Damper testing machines

ECONOMICAL, PORTABLE, LINEAR MOTOR BASED SYSTEM FOR CARS, MOTORCYCLES AND TRUCKS

For performance tests and high dynamic characterization of products and materials

General description

STEP Lab, responding to the request of cheaper, easy to use, high performance and green products, presents a new products line, for the characterization and high dynamic testing of shock absorbers. This new line is based on linear motors and its high performance Test Center software platform. The machines are suitable to test damper for cars, motorcycles and trucks. This new family of machines was born to overcome the limitations of hydraulic systems by effectively responding to the demand for high performance, ease of installation and low energy consumption. STEP Lab offers the widest range of electrodynamic systems on the market with peak dynamic loads up to 80 kN and continuous dynamic loads up to 40 kN. STEP Lab is also close to its customers giving the possibility of a wide customization both hardware and software.

  • Research and development laboratories
  • Controls on the production line
  • Quality control laboratories
  • Racing teams
  • Mobile labs for track testing

Features

  • Widest range of loads on the market
  • The machines are controlled through Test Center software with dedicated modules for dampers
  • Exceptional dynamic performance
  • Almost zero maintenance costs
  • Very Low energy consumption thanks to the high efficiency of electrodynamic systems
  • Possibility to manage N machines in synchronized mode so as to create a 4-poster system
  • Possibility of installation on any type of structure and support, alone or up to 8 controlled and synchronized axes
  • Flexible programming of test sequences by Test Center graphic interface
  • Ideal to use in clean room
  • Able to test and manage any type of active shock absorbers (based on stepper motors, DC motors, solenoids)
  • Very wide range of signals and transducers that can be acquired

Advantages

Exceptional dynamic performance and simple installation thanks to the request of only one electric socket and compressed air

Possibility to manage N machines in a synchronized way in order to realize multi-axis systems

Very low electrical consumption due to the high efficiency of the electric motor and absence of mechanical transmission

Zero maintenance due to the absence of a mechanical transmission

Flexible geometric configuration: machine can be purchased as linear actuator without structure

Technical data

STEP Lab is proud to offer the widest range of linear motor based test systems. Our electrodynamic systems are divided into two families: one suitable for flexible use and one dedicated to the field where exceptional dynamics (up to 100G) are required. Both product families are managed by the same controller, scalable to the required performance and have the same software packages available. The HUD / XUD systems, developed for flexible use, have an exceptional price/performance ratio.
