DRI’s state-of-the-art kinematics and compliance (K&C) test facility is the only independent site in North America to provide a full suite of K&C tests as well as center of gravity (CG) and moment of inertia (MoI) measurements, including products of inertia, under one roof. Housed in a secure facility, it enables OEMs, Tier 1s, start-ups and motorsport teams to precisely measure and evaluate a vehicle’s suspension system.
At the heart of the facility is AB Dynamics’ SPMM. Not only do we measure using the market-leading machine, being part of the AB Dynamics Group ensures that DRI’s machine is always among the first in the world to benefit from latest technologies and updates.
DRI provides a full suite of standard K&C tests and measurements as a service package. This includes the industry standard tests such as bounce, bounce-pitch, roll, longitudinal compliance, lateral compliance, aligning torque and steering. Our team of highly experienced engineers will manage the test from start to finish.
Our team can also work with you to develop bespoke tests to meet your specific requirements. The SPMM enables the chassis and each wheel to be controlled and manipulated independently providing advanced flexibility.
The SPMM is the only measurement machine to lift, roll and tilt the vehicle enabling the full MoI and CG properties of the vehicle to be derived. Alongside the standard suite of K&C tests, this provides all of the chassis-based data required to create a highly accurate digital vehicle model. Measurement data can be imported into CarSim, CarMaker and MathWorks vehicle simulation software.
Designed around the core principle of faithfully simulating on-road vehicle behavior, the SPMM is the industry’s most technically advanced kinematics and compliance test machine. Accommodating the smallest city cars up to light commercial vehicles, including ‘dualies’ – dual rear-wheeled vehicles, its unique moving body and fixed ground-plane design replicates a vehicle’s interactions with the road surface with unrivalled precision.
Controlled in six degrees of freedom, the SPMM’s moving table applies a combination of roll, pitch, bounce and yaw motion to the vehicle body. The test vehicle is clamped to the table and suspension kinematics are analyzed by moving the table to simulate the motions of the vehicle body that occur on the road. The resulting wheel center movement is measured using AB Dynamics’ Dynamic Arm measurement system.
