好了防火准备吗？
Structural Fire Analysis assesses the thermal and mechanical behavior of structural components under intense heat. It achieves this by combining principles from heat transfer, structural mechanics, and material science. As urban development and infrastructure expand, ensuring the resilience of structures under extreme conditions—particularly fire—has become a critical concern for engineers and designers. Structural Fire Analysis […]
复合压力容器：生产和模拟方法的最佳指南
What is a composite pressure vessel? A composite pressure vessel is a high-performance container manufactured from fiber-reinforced polymers designed to safely store liquids or gases under extreme pressures. Compared to a conventional metallic pressure vessel, it delivers a significantly higher strength-to-weight ratio, superior corrosion resistance, and improved fatigue life. Understanding the structural integrity of these […]
Abaqus 连接器元素 | 类型、用例和设置
In Abaqus Finite Element Analysis (FEA), modeling joints, fasteners, and mechanical connections can be complex and time-consuming—especially with traditional contact and mesh-based methods. Abaqus Connector elements offer a simpler, more flexible alternative. Abaqus connector elements let you define mechanical relationships—like springs, hinges, or dampers—between parts without detailed contact definitions. They’re ideal for capturing relative motion, […]
工程中的数字孪生是什么？它如何改变仿真？
A digital twin is a dynamic virtual representation of a physical object or system that uses real-time data and simulation capabilities to mirror its real-world counterpart. Digital twins work by creating a continuous feedback loop between physical assets and their digital models through sensors, IoT connectivity, and advanced analytics, enabling monitoring, simulation, and optimization of performance [...] 复合材料仿真入门 + Abaqus 复合材料示例
Did you know that more than 50% of failures in composite structures come from incorrect design or simulation? Composites are everywhere—in aerospace, automotive, energy, and beyond. Their unique strength-to-weight ratio makes them powerful materials, but modeling and simulating them is never straightforward. To run a successful composite simulation in software like Abaqus, you need more […]
