Improve Productivity and Double Product Development Speed with 3DEXPERIENCE

New data from Dassault Systèmes demonstrates how companies can improve productivity by 30% and accelerate product development by 100%, simply by moving to 3DEXPERIENCE, Dassault’s comprehensive product lifecycle management (PLM) platform.

The Problem

Many organizations are still working with a static, on-premise set of siloed applications. CAD, CAE, MFG, and PLM software each evolved individually, and as such, each has its own data set and its own user interface, 3D modeler, data model, file format, and security configuration. Using data from one application in another means transferring and translating it—which often necessitates a PDM system to manage file versions and traceability, increasing the number of non–value added activities employees must perform just to access data.

In addition, the quantity of data in the organization—no small matter with large file packages—and the potential for mistakes increase exponentially as employees copy files onto local machines. Not only does this result in multiple static versions of data, but it also means a huge likelihood of wasted work, rework, or errors when individuals or teams use the wrong versions of files.

Siloed applications didn’t create siloed disciplines, but their separation doesn’t encourage cooperation. Mechanical, electrical, and systems teams build their own models in their own separate domains, and the first time any team sees the systems fully integrated and the whole product working often isn’t until a physical prototype is tested. It’s no surprise physical prototypes sometimes don’t work even after more than 100 build-test-fix iterations, which means projects are delayed and quality suffers.

The Solution

The 3DEXPERIENCE platform from Dassault Systèmes delivers a unified system with more than 500 applications built natively on a digital platform with just one UI, 3D modeler, data models, and security. Each application accesses data from the shared platform without the need to share, transfer, or translate files between formats. Available on-premise or on-cloud, 3DEXPERIENCE is the single, authoritative source of data—real-time information available to all participants in the system—which eliminates local copies of files, as well as all of the non–value added activities, and increases productivity by as much as 30%.

3DEXPERIENCE also promotes collaboration, since multi-disciplinary teams can work together on a single virtual definition, from a single platform. With the software’s robust test and simulation capabilities, teams can virtually build, test, and fix all issues before ever creating a first physical prototype. This results in a high probability of the first physical prototype actually working as intended, as well as a greatly reduced number of physical build-test-fix iterations. Overall, a coordinated, collaborative platform with shared, synchronized data and leading-edge virtual simulation and testing tools means organizations can dramatically improve their product development speed.

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.”
