ICEMAKERS’ SPECIAL TEST TRACKS

SPECIAL TEST TRACKS APPLICATIONS

Since the start in 1973, test tracks have been Icemakers’ primary focus. However, not all tracks are necessary linked to snow and ice directly, but to the cold temperature itself! Besides our regular lake- and land track systems, we offer special test tracks in various forms and materials on both lake ice and land.

The main reason for using these special test tracks is to test the changing behavior of vehicles in cold climates. At colder temperatures, materials behave differently than in warmer conditions. For example, rubber seals become more solid and some components might even become more brittle. In colder temperatures, additional acoustic trials in the form of squeaking and rattling may also be more prevalent.

Our special test tracks are not part of Icemakers’ standard offering and are constructed in close cooperation with our customers, to fit their specific needs and requirements. Below are a few examples of the types of special tracks Icemakers can offer.

A SELECTION OF OUR SPECIAL TEST TRACKS

Frequency Sweep Test Track (FSTT)

The aim of the frequency sweep test track is to create an environment where you in a controlled and repetitive way can excite vehicles at different frequencies in order to improve detection and evaluation of acoustic problems, such as squeak and rattle (S&R). Squeak and rattle in vehicles are results of road surface irregularities transferred through the tires and the suspension.

The basic idea behind the FSTT is that a vehicle traveling along the track at a constant speed will be exposed to a constant force, but with a changing frequency.

The frequency increases or decreases as the vehicle moves along the track and the force is created from ribs mounted on the track. Since the distance between the ribs varies, a stepped frequency sweep is achieved.

Cobblestone Track

This type of track has a quite similar test scenario as the frequency sweep test track, with it’s natural stones (cobblestone) creating a randomly variable force instead of a controlled frequency sweep.

Torque Hill Track (Verwindungshügel)

This type of track may be used to test the strength and rigidity of the chassis under an uneven load/torque. This testing scenario is achieved by constructing a special track consisting of multiple smaller snow- and ice hills. When driven over, the chassis gets subjected to different degrees of force working the different parts of the chassis, testing its capabilities.

Chassis Scrape Track

Chassis scrape obstacles are used to test the durability of the vehicles’ underbody against forced scraping in cold temperatures, where materials become more brittle. The obstacles are constructed from ice and can be made in various heights, suitable for different kinds of vehicles. This special track minimizes the ground clearance and subject the underbody to maximum contact with ice and snow.

Pothole Track (Schlaglöcher)

Icemakers can create special tracks with artificial pot holes, in order to simulate driving on a badly maintained road in a cold climate, where materials may react differently due to the lower temperatures. Driving over the potholes subjects the vehicle to sudden and intense shocks and jolts, testing the performance of the chassis, suspension and other systems. 

Stair Track

The stair track uses the same basic concept as the Frequency Sweep Test Track and is also used to test the vehicles for rattle and squeak, by exposing them to different frequencies of force. This track differs from the FSTT in that the different frequencies are achieved by driving along the track at different speeds, rather than getting the full interval whilst maintaining a constant speed.
