Definitions
- the present invention relates to a rail vehicle and a method m connection with a rail vehicle.
- Rail vehicles are usually made up having a carriage body which is supported by two bogies with one or more axles and associated wheels. When driving such a rail vehicle along a track, vibrations and oscillations from the track are propagated through one or more bogies to the carriage body. If the vibrations conform with the natural frequency of the carriage body, an oscillation is induced m the carriage body.
- carriage bodies with a high natural frequency have been built by making them rigid and of a limited length so that the frequency of the vibrations has essentially been lower than the natural frequency of the carriage body.
- Swedish Patent 509,118 discloses a railway vehicle and a method for such a vehicle for reducing lateral oscillations m the carriage body of the railway vehicle by dynamically separating a partial mass from the total mass or bulk of the carriage body.
- the partial mass is dynamically separated from the bulk of the carriage body with the aid of springs and damping means.
- the bulk of the carriage body must have a natural frequency which is higher than the frequencies that are excited by the sinusoidal motion of the bogies and irregularities m the track.
- a further ob ect of the present invention is to provide a rail vehicle whose lateral oscillation, owing to the sinusoidal motion of its bogie, is minimised.
- One more object of the present invention is to provide a method for minimising lateral oscillations m a rail vehicle.
- An additional object of the present invention is to provide a method for minimising the effect of the bogies on the oscillations of the carriage body.
- the field of application of the invention is pre- ferably rail vehicles intended for high speeds, but the invention can be used for all types of rail vehicles.
- a rail vehicle according to the invention comprises a carriage body supported by at least two bogies, the carriage body comprising a body part, which at least m the lateral direction is displaceable m relation to the remainder of the carriage body.
- a rail vehicle according to the invention is characterised m that it also comprises a measuring means adapted to measure lateral motion of one of the bogies, a control means, which receives a signal, informing about the lateral motion of the bogie, from the measuring means, and a drive means for moving the body part m the lateral direction, the control means being adapted to control the drive means to move the body part m response to the signal from the measuring means, thereby counteracting lateral oscillations m the carriage body.
- a laterally displaceable body part m response to a measured lateral motion of a bogie By actively controlling, according to the invention, a laterally displaceable body part m response to a measured lateral motion of a bogie, it is possible to obtain essentially complete elimination of the excitation of carriage body vibrations while at the same time the mass of the body part need only be a small part of the total mass of the carriage body. It is also possible to reduce the weight of the vehicle since the rigidity requirements are lower m a vehicle according to the invention compar- ed with previously known vehicles owing to the fact that the natural frequency of the carriage body is allowed to be lower.
- the inventors have realised that the lateral oscillations m a carriage body are excited mainly by the sinusoidal motion of the bogies of the rail vehicle.
- the carriage body cannot be considered a rigid body and it is therefore difficult to filter out the relevant frequencies from measured oscillations of the carriage body. Consequently it will be extremely dif- ficult to damp the oscillation of the carriage body m the lateral direction by merely measuring the oscillation of the carriage body. By instead measuring, according to the invention, the motion of the bogies, it will be considerably easier to compensate for the oscillation applied by the bogies.
- the body part is advantageously displaced perpendicular to a longitudinal axis of the carriage body.
- the control means is advantageously provided with information about the dynamic properties of the rail vehicle, which has been obtained through experiments or theoretical calculations and which is used by the control means to control the body part motion performed by the drive means m such manner that oscillations m the carriage body are counteracted.
- the control means must have detailed information about the dynamic properties of the rail vehicle.
- the lateral motion of at least one of the bogies and the lateral oscillation of the carriage body are measured with the aid of a first measuring means and a second measuring means, respectively.
- the control means uses the signals from both the first and the second measuring means to control the drive means to move the body part for the purpose of counteracting lateral oscillations of the carriage body.
- the lateral oscillation of the carriage body is advantageously measured by means of an accelerometer which measures acceleration m the lateral direction.
- the longitudinal acceleration of the attachment of the transverse damping means to the car- riage body is measured.
- the bending of the carriage body can be determined by carrying out the measurement m at least two points which advantageously are located as far away as possible from the longitudinal symmetry axis of the carriage body.
- the body part constitutes at least 1% of the mass of the rail vehicle m order to optimally counteract lateral oscillations of the carriage body.
- advantages of the invention are achieved also in the case where the body part constitutes less than 1% of the mass of the rail vehicle.
- the measurement of the lateral motion of the bogie can be carried out in a large number of ways. It is preferred to measure the transverse motion of the bogie by means of a gyro .
- the measurement of the lateral motion of the bogie can alternatively be carried out, for example, by measur- ing the force of the transverse damping means arranged between the bogie and the carriage body.
- the transverse damping means serve to damp the turning of the bogie in the lateral plane in relation to the carriage body.
- the measurement can be carried out by measuring by means of an accelerator the lateral acceleration of a point which is outside the centre of turning of the bogie.
- Fig. 1 is a schematic view of a rail vehicle accord- ing to a preferred embodiment of the present invention.
- Fig. 2 is a schematic block diagram of the function of a rail vehicle according to the present invention.
- Fig. 1 is a schematic view of a rail vehicle com- prising a carriage body 1, a body part 2, which is suspended by means of springs 3 from the body 1.
- the body part 2 is displaceable in the lateral direction essentially perpendicular to the longitudinal axis of the carriage body with the aid of a drive means 4.
- the body part consists of e.g. a transformer.
- the carriage body is supported by bogies 5, 6 which are suspended from the carriage body and turnable about a centre of turning 7, 8 each.
- Each of the bogies has two axles 9, 10, 11, 12 and associated wheels 13.
- a control means 14 is also arranged on the rail vehicle and is connected to the drive means 4 via a control line 15.
- An accelerometer 16 is arranged m the centre of the rail vehicle for measuring lateral oscillations of the carriage body perpendicular to the longitudinal axis of the carriage body.
- the accelerometer is connected to the control unit 14 via a line 17.
- On one bogie 5 a gyro 18 is arranged, which is connected to the control unit 14 via a line 19.
- a transverse damping means 20 is arranged between a fixing point 21 on the carriage body and a fixing point 22 on the bogie.
- Fig. 2 is a schematic block diagram of the function of a rail vehicle according to the present invention.
- the control means 14 corresponds to the contents within the dashed frame 23.
- the bogie 5 When the rail vehicle is driven on rails, the bogie 5 will move along a sine curve. The transverse motion will be detected by the gyro 18 and will be pass- ed on to the guide means 14 via the line 19.
- the sinusoidal motion is represented as a disturbance 14 affecting the bogie 5.
- the lateral oscillation of the rail vehicle is affected by the transverse motions 24 of the bogie m a process 26.
- the transverse motion of the bogie m the form of sinusoidal motion is measured by the gyro 18 and passed on to the control means m block 27.
- block 27 there is information about the dynamic properties of the rail vehicle, i.e. information about the process 26, which consists of the connection between the lateral motion of the bogie and the lateral oscillations of the carriage body.
- block 27 a reproduction of the process is made and passed on to block 28, where the signal from block 27 is added to the signal from block 31.
- the sum from block 28 affects the drive means which is represented by block 29, m response to the signal from block 27 and block 31.
- the force of the drive means is added to the force of the sinusoidal motion of the bogie, which is represented by block 25.
- Block 27 represents feedforward control .
- Block 30 is con- nected to a regulator 31 m the control means.
- the drive means 29 is actuated m response also to the signal from block 31.
- Blocks 30 and 31 represent feedback control m the system.
- the signal from block 27 is considered most m order to obtain a quick reaction to the interference 24.
- the accelerometer 16 can be replaced by a measuring means which consists of at least two accelerometers 32 for measuring longitudinal acceleration, which are arranged adjacent to the fixing point 21 of the trans- verse damping means m the carriage body.
- the accelerometers 32 provide information about the bending of the carriage body.
- the gyro 18 can be replaced by an accelerometer 34 arranged on the bogie.
- the gyro 18 can be replaced by a force- sensing device 33 m the transverse damping means 20, which measures the lateral motion of the bogie 5.
