Measurement system suits race car analysis

A BERU F1 Systems product story
Edited by the Engineeringtalk editorial team Oct 23, 2007

BERU F1 Systems' chassis dyno measurement system has been designed to suit forces encountered in F1, NASCAR and other high-load applications.

Chassis and vehicle dynamic engineers who struggle to achieve sufficient accuracy for measuring suspension setting and wheel displacement can benefit from BERU F1 Systems' new chassis dyno measurement system.

Race teams and engineers using current off the shelf scales found they were only really effective for static analysis and therefore have a limited weight range of up to 1000kg.

In addition, existing systems rely on a single loadcell per corner, reducing accuracy and preventing engineers from analysing lateral loads.

As restrictions on testing in motor sports grow, coupled with research into new areas of untapped development, the use of chassis dynos is growing.

Obtaining high-quality data from this analysis is vital to offset the investment.

BERU F1 Systems' solution is to create a highly rigid pad with four loadcells per wheel.

With an expectation that an active chassis dyno could see loads up to 3000kg, the product has been designed to suit forces encountered in F1, NASCAR and other high-load applications.

"The four high-accuracy loadcells design provides linear and consistent results", says BERU F1 Systems' Strain Gauge System Manager Simon Roberts.

"And with the ability to provide excellent immunity from contact patch changes both for vehicle positioning, tyre size differences and camber changes during suspension movements, we are expecting that the benefits for users will be significant".

To improve analysis, outputs options are available for logging systems, either differential mV/V or single-ended amplified 0-5V.

BERU F1 Systems can provide a single averaged output for the scale pad and/or individual output of the four loadcells in each scale pad if required.

The bespoke nature of this testing allows BERU F1 Systems to design scale pads with specific dimensional or fixing requirements.
