Drop Test Automation through Remote Sensing System
During vehicles development, many different tests will be conducted to acquire performance data for production release. One specific test used to develop the rollover safety deployment strategies is the static drop test. The static drop test requires controlling the tipped roll angle of a vehicle using an electronic protractor, open loop electronic lift, and a rope to trigger the release (or static drop) of the angled test vehicle. This is a highly labor‐intensive process which oftentimes is only achieved after multiple attempts.
This unique invention reduces the repetitive time required under current procedures, enhances the personnel safety, generates a repetitive process and streamlines data archival.
The objective of this work is to develop a method that provides a tool to systematically compute critical roll angles based on vehicle parameter inputs, generate prescribed test angles based on required test angle increments, initiate lifting or lowering mechanism to set the test vehicle sample at requested test angles, provide a sensory system to offer a safe environment around the test vehicle, and initiates an efficient and consistent test initiation release process.
Concept and functionality:
This system is designed to systematically compute critical roll angles based on vehicle parameter inputs, and then generates the prescribed test angles considering the required angle increments, as example, figure 1, shows the vehicle in in drop position with certain test angle. It initiates the lifting or lowering mechanism to set the test vehicle at the requested angles and maps the test sequence to archived and referenced data. A sensory system is also utilized to provide a safe environment around the test vehicle by delivering warning indications. The controlled environment of the test also provides repeatabili...
