In the era of digitalization, there are many emerging technologies, such as the Internet of Things (IoT), Digital Twin (DT), Cloud Computing and Artificial Intelligence (AI), which are quickly developped and used in product design and development. Among those technologies, DT is one promising technology which has been widely used in different industries, especially manufacturing, to monitor the performance, optimize the progresses, simulate the results and predict the potential errors. DT also plays various roles within the whole product lifecycle from design, manufacturing, delivery, use and end-of-life. With the growing demands of individualized products and implementation of Industry 4.0, DT can provide an effective solution for future product design, development and innovation. This paper aims to figure out the current states of DT research focusing on product design and development through summarizing typical industrial cases. Challenges and potential applications of DT in product design and development are also discussed to inspire future studies.

在数字化时代，物联网（IoT），数字孪生（DT），云计算和人工智能（AI）等许多新兴技术得到了迅速发展，并用于产品设计和开发中。在这些技术中，DT是一种很有前途的技术，已广泛应用于不同行业（尤其是制造业）中，以监视性能，优化进度，模拟结果并预测潜在的错误。在设计，制造，交付，使用和寿命终止的整个产品生命周期中，DT也扮演着各种角色。随着个性化产品需求的增长以及工业4.0的实施，DT可以为未来的产品设计，开发和创新提供有效的解决方案。本文旨在通过总结典型的工业案例，找出专注于产品设计和开发的DT研究现状。还讨论了DT在产品设计和开发中的挑战和潜在应用，以激发未来的研究。
