Road simulation test stand

摘要

The disclosed embodiments include a test stand (100) for the simulation of forces and moments introduced into a motor vehicle or into parts of a motor vehicle during driving operation. In order to allow a simulation of road journeys which is as realistic as possible, it being possible at the same time to dispense with vehicle-specific excitation or activation signals, there is provision, according to the invention, whereby the test stand (100) has at least one wheel contact plate (2) for receiving a vehicle wheel (1) and at least one first actuator (3a, 3b) connected at one side to the foundation (101) of the test stand (100) and at the other side to the wheel contact plate (2), for moving the wheel contact plate (2) along a first axis (L1), preferably along the vertical axis, relative to the foundation (101) of the test stand (100).

主权项

1. A test stand (100) for the simulation of forces and moments introduced into a motor vehicle or into parts of a motor vehicle during driving operation, the test stand (100) having the following:
at least one wheel contact plate (2) for receiving a vehicle wheel (1); and at least one first actuator (3a, 3b), connected at one side to a foundation (101) of the test stand (100) and at the other side to the wheel contact plate (2), for moving the wheel contact plate (2) along a first axis (L1), along the vertical axis, relative to the foundation (101) of the test stand (100), the at least one first actuator (3a, 3b) being connected to the wheel contact plate (2) in such a way that the wheel contact plate (2) is rotatable about a first horizontally running tilting axis (K1); the test stand (100) also having at least one second actuator (4, 5), engaging on the wheel contact plate (2), for rotating the wheel contact plate (2) about the first horizontally running tilting axis (K1); the at least one first actuator (3a, 3b) being connected to the wheel contact plate (2) via a joint arrangement (9) which allows a rotational movement of the wheel contact plate (2) relative to the foundation (101) of the test stand (100); and the joint arrangement (9) having a third rotary joint (15) which allows a rotational movement of the wheel contact plate (2) about an axis of rotation (D) relative to the foundation (101) of the test stand (100), the axis of rotation (D) running obliquely with respect to the first tilting axis (K1) and obliquely with respect to the second tilting axis (K2).
