Abstract:
A method and system for evaluating and tuning axle systems includes at least one test rig on which one or more physical axle systems are mounted. A full vehicle model and a road description are used with the test rig to test and evaluate or tune the axle system as would be conducted on a real test track. The full vehicle model is modified to remove the characteristics of the axle system under test. The remainder of the full vehicle model produces output signals in the form of displacements or loads that are transmitted as inputs to the test rig to apply those signals. The test rig measures output signals in the form of complementary displacements or loads that will become inputs to the vehicle model in place of the removed model of the axle system under test. In this manner, the physical axle system under test is inserted into a real time model of the full vehicle, road and driver.
Abstract:
A dynamic vehicle tester providing integrated testing and simulation for determining characteristics of a unit under test. Changes occurred on the unit under test are dynamically obtained, considered and incorporated in generating test conditions to be applied to the unit under test. Additionally, durability testing is conducted using such techniques that compares a physical specimen under test to a real-time model of that specimen.

Abstract:
A method and system for evaluating and tuning tires includes a test rig on which one or more physical tires are mounted. A full vehicle model and a road description are used with the test rig to test and evaluate the tire as would be conducted on a real test track. The full vehicle model is modified to remove the characteristics of the tire or tires under test. The remainder of the full vehicle model produces output signals in the form of displacements or loads that are transmitted as inputs to the test rig to apply those signals. The test rig measures output signals in the form of complementary displacements or loads that will become inputs to the vehicle model in place of the removed model of the tire under test. In this manner, the physical tire under test is inserted into a real time model of the full vehicle, road and driver.
Abstract:
A vehicle tester using integrated simulation model and physical parts under test for determining effects of the physical parts to a complete vehicle incorporating the parts. A simulation model representing the vehicle excluding the physical parts is provided. A test scenario is applied to the simulation model. The response of the simulation model is translated to a test condition applying to the physical parts under test, to obtain the physical parts response to the test condition in real time. Responses and changes occurred on the parts under test are dynamically obtained and incorporated into a calculation of the effects of the physical parts to the vehicle using the simulation model. A report of the calculated effects is then generated.
