机械系统在运行过程中几乎不可避免地会在某个点发生故障。这可能是由于预先存在的设计缺陷或使用过程中的一些意外损坏。无论进行多少规划和故障分析,都不可能创造出完全可靠的机器。提高可靠性的现有方法通常涉及建模和检测方面的进步,以包括克服特定故障或减轻其影响的特定机制。虽然这对延长机器的使用寿命大有帮助,但系统的整体复杂性也大幅提高,预测和解释所有可能的故障模式变得越来越困难。提出了一种新的设计理念,允许系统重新配置自己以克服故障,而不是专注于减轻或降低故障的概率,从而产生自我修复的设计。这种方法在一个自校正四杆机构的设计中得到了验证.
Mechanical systems will almost inevitably fail at some point during operation. This can either be due to a preexisting design flaw or some unexpected damage during usage. No matter how much planning and fault analysis is performed it is impossible to create a perfectly reliable machine. Existing approaches to improving reliability normally involve advances in modeling and detection to include specific mechanisms to overcome a particular failure or mitigate its effect. Whilst this has gone a long way to increasing the operational life of a machine, the overall complexity of systems has improved sharply and it is becoming more and more difficult to predict and account for all possible failure modes. Rather than focusing on mitigating or reducing the probability of failure, a new design philosophy is proposed that allows systems to reconfigure themselves to overcome failure – thus yielding a self-healing design. This approach is demonstrated in the design of a self- rectifying 4-bar linkage mechanism.
