摘要： A method for predicting fatigue life of a structure includes providing a finite element (FE) model of the structure; calculating a modal stress and a frequency response function (FRF) of the FE model; calculating a stress power spectral density (PSD) matrix; calculating a damage transformation matrix [A]; calculating a covariance matrix from the stress PSD matrix; determining angles θ, φ, and ψ in a plane with maximum equivalent variance based on the calculated covariance matrix; and calculating a variance—damage parameter with the angles θ, φ, and ψ incremented in a predetermined amount of degrees to thereby identify critical planes where a fatigue crack will occur in the structure.

摘要： A belt tensioner system for a belt starter generator has a first belt tensioner with a first fluid operated strut. A first arm is coupled with the first strut and has a pulley to tension a belt. A pivot fixes the first arm on the belt starter generator for pivotal movement so that the strut moves unidirectionally pivoting the first arm toward a first side of the belt to apply tension on the belt via the pulley. A second belt tensioner has a second fluid operated strut. A second arm is coupled with the second strut and has a pulley to tension the belt. A pivot for fixing the second arm on the belt starter generator for pivotal movement such that the second strut moves unidirectionally pivoting the second arm toward a second side of the belt to apply tension on the belt via the pulley.

摘要： A vehicle system for reducing vibrations on a vehicle includes an engine connected to an automatic transmission through a turbine of a torque converter clutch. A gearset is associated with the transmission and includes a sun gear, a ring gear and a pinion carrier. A gear clutch has a first clutch component fixed to a case of the transmission and a second clutch component fixed to the gearset. The first and second clutch components are configured to slip based on an enable condition being satisfied thereby mitigating vibrational modes experienced within the vehicle system.

摘要： A hybrid electric vehicle (HEV) includes an internal combustion engine, a motor/generator configured to drive the internal combustion engine or be driven by the internal combustion engine to generate electricity to charge a high voltage battery and/or drive one or more electric traction motors, and an exhaust aftertreatment system having a gasoline particulate filter (GPF). A control system includes a controller for monitoring and performing a regeneration operation of the GPF. The controller is programmed to determine the GPF needs to be regenerated, and operate the internal combustion engine in fuel shut-off to generate a flow of air to the GPF to initiate a GPF regeneration.

摘要： Control techniques for a fuel cell electrified vehicle (FCEV) involve an electrified vehicle control unit (EVCU) configured to control a set of primary operations of the FCEV, a fuel cell propulsion system (FCPS) configured to control a set of secondary operations of the FCEV, a controller area network (CAN) connecting the EVCU to the FCPS, and a set of hardwire wakeup lines connecting and configured to send a primary wakeup signal from the EVCU to each of the FCPS and a battery pack control module (BPCM). The EVCU selectively communicates a secondary wakeup signal to the FCPS via the CAN, and wherein the FCPS is woken up in response to receiving both the primary and secondary wakeup signals via the hardwire wakeup lines and the CAN, respectively, to prevent wakeup of the FCPS during a set of wakeup operations in which the FCPS is not required.
