Problems solved by technology

[0021] ②The cost of structural technical services has increased sharply
[0022] It can be seen that due to the design defects of the German ICE3 bogie prototype, the passenger dedicated line is not a necessary and sufficient condition to ensure the stability and safety of high-speed rail.

Embodiment Construction

[0130] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0131] The present invention takes the ICE3 bullet train bogie as the technical prototype, such as figure 1 As shown, the structural diagram of the ICE3 bullet train bogie, in which, 1 is the motor and hanger; 2 is the following wheelset and positioning stiffness; 3 is the rail; 4 is the bogie frame; 6 is the bolster; 7 is the motor shock absorber, 2 for each frame; 8 is the elastic hanging plate, 4 for each frame; 9 is the guide wheel set and positioning stiffness.

[0132] Borrowing the form of anti-snake redundancy design, the present invention proposes the following figure 2 The combination of T60 and T70 is shown. In order to facilitate installation, the combined application of T60 and T70 should be unified in its installation form, such as T60 on top and ...

Abstract

The invention discloses a method for achieving an anti-snaking broadband energy absorption mechanism and an optimal configuration method for the parameters of a bogie. According to the method and the optimal configuration method, a dynamic design method is mainly applied, and lead-lag correction of unstable snaking oscillation phenomena of the bogie is achieved in a self-adaptive control manner; an anti-snaking redundant design form of an ICE3 prototype is borrowed, the anti-snaking broadband energy absorption mechanism is achieved through combination application of novel anti-snaking vibration reducers, and the method and the optimal configuration method are simple and applicable; and an anti-snaking soft constraint or anti-blocking technology is borrowed, the hydraulic rigidity is properly reduced, and rheology nonlinear influences are avoided. By means of the method and the optimal configuration method, the design defects of the ICE3 bogie prototype are overcome, a high-speed-rail passenger-dedicated development manner is gradually changed, and then the rate of return on investment is increased; in addition, the adaptability and the friendliness to track lines are improved, and the railway construction investment cost can be saved; and meanwhile the robustness of perturbation or disturbance of natural factors is improved, and particularly when the method and the optimal configuration method are used for mountain lines, and the structural technical service cost can be obviously reduced.

Description

technical field [0001] The present invention relates to the type selection and parameter configuration method of high-speed bogie anti-snake shock absorber, which adopts necessary technical measures to realize the anti-snake wide-band energy absorption mechanism, partially recovers the self-guiding ability of the bogie, and satisfies the cross-line application of long crossing roads Require. Specifically, the low-frequency structural damping and high-frequency impedance must form the complementarity of the two damping technologies, and then use the adaptive control method to realize the lead-lag correction of the bogie’s unstable hunting oscillation phenomenon, and overcome the existing high-speed The bogie is restrictive to the technical conditions of wheel fittings. Background technique [0002] From the point of view of high-speed train system integration, the high-speed bogie must adopt a dynamic design method, and use the anti-snaking broadband energy-absorbing mechani...
