System for analysis of the condition of the running gear of rail vehicles
First Claim
1. A system for analyzing conditions of a running gear of rail vehicles, the system comprising:
- a number of force measurement devices for detecting forces and/or torques acting on a rail measurement zone, wherein the force measurement devices are arranged on the rail measurement zone,a plurality of sonic measurement devices for detecting sound waves that occur when the rail vehicle travels over the rail measurement zone, andan analysis unit configured to correlate electrical measurement signals supplied simultaneously by the force measurement devices and sonic measurement devices with one another and superimpose the electrical measurement signals to thereby draw inferences about the conditions of the running gear of the rail vehicle.

Abstract
The object to create a system and a method which allows better running gear diagnosis of rail vehicles is achieved by the present invention by arranging a number of force measurement devices on the rail measurement zone to detect the forces and/or torques acting on the rail measurement zone, such that the system also comprises a number of sonic measurement devices for detecting the sound waves which occur when the rail vehicle travels over the rail measurement zone. The present invention thus offers a diagnostic system for analysis of the condition of wheel bearings and wheel geometries in particular in which the forces and sound waves occurring when the rail vehicle travels over the rail can be detected and analyzed, so that more reliable inferences about the condition of the running gear of the rail vehicle can be drawn from them.

12. A method for analyzing conditions of a running gear of rail vehicles in a rail measurement zone comprising the following steps:
-
having a rail vehicle travel over the rail measurement zone; detecting forces and/or torques that act on the rail measurement zone when the rail vehicle travels over the rail measurement zone, by a number of force measurement devices; detecting sound waves occurring when the rail vehicle travels over the rail measurement zone, by a number of sonic measurement devices, wherein the sonic measurement devices are directional microphones having a certain directional characteristics that are mechanically uncoupled from the rail measurement zone; and analyzing electrical measurement signals supplied by the force measurement devices and the sonic measurement devices to draw inferences about the condition of the running gear of the rail vehicle therefrom, wherein the forces and/or torques in the rail measurement zone are detected and detection of the sound waves is performed concurrently, wherein the analyzing includes; correlating and superimposing the electrical measurement signals supplied by the force measurement devices and the sonic measurement devices; and analyzing the correlation between the electrical measurement signals supplied by the force measurement devices and the sonic measurement devices to thereby draw inferences about the condition of the running gear of the rail vehicle. - View Dependent Claims (13, 14)
