案例分享丨Endurica携手Technetics：以耐久性创新重塑充气密封技术

Capable of adapting to varying environmental and service conditions, inflatable seals can be expanded and contracted pneumatically or hydraulically to accommodate changes in components that move in relation to one another, and those that are frequently connected and disconnected.

充气密封件能够适应多变的环境和服务条件，通过气动或液压方式膨胀和收缩，以适应相互移动的组件以及频繁连接和断开的部件。

Endurica CL™ is used to predict the initiation of a crack with propagation criteria and to study different seal extrusion profiles.

Endurica CL™用于预测裂纹萌生（基于扩展准则）并研究不同密封挤出型材。

Non-linear material models (Ogden Hyperelasticity) were considered for FEA an alysis through ABAQUS combined with ENDURICA for fatigue life prediction.

通过ABAQUS结合ENDURICA进行有限元分析时，采用了非线性材料模型（Ogden超弹性模型）以预测疲劳寿命。

Prediction of residual life for the seal is estimated with the help Endurica DT™ software solutions.

密封件的剩余寿命预测通过Endurica DT™软件解决方案实现。

The seals operate at up to 250 kPa inflation pressure, with a mean temperature of 10°C.

密封件的工作压力高达250 kPa，平均温度为10°C。

The seals must function for a specified number of years while enduring lyophilizer cycles without cracking.

密封件需在指定年限内正常工作，承受冻干机循环而不开裂。

An alysis with Endurica CL™ and DT™ helped Technetics to design better inflatable seals by considering the large strain behavior, leveraging the parameterized modeling techniques, and fatigue an alysis.

通过Endurica CL™和DT™的分析，Technetics优化了充气密封件设计，综合考虑大应变行为、参数化建模技术和疲劳分析。

Prediction of fatigue life has helped engineers at Technetics to accelerate the design life cycle for the best in class products to maintain the market leading position. 

疲劳寿命预测帮助Technetics工程师加速设计周期，打造顶尖产品以保持市场领先地位。

Additionally, fatigue an alysis with Endurica has allowed Technetics to respond quickly and effectively to customer needs and to ensure delivery of “right the first time” solutions.

此外，通过Endurica的疲劳分析，Technetics能够快速高效响应客户需求，确保提供“一次成功”的解决方案。

“In optimizing a geometry to extend the fatigue life of a product I ran a few iterations of inner-cavity geometries and found one specific geometry with Endurica that achieved 500,000 cycles to failure in contrast to the 30,000 I had before.

“在优化几何形状以延长产品疲劳寿命时，我通过Endurica对内部空腔几何形状进行了多次迭代，最终找到一种特定几何形状，其失效周期从原来的30,000次提升至500,000次。

 It’s more than a 10-time improvement and that’s really significant.These concrete numbers are really powerful in helping us and our customers to make good decisions.”

这一超过10倍的改进意义重大。这些具体数据极具说服力，能有效帮助我们的客户做出明智决策。”
