Testing Center, Streparava’s strength

The challenge to be competitive requires the use of modern product development techniques. All the components are tested at the design stage in order to reduce project lead time and ensure performance of the final product.
Streparava has made the strategic choice of setting up a Testing Center to perform product validation tests autonomously and become an even more reliable partner and fulfil all customer requirements.

 

 

Types of test and measurements:

 

Multiaxial dynamic road simulation test

 

Monoaxial, biaxial or three-axial test on a single part or subsystem

 

Component self-qualification tests

 

Approval tests for complete systems

 

On-vehicle field data acquisition

 

Damage evaluation with data processing

 

Test time history processing

 

Application of strain gauges, accelerometers, potentiometers and various types of transducers

 

Data statistical analysis and post-processing

The challenge to be competitive involves the use of all modern techniques of product development.

The tests on components carried out in the design phase allow to reduce the lead time of the project and allow to give the customer a product already approved for the characteristics of functionality.

Streparava has chosen to adopt a modern Testing Center that allows us to be self-employed in the qualification tests of our products and to propose to the customer as a full partner and reliable supplier.
