Test stand for testing chassis of motor car, has module for determining corrections based on mathematical-physical models describing characteristics of actuators and mathematical-physical model describing characteristics of chassis

摘要

The stand (100) has end effectors (105a, 105b) for providing introductory forces and moments in a structure (103) and wheel carriers (102). A module (109) actuates actuators of manipulators (104, 106) such that errors arising between target and actual values of a position of the effectors and/or the forces and moments are corrected. The module determines the corrections based on mathematical-physical models describing kinematic, resilient and dynamic transmission characteristics of the actuators and a mathematical-physical model describing transmission characteristics of a chassis (101).
