Applying True Loads to Simulation Models
Applying accurate loads and boundary conditions to simulation models is critical. Approximations or best guesses lead to inaccurate analysis, flawed conclusions, and defective products.
6D is revolutionizing this process by verifiably determining the true loads that apply to the model and, in fact, any location on the model. In this way, we not only verify that the model accurately simulates reality but also those locations of potential failure or areas of excessive overdesign.
True Load Software
True-Load is a first to market solution to identify where to place strain gauges on unmodified physical parts and then back-calculate loading. Output directly feeds into True-QSE events, a powerful post processing tool that supports rapid virtual iteration. True-Load directly interfaces to FEA fatigue software to make FEA based fatigue with correlated loading events a natural part of the design cycle.
Create multi-channel load cells leveraging your parts and FEA models.
- Determine optimal strain gauge placement from FEA model
- Calculate Load Proportionality Matrices
- Use Measured Strains to back calculate Operating loads
- Create Quasi-Static Events to be used with True-QSE
One of the most challenging tasks for an analyst is to develop load cases for their FEA model that match measured strain values. Typically, it will take weeks to develop the right load cases that match just one or two strain gauges at a single point in time.
True-Load makes that situation a thing of the past. True-Load will determine optimal gauge placement based on the FEA model. Once strains are collected at these optimal gauge locations, the strain data is read into True-Load to calculate load time histories that will typically match the measured strain to within 2% at every point in time. When combined with True-QSE, interrogating any point in the model for strain, stress or displacement is easy and interactive. Typically, it takes a few minutes to determine the strain gauge placement and a few minutes to back calculate the loading profiles.
