IQC Steering Column Test System

Tailored to your requirements, our automotive Steering Column Test System detects faults based on user-defined metrics – with statistically generated tolerance.

Based on more than 30 years of experience, the Signalysis Steering Column Test System delivers 100% inspection confidence to your manufacturing floor. This production test system replaces subjective tests with advanced vibration, sound, motor current and travel velocity algorithms and metrics.

IQC MATERIAL HANDLING

Controls the part in place and provides the required vibration isolation from the manufacturing facility.

IQC AUTOMATION

Controls steering column operation through a defined list of functional tests.

IQC MEASUREMENT SYSTEM

Acquires dynamic response data from a defined set of transducers, sampling rates, digital filters, and sample sizes.

IQC ANALYSIS ENGINE

IQC Analysis Engine employs high-level post-processing in time and frequency domains to detect faults in mechanical or moving parts.
