Data Acquisition Technologies

Data Acquisition Technologies Capturing performance data directly in the lab or from the field for analysis is at the heart of all WESTEST testing services. WESTEST Data Acquisition Equipment captures a wide range of precise and repeatable data at high sample rates. Equally important is ensuring that captured data can be effectively analyzed and interpreted with powerful data assessment programs and integrated with other WESTEST systems and software.

Featuring the Somat eDaq Data Acquisition System

WESTEST uses the Somat eDaq Data Acquisition System. This system features selectable rates up to 250,000 samples per second and collects data on force, strain, acceleration, pressure, temperature, speed, flow, torque and displacement. The data can be easily imported to analysis programs and used as critical inputs to drive the the product development process.

Applications for Testing Data

  • Aiding in the Design Process: In-service data provides known inputs and responses useful to the designer during the product development cycle.
  • Accelerated Durability and Simulation Testing: Tests cost money and take time, so extracting as much information as possible from every test using advanced editing and analysis techniques is critical.
    Simulation software optimizes testing to maximize laboratory productivity and helps transform data into useful, functional information through advanced analysis and damage editing. That means less time in development and faster time to market. Typically, the initial step in the process is to collect meaningful information about the “real-world” operating environment through field-recorded data. During test modeling and simulation, information obtained through dynamic monitoring of the equipment under test provides valuable, sometimes critical, information about the character of its performance. Laboratory testing lets engineers duplicate the environment components are subjected to and observe failures that occur.
  • Force and Load Life-Cycle Testing: A component can be subjected to an entire life cycle in the lab in a short period of time. Drive files can be created for lab tests using block loading or Remote Parameter Control (RPC) simulation techniques.
  • Component Life Estimating: WESTEST computer software combines actual strain information with known physical properties of the components material to estimate the component’s useable life. This information helps the designers to assess the effects of material composition, surface finish and other factors on service life.
  • Component Stress Analysis: Measuring actual stress characteristics (through strain measurement) gives designers valuable information to use in determining material, shape and size decisions.
  • Computer Simulation: Stress and strain values can be determined and incorporated into finite element analysis (FEA) models.

Benefits

  • Critical design information helps minimize machine production costs as well as warranty costs
  • Information is available at various levels of detail – clients get the detail needed at minimum cost
  • Computerized analysis allows laboratory-testing set-ups to accurately simulate field conditions
  • Designs based on measured stress values are more accurate than designs using assumed stress values
  • Minimizing field testing by effectively deploying field data and replicating field performance in the lab reduces development costs
