Automated evaluation of drive file simulation accuracy

In the area of structural durability testing using servo-hydraulic actuators, developing drive files for the actuators is a major step. Testing outcomes depend on ensuring the simulation accuracy of each drive file. These drive files are developed in an iterative process for different test track surfaces at different road and load combinations till the time we achieve better correlation. Evaluation of simulation accuracy of the drive files is an extensive manual review process, making it time-consuming and resource-intensive. To address this challenge, an application has been developed to automate the comparison of actuator signals with predefined target signal files. This tool enables quick and accurate analysis of each drive file in a test run, facilitating a comprehensive review of signal deviations. Each test run has thousands of drive files based on road-load mix and actuator settings. This application helped us significantly optimize the simulation workflow by reducing the manual effort of reviewing thousands of files and conducting statistical evaluations. The developed solution improves productivity and enhances quality in structural durability assessments using servo-hydraulic actuators.
