Definitions
- test benches or test benches are used on which the motor vehicle to be tested is driven on rollers or unrolled independently.
- a dynamometer known per se is schematized for this, in which at least the wheels of the vehicle 1 driven by the drive axle are in rolling contact with rollers 2 of the chassis dynamometer.
- To drive and targeted braking (output) of the rollers 2 is a powerful electric motor 3, whose operation is controlled by a control and monitoring unit. 4 is controlled.
- test stands encounter those with regard to the frequency range Vibrations that are coupled into the motor vehicle, at about 50 Hz to its technical limits.
- the invention has for its object to provide a device for performing a vibroacoustic examination on a motor vehicle, which has at least a front and rear axle, with a test bench, against which the motor vehicle is tied and the middle or directly with at least one of the two axes is connected via at least one power flow, along which at least one vibration generator of a first type for generating vibrations of less than 50 Hz is provided, such that the motor vehicle is to be converted into realistic as possible nach0-e vibration states in which the motor vehicle are sensory examined and evaluated can.
- care must be taken to ensure that the assembly and technical equipment required to be handled is the vibration behavior of the motor vehicle at different speeds To measure road surfaces and different tire profiles to keep as low as possible.
- a device according to the solution is specified in claim 1.
- a solution according to the method for performing vibroacoustic examinations on a motor vehicle is described in claim 12.
- the concept of the invention advantageously further features are the subject of the dependent claims and the description below.
- test bench concept is based on the previous practice, in which the motor vehicle to be examined is a tire rolling contact with provided on the test casters or treadmills. Rather, according to the solution proposed, the completely opposite a test bench bound motor vehicle along a at least one drive shaft, usually at its two opposite ends
- Fixing provisions for the wheels provides to connect to a vibration generator of a second kind, which is able to couple vibrations of over 30 Hz, preferably of over 100 Hz in the motor vehicle.
- the motor vehicle is thus to be put into a high-frequency vibration state which it assumes, as it were, when the motor vehicle travels along a road surface in a real situation.
- the advantage of the device according to the invention is to be seen in particular in the fact that the vibration generation within the motor vehicle is not caused by a physical contact between tire tread and road surface, but the high-frequency vibrations are realized within the motor vehicle by the targeted coupling with suitably selected vibration generators, the are able to generate vibrations, preferably in a frequency range between 30 and 500 Hz.
- the vibration coupling into the motor vehicle at any point of the vehicle body, but is suitable for a realistic as possible, simulated adjustment of a real driving situation, the coupling of high-frequency oscillations along at least one drive axle of the motor vehicle in an area where the Tires are attached to the drive shaft.
- both the initiation of uniform accelerations and low-frequency alternating loads are required for the simulation of driving maneuvers and different driving loads in a manner that already exists in a realized test stand according to the embodiment shown in Figure 3 is the case, as well as the targeted introduction of high-frequency vibrations for the adjustment of rolling noise and also caused by the interaction between the road and tires within the vehicle vibrations.
- so-called servohydraulic cylinder which are able to initiate both a coupling uniform deflections and low-frequency vibrations in the motor vehicle and this not only along the vehicle vertical but also in addition Direction of the vehicle longitudinal and transverse axis.
- three separate servohydraulic cylinders are provided for each coupling point on the motor vehicle.
- electrodynamic shakers which are likewise preferably provided in three implementations per coupling point, are suitable for coupling high-frequency vibrations along the vehicle vertical, the vehicle longitudinal direction and vehicle transverse direction into the vehicle.
- electrodynamic shakers which are likewise preferably provided in three implementations per coupling point, are suitable for coupling high-frequency vibrations along the vehicle vertical, the vehicle longitudinal direction and vehicle transverse direction into the vehicle.
- two different concepts for coupling the high-frequency vibrations into the motor vehicle have proved to be particularly advantageous.
- the sensory detected vibrations are compared with the reference vibration pattern and generated when occurring deviations correction signals that are used to control the corresponding vibration generators.
- a control loop is formed, with which it is possible, the motor vehicle under specification of certain reference vibration pattern in a real simulated vibration state offset.
- motor vehicles tied up on a test bench in vibration states that correspond to the most varied driving situations, for example driving on differently selected road surfaces, driving with different tires and associated different tire profiles, driving in wet or dry Road conditions, etc. All real driving situations and conditions allowed to simulate the test bench designed in accordance with the solution without having to carry out the assembly-technical effort to provide for appropriate road surface and tire conditions.
- the motor vehicle to be examined is connected without any tires to the test stand and the associated vibration generators, by means of which the motor vehicle can be displaced into real-world-modeled vibration states.
- Fig. 1 shows a schematic cross section through a test bed with tied
- the fastening devices 9 are each connected directly or indirectly with servo-hydraulic loading units 10, by means of which the fastening devices 9 and, connected thereto, the entire motor vehicle 1 can be uniformly displaced spatially or oscillated at frequencies of up to 50 Hz ,
- 9 three servohydraulic load units (10 x , 10y, 10 z ) are provided per fastening device whose Kraftfluß therapies are each oriented orthogonal to each other.
- the servohydraulic loading units (10 x , 10 y , 10 z ) are fastened on the one hand to a mechanically fixed abutment 11 on the one hand and connected to the fastening device 9 on the other hand.
- the motor output unit 3 is in each case articulated via a movable rotary shaft 12 to the fastening device 9, which ensures that the drive unit 3 rests in each case and experiences no vibrations through the load units 9.
- the Kraftflußcardien are each oriented spatially orthogonal to each other.
- the deflection control of the high-frequency vibration generators (13 x , 13 y , 13 z ) is carried out by means of a control unit, not shown, which are able to initiate high-frequency vibrations according to a predetermined vibration pattern in the motor vehicle 1.
- the basic principle for vibration excitation of the motor vehicle is largely identical to the two presented concepts according to FIG. 1 and FIG.
- the operating loads for the simulation of driving maneuvers on the servohydraulic load units 10 in the frequency range between 0 and 50 Hz are initiated.
- the high-frequency vibration generators 13 which are excited according to a predetermined vibration pattern.
- a reference sensor 14 is provided on the motor vehicle 1, which detects the actual vibration state of the motor vehicle 1.
- This actual oscillation state is compared with a reference oscillation pattern which, as already mentioned in the introduction to the description, has been obtained during a test drive.
- the vibration generators 10 and 13 are correspondingly corrected in order to obtain a vibration compensation to the predetermined reference vibration pattern.
