A performance test fixture is a precision-engineered device used to securely locate, support, and position automotive components during laboratory testing, durability evaluation, functional verification, and quality inspection.
The fixture reproduces the mounting conditions of the actual vehicle, ensuring repeatable and accurate test results while preventing unwanted movement or deformation during testing.
Custom test fixtures are widely used by vehicle manufacturers, Tier 1 suppliers, research laboratories, and quality inspection departments.
Performance test fixtures support testing throughout the product development and manufacturing process.
Typical applications include:
Engine mounting brackets
Suspension control arms
Suspension bushings
Brake calipers
Brake assemblies
Steering components
Wheel hub assemblies
Axle systems
Powertrain components
Chassis assemblies
They are commonly used for:
Product R&D
Durability testing
Fatigue testing
Functional validation
Quality control
Production inspection
Maintenance verification
How Does a Test Fixture Work?
A custom fixture accurately positions the component under test while applying boundary conditions that closely replicate real vehicle installation.
