Suspension System Performance Validation

Application Summary

In a high performance vehicle, the suspension system does more than hold the car up, it adapts to aerodynamic forces on the vehicle, varying road conditions, and driver inputs. In addition, complex multipoint suspension systems in use in NASCAR® and Formula 1® require the use of modeling and simulation to ensure compliance under load. Significant modeling and analysis is undertaken to account for these variables. However, the final step to maximize performance is live testing to validate the simulation model. To accomplish this, load cells are placed in line with each suspension arm, providing detailed information of the load running through each arm, accurate steering load measurements, and indirect front tire grip enabling adjustments of the suspension system to optimize performance and handling.

Products in Use

LCM Series Miniature In Line Load Cells or LCB Series Fatigue Rated Rod End Tension and Compression Load Cells are each paired with a USB220 USB Output Module

How it Works

LCM Series or LCB Series load cells are threaded in-line with each suspension arm. It is critical to study the load path and avoid any side load and/or moments.
As the vehicle is operated on a test stand or driven, the output signal is sent to the USB220 units.
The USB220 displays and logs the data to a PC via our SENSIT™ software. This data can be used to validate and fine-tune the performance of the suspension system.
