Body-mounted Component Durability Testing

Assess and validate the durability and expected life of body-mounted vehicle components to minimize warranty cost.

 

Assessing and validating the durability of body-mounted vehicle components—interior elements like instrument panels, dashboards, seats, and electrical systems, as well as exterior items such as mirrors, roof racks, hitches, and storage containers—is critical to minimize warranty costs and ensure passenger safety. OEM engineers, Tier 1 suppliers, and test laboratories perform these evaluations to replicate operational stresses, identify failure modes, and confirm that components maintain structural integrity and functionality throughout the vehicle’s life cycle.

Test Methods
Durability testing of body-mounted components involves applying controlled multi-axis loads, vibration, and motion to simulate real-world vehicle operation. Interior components like dashboards, seats, and electrical modules, and exterior components such as mirrors, roof racks, and hitches, are subjected to dynamic and static loading, thermal cycling, and environmental conditions to replicate service stress. Multi-axis systems provide repeatable, precise motion profiles, capturing deflection, strain, and fatigue behavior over extended cycles. Data acquisition tracks structural response, while software enables automated sequencing, real-time monitoring, and correlation to vehicle-level performance. These methods support design validation, life prediction, and optimization of mounting points, materials, and assembly methods to ensure reliable operation under repeated use.

Test Results
Durability test results provide insight into fatigue life, stiffness, and failure points of interior and exterior body-mounted components. Manufacturers and labs use this data to optimize designs, validate assembly methods, ensure passenger safety, and minimize warranty claims while confirming that components maintain functionality over vehicle life.

MTS Product Solutions
MTS Multi-Axial Simulation Table (MAST) Systems replicate operational loads and vibrations experienced by interior and exterior body-mounted components. Integrated with FlexTest® controllers, RPC® Connect software, modular test components, and hydraulic power units, MTS solutions provide precise, repeatable motion, automated data acquisition, and analysis. Engineers can evaluate durability, fatigue, and structural response accurately, supporting design validation, accelerated life testing, and improved reliability of mirrors, roof racks, seats, dashboards, and other body-mounted components.

  • Multi-Axial Simulation Table (MAST) Systems reproduce multi-axis loads, vibration, and motion on body-mounted components such as dashboards, seats, mirrors, and roof racks. They provide repeatable, high-fidelity simulation of vehicle-induced stresses to evaluate durability and predict service life.
  • FlexTest Controllers provide high-bandwidth, deterministic control for multi-axis component testing. They enable accurate, repeatable application of mechanical, vibrational, and thermal loads, supporting precise measurement of fatigue, stiffness, and structural response of interior and exterior components.
  • Modular Components for Automotive Test Applicationallow flexible configuration of test rigs for body-mounted component durability. They support mounting, instrumentation, and adaptation for a range of interior and exterior components, facilitating realistic load paths and accurate stress replication.
  • RPC Connect Software streamlines test execution, monitoring, and data analysis. It integrates motion profiles, captures multi-axis responses, and enables correlation to vehicle-level performance for interior and exterior component durability assessments.
  • Series 295 Hydraulic Service Manifolds provide stable, low-noise hydraulic distribution for multi-axis testing of body-mounted components. They deliver precise pressure control to actuators, ensuring accurate, repeatable application of loads during durability testing.
  • SilentFlo™ 515 & 525 Hydraulic Power Units supply quiet, stable hydraulic power for multi-axis testing. Their low acoustic signature and precise pressure control enable accurate simulation of mechanical loads on dashboards, seats, mirrors, and other body-mounted components.
