Analytical simulation is a powerful tool that can allow for understanding the dynamic behavior and fatigue life of any structure. However, one of the most challenging tasks involved with developing a simulation is developing accurate and realistic load cases, which replicate field strains in the structure, so that it may be used for validation. Once a representative finite element model (FEM) of a structure is created, challenges arise when understanding and applying dynamic loads to the FEM so that correlation and validation with physical testing is accurate. One step further in complexity is being able to calculate dynamic stress profiles for the entire structure, and use those results for further investigation, in this case fatigue estimates.

Historically, analysts have had to rely on expensive prototyping and time-consuming full vehicle measurements, even within the iterations of one design concept. Analyze-Build-Test is quickly becoming a thing of the past, as product development companies strive for quick to market designs. Simulation experts at Adaptive Corporation, in conjunction with Terex, were able to circumvent this traditionally laborious process and develop an efficient and accurate validation process. Our team has leveraged the use of ANSA, ABAQUS, Wolf Star Technologies True-Load™ software and Fe-Safe, to develop an FEM, understand the dynamic mechanical loads and develop a duty cycle for the Terex telescoping boom chassis. This body of work can and will be subsequently used for design, simulation, fatigue analysis, validation and engineering development of iterations of the same chassis structure, as well as similar chassis designs.

The general steps of the process are as follows: FEM Creation of Assembly FEM of the chassis structure was created using ANSA pre-processor software. Instrumentation and Data Acquisition To successfully calculate mechanical loads acting on the Terex Telescoping Boom Chassis for the FEM, accurate strain measurements were required. Using the FEM and the Wolf Star Technologies True-Load™ software, optimal strain gages placement was identified and installed on a test chassis. Strain gage time history data for various proving ground events, such as cornering, washboard, curbs and potholes. Load Calculation and Development Using the time history data for the optimal map of strain gages, the FEM and True-Load™ software, equivalent (dynamic) unit loads were calculated. Fatigue Analysis Using dynamic stress results from the FEM, given a duty cycle that included a combination of various proving ground events, fatigue life estimates of the Terex Telescoping Boom Chassis and critical welds were calculated. Calculating the mechanical loads for this project allows Terex the ability to rapidly iterate on designs for this chassis, as well as provide a starting point for other similar chassis designs. This ultimately saves time and money in their product development cycle by reducing the efforts of traditional design-build-test cycle, by means of “virtual validation.”

SIMULIA Online Training: Fatigue Methods for fe-safe

Dates: November 11 and 13

(There is no course on Wednesday 11/14)

Time: 12:00 PM to 4:30 PM EST

(includes a 30-minute break)


Fatigue Methods for fe-safe is a live online course presented by SIMULIA.

The course covers the metal fatigue methods implemented in fe-safe including infinite life, stress life, and strain life fatigue.

[Register]

Why is metal fatigue important?

Because fatigue failures are expensive. A component failing before its intended useful life can mean expensive product launch delays, product recalls, warranty claims, and legal liability.

According to NIST and Battelle institute studies in 2004, fatigue failures cost companies $190 billion annually, when corrected for inflation.

The lectures and demonstrations will include:

  • Fatigue from FEA models
  • Infinite life methods
  • Stress-life methods
  • Strain-based fatigue
  • Plasticity and Fatigue
  • Variable Amplitude Loading
  • Multiaxial Fatigue
  • Critical Plane methods

No installation?

No problem! All examples will be demonstrated by Dassault Systemès Instructors!

Title: Simulation Driven Design using the 3DEXPERIENCE Platform

Thursday, October 11 at 1:30 PM

Presenter, Maria Sullivan, Senior Application Engineer, Adaptive Corporation

Abstract:

Collaborate, Innovate, Design, Simulate and Build faster.

In today’s product development world, teams are challenged to drive development costs down, shorten design cycles exponentially and deliver superior products to their customers. Simulation is a key driver in this process. To help demonstrate how product development teams can achieve success, our fictional sports equipment company was founded. To compete in an ever-changing market, this company must rapidly and accurately deliver an innovative golf driver and putter. Leveraging the 3DEXPERIENCE platform, this company’s simulation team seamlessly interacted and collaborated with the entire project team to influence design decisions. The team drafted design concepts, set up a project schedule and assigned tasks, developed and validated these concepts with simulation, and visualized these designs with real-time rendering and Virtual Reality applications. There was no loss of information in translation. The team functioned as a collaborative entity, rather than a hands-off approach between individuals. With this strategy, the simulation team focused more on their expertise, and less on revision tracking, delivery and weighty presentation of results for the rest of the team. The end result was a much faster go-to-market time with a better and more competitive product.
