Vibration isolation for an engine in an agricultural application required careful selection of mount stiffness and damping properties, as well as proven durability under variable amplitude 3-axis load inputs. AMC differentiates their company through top-notch technical service and they ensured customer confidence with a full durability an alysis taking into account actual part loading history. This an alysis showed the AMC solution is superior to alternatives, and they quickly resolved a fatigue issue that was a huge pain point for their customer.
农业应用中发动机的隔振要求精心选择支撑体的硬度和阻尼特性,并且要考虑在三轴变幅载荷输入下的产品耐用性。AMC 凭借一流的技术服务使公司格外出众,他们在疲劳耐久性分析中全面考虑了实际部件的承载历史,以增强客户的信心。分析结果表明,AMC 解决方案优于其他替代方案,并迅速解决了原本是客户的一大痛点的产品疲劳问题。
AMC engineers use the Endurica EIE, CL and DT solvers to ana lyze the effects on durability of multi-channel load inputs recorded in the field by the customer. A nonlinear displacement-strain mapping is first generated using EIE and finite element an alysis. Next, EIE converts the load history into strain history. Finally, Endurica CL computes fatigue life for the part, in terms of repeats of the given history. Or, if there are multiple load cases to consider, these are scheduled and applied using Endurica DT. Remaining life is tracked until end of life.
Validation against customer field results have shown strong correlation, providing high confidence that AMC’s innovative solutions will work as shown in the simulation.
AMC 工程师使用 Endurica EIE、CL 和 DT 求解器分析客户在现场记录的多通道载荷输入对耐久性的影响。首先使用Endurica EIE 和有限元分析工具,生成非线性位移-应变映射。然后,EIE 将载荷历程转换为应变历程。最后,Endurica CL可以按给定载荷历程的重复次数来计算零件的疲劳寿命。或者,如果需要考虑多步载荷工况,则可以使用 Endurica DT来规划和模拟这些载荷情况,并跟踪(产品在每个载荷工况下的)剩余寿命,直至寿命终点。
对比验证显示,仿真分析结果与客户现场实测结果具有很好的一致性,这为客户使用AMC的产品创新解决方案提供了很强的信心,因为他们能够通过仿真直观了解AMC的产品在实际工作中的表现。
