  • Comparative study on optimum design of rolling

    2015-12-1 · Chakraverty et al. had designed a constraint optimization problem of ball bearing with five design variables by using GA based on the requirement of long fatigue life. The authors presented the optimum design parameters and dynamic capacity of different bearing boundary dimensions. However, the constraints considered appear to be unrealistic.

  • A multi objective optimum design approach for rolling ...

    2018-3-19 · Minimum weight, Long fatigue life and adequate film thickness are some of the key design objectives in the optimum design of rolling element bearing (REB). The design approach by considering bearing envelop, fatigue life and wear life results in a low cost bearing. So a multi-objective constrained optimum design of deep groove ball bearing is proposed in this study.

  • A new fatigue damage accumulation rating life model

    The optimum preload for ball bearing is defined. When considering time-varying vibration load in fatigue damage accumulation rating life model, the optimum preload of bearing is larger than that without considering time-varying vibration load. The optimum preload has an obvious influence on fatigue life.
