  • Patent number: 12222015
    Abstract: A hydro bushing includes an outer pipe, an inner pipe disposed within the outer pipe and spaced apart from the outer pipe, an elastic body disposed between the outer pipe and the inner pipe and provided with a liquid chamber portion accommodating liquid therein, and a nozzle disposed between the outer pipe and the elastic body and including a stopper extending toward the liquid chamber portion such that a portion of an internal surface of the nozzle protrudes to be in contact with the liquid chamber portion. A contact end of the stopper is formed to have a surface corresponding to deformation of the elastic body caused by conical movement.

  • Publication number: 20250001995
    Abstract: A degradation level of a noise source is predicted by performing deep learning using frequency data indicating a vibration of the noise source during a time period and degradation data indicating degradation of the noise source during the predetermined period to determine a state estimation model. First vibration signals are measured at the noise point during a monitoring period. The first vibration signals are converted into a frequency domain, and the frequency domain converted first vibration signals are input into the state estimation model to estimate time series degradation data of degradation of the noise source during the monitoring period. A degradation prediction model is determined by deep learning using the time series degradation data. Degradation data indicating predicted degradation of the noise source during a prediction period are predicted via the degradation prediction model. A remaining useful life of the noise source may be calculated.

  • Publication number: 20240393167
    Abstract: Noise point data is generated by converting a vibration signal, measured at a source (noise point) of the vibration signal at a first time, into a frequency domain. Sound point data is generated by converting the vibration signal, measured at a sound point (different from the noise point) at the first time, into a frequency domain. Deep learning is applied to the noise point data and the sound point data to generate a noise prediction model for predicting frequency data of a vibration at the noise point using frequency data indicating a vibration at the sound point. The noise prediction model is applied to target vibration signal, measured at the sound point at a second time, to predicting target noise point data indicating vibration at the noise point. The predicted target noise point data is used to diagnose a fault at the noise point.

  • Patent number: 11453262
    Abstract: A void bush for a vehicle suspension includes: inside bumps formed in an inside stopper and outside bumps formed in an outside stopper. In particular, the inside bumps and the outside bumps are configured to cross perpendicularly to each other to allow the inside bumps and the outside bumps to be brought into point-contact with each other during behavior of the suspension. The inside bumps are not arranged in parallel to each other and the outside bumps are not arranged in parallel to each other. Accordingly, contact area between the inside bumps and the outside bumps is greatly reduced and contact abrasion positions therebetween are diversified so that durability and lifespan of the void bush are improved.

  • Patent number: 10792968
    Abstract: A bushing may include an elastic compression portion configured to form a primary compression ratio due to a compressive deformation by a primary press-fitting load and be pressed by a secondary compression ratio greater than the primary compression ratio by a secondary press-fitting load greater than the primary press-fitting load, wherein the elastic compression portion is formed in an opened cross section to be a secondary surface contact larger than a primary surface contact without a bulge phenomenon by a volume dispersion in a state in which it is pressed by the primary press-fitting load to be the primary surface contact and then is pressed by the secondary press-fitting load.
