  • Patent number: 12197531
    Abstract: The invention concerns a method for determining a mechanical stress of a runner (40), of a hydraulic machine (10), wherein the runner is arranged to rotate around a rotation axis, wherein the hydraulic machine comprises a hydraulic channel delimited by hydraulic surfaces of the runner, the hydraulic surfaces being the surfaces against which a stream of water exerts the forces when the runner is driven in rotation by said stream of water, wherein the runner further comprises a sensor (G) on protected areas positioned away from the hydraulic channel, the method comprises the steps of: a) collecting a physical quantity measured by the sensor (G), b) determining a mechanical stress on a specific location of the hydraulic surface, via a transfer function that correlates the physical quantity measured in step a) and said mechanical stress on the specific location.

  • Publication number: 20240167490
    Abstract: The invention concerns a method for detecting a fatigue undergone on at least one specific location of a hydraulic unit (10), the method being characterized in that the fatigue undergone on the at least on specific location is detected by at least one fatigue indicator (F) said at least one fatigue indicator arranged for being remotely queried via wirings or via a wireless connection.

  • Publication number: 20090033057
    Abstract: A vehicle comprising a variable-camber suspension device, the suspension device (1) allowing a substantially vertical suspension movement and a camber movement of the wheel (2) with respect to the body (5) of the vehicle, the vertical suspension movement and the camber movement being substantially independent. The suspension device is connected to the body by connection means (6, 7) allowing a rotation (?) of the suspension device with respect to the body about a transverse axis of rotation.

  • Publication number: 20060099667
    Abstract: The present invention relates to a method for performing restrained dynamics docking of one or several substrates having allosteric or synergistic effect on enzymes presenting multipspecific and flexible active site. It also concerns a method for determining the 3D-substrates, which is the case for multispecific enzymes such as cytochrome P450, and specifically to cytochrome P450 3A4 and P450 3A7.

  • Publication number: 20050179225
    Abstract: The invention concerns a suspension system (1) designed to connect a wheel support (3) to a vehicle body (5), the said system comprising means (4) that confer on the wheel support, relative to the body, a degree of camber freedom and a degree of freedom of the vertical deflection of the suspension which are independent of one another, the said suspension system comprising an anti-roll device capable of controlling the roll of the body, the said anti-roll device being in addition arranged such that it influences the camber variation as a function of the difference between the vertical deflection of the said wheel relative to that of the opposite wheel on the same axle.

  • Publication number: 20050051976
    Abstract: In a suspension system that connects a wheel support to a vehicle body, the wheel support is designed to carry a wheel of radius “r”, the wheel is intended to rest on the ground via a contact area, the system includes an arrangement that confers upon the wheel support, relative to the body, a degree of freedom of the camber and a degree of freedom of the deflection of the suspension that are independent of one another. The system is configured such that the camber movement of the wheel support relative to the body has, around a mean position, an instantaneous center of rotation (CIR r/c) located within a range from 2.5 r above ground to r below ground.
