New capabilities for vibration and frequency domain available in nCode 11.0

Southfield, MI (April 20, 2015) - HBM nCode, developer of the leading brand of durability, test and analysis software, announces today the version 11.0 release of its software suite. The nCode 11.0 release introduces speed improvements that enable users to rapidly process large amounts of data and state-of-the-art methods for designing and validating components subjected to vibration excitation. “nCode 11.0 focuses on new capabilities for vibration fatigue and frequency analysis, allowing engineers to avoid unnecessary over-design and prevent operational failures” says Paul Roberts, Product Manager at HBM nCode. “Additionally, significant improvements have been made to the overall execution speed of processing test data, for example, an aerospace customer has reduced analysis time of huge data sets with complex flows by 30%.

Vibration Fatigue
The functionality of the vibration fatigue solver in nCode DesignLife has been improved in several areas including new types of loading, new conditions and new calculations. Added methods such as multiple simultaneous PSDs, Sine on Random, and Sine Dwell loading enables improved simulation of real-world conditions and offers benefits for engine and powertrain applications. nCode DesignLife now supports Modal Superposition allowing larger models, more frequency steps, larger frequency range, better fidelity of results and faster analysis.

Virtual Load Generation
Loads are vital for durability prediction, but they can be difficult to measure, load reconstruction can be used from measured strains to calculate input loads by using virtual strain gauges. The Strain Gauge Analysis engine in nCode DesignLife identifies suitable strain gauge locations for the load reconstruction process. The gauge selection procedure also has the capability of generating metrics that assist in selecting the appropriate number of gauges to use.

Multiaxial EN Analysis
nCode DesignLife offers a complete fatigue solution; from high cycle to low cycle, simple to multiaxial, crack initiation to crack growth, all in one package. Significant improvements have been made in version 11.0 to the Jiang plasticity model and the automatic analysis selection methods.

Frequency Analysis

New pre-defined processes allow for auto correlation and cross-correlation of input data with various lags/ scaling options, they can also perform convolution between input data and an impulse/filter kernel response. Other new features include a new waterfall analysis method, zoom analysis, and the ability to generate Campbell plots.
