Key Features

  • Add-in concept: Seamless integration into the Signature Processing Workbook; Extends processing flow with angle domain capability, etc

  • Data set definition

  • Angle domain conversion

  • Absolute phase reference

  • Offset definition: Multiple methods for alignment of angle data to absolute phase reference

  • Stripchart display

  • Quick spectral or angle map

The LMS Test.Lab Angle Domain Processing Add-In is a member of the LMS Test.Lab Rotating Machinery Testing product family, and provides angle domain processing capabilities to the Signature Throughput Processing Workbook. It processes throughput data towards angle domain results in parallel to spectral maps, in an efficient and user intuitive way. Throughput data can be acquired using the Standard or Advanced Signature Testing workbooks, where missing pulses can be corrected on the fly, and can be marked as an absolute reference within every revolution. Very accurate angle-time relationships can be acquired through the support of high pulse rates.

Key Benefits

  • Convenient and complete angle domain processing functionality starting from fixed sampled time data

  • Accurate and fast angle domain conversion, with build-in antialias protection

  • Angle domain processing parallel to regular Signature processing results

  • Highly accurate tachoprocessing independent of sampling frequencies – support of very high tacho-pulse rates

  • Transparent support of pulseencoders with missing pulses for calculation of torsional vibrations (no need for manual missing pulse correction)

  • Multiple automatic or manual methods for alignment of cycles absolute phase reference

  • Multi-gate and multi-cylinder processing in one processing loop

  • Advanced tracking technology suited to stationary and transient engine applications

  • Interactive and immediate validation of throughput time data and/or continuous angle data using powerful Stripchart displays

  • Transparent integration into the Test.Lab Rotating Machinery Testing product suite

  • Fast and easy reporting

  • Compatible with LMS CADA-X project database

  • Minimum training requirements

  • Windows XP® based, provides familiar operation and compatibility with the wide range of Microsoft Office products.
