如今，人的安全性和舒适性是车辆设计和制造中最重要的参数，这就是为什么每个组织都要确保车辆中使用的部件的质量和可靠性。钢板弹簧也是汽车的重要部件，对人体的安全性和舒适性起着重要的作用。它作为一个结构构件和悬挂系统的一个组成部分。钢板弹簧对汽车的功能性和安全性具有重要意义，因此，在钢板弹簧的设计和制造过程中，消除钢板弹簧的失效是非常重要的。在这项研究中，失效模式和影响分析已被用于分析和降低可能发生在汽车钢板弹簧的42个故障的风险。它从确定，分类和分析所有潜在的故障开始，然后用帮助数字分数对其进行评级。四个数字评分，即严重性，发生率，检测和风险优先数（RPN）用于发现半椭圆形钢板弹簧的高潜在故障。最后，针对RPN大于250的情况，提出了相应的措施，以提高产品的质量和可靠性。
Nowadays human safety and comfort are the most considerable parameters in designing and manufacturing of a vehicle, that is why every organization ensures the quality and reliability of components used in the vehicle. Leaf spring is also a component of vehicle which plays an important role in human safety and comfort. It acts as a structural member and an integral part of suspension system. It is important to eliminate the failures in designing and manufacturing process of leaf springs because of its importance in functionality and safety of vehicle. In this research, failure mode and effects analysis has been used to analyze and reduce the risks of 42 possible failures that can occur in automotive leaf spring. It starts from determining, classifying, and analyzing all potential failures and then rating them with the help numeric scores. The four numeric scores namely severity, occurrence, detection, and Risk Priority Number (RPN) are used to find the high potential failures of semi-elliptical leaf springs. In the end, actions are recommended for RPN greater than 250, to increase quality and reliably of product.
