Study on Fatigue Life of Spring Bracket for Air Suspension System
In order to research the fatigue life characteristics of the pivotal load carrying structure equalizing beam of a heavy-duty truck, a fatigue damage simulation calculation method is presented based on the digital proving ground. The typical proving ground durability virtual digital pavement is built by the ADAMS, with the simulation and pavement test should obtain the dynamic load of the equalizing beam in the running state, LMSTecWare software is used to calculate fatigue damage of the pivotal load carrying structure. The contrast results of simulation and test indicate that the simulation results of the cumulative fatigue damage of the equalizing beam coincide with the pavement test very wel1, and the method can be use to carry out the fatigue life simulation and the fatigue life prediction of the pivotal structure of the heavy-duty truck, and reduce the new product development period and reduce the development cost.
