The 6th Joint International Conference on Multibody System Dynamics (IMSD) and the 10th Asian Conference on Multibody Dynamics (ACMD) are two prestigious conferences being organized to bring together researchers, professionals, and students actively working in the area of multibody system dynamics. The IMSD conference is the sixth in the series after Lappeenranta in 2010, Stuttgart in 2012, Busan in 2014, Montreal in 2016, and Lisbon in 2018. Asian countries also host to ACMD conferences held in the past in Iwaki in 2002, Seoul in 2004, Tokyo in 2006, Jeju in 2008, Kyoto in 2010, Shanghai in 2012, Busan in 2014, Kanazawa in 2016, and Xi’an in 2018. These two biannual conferences are being held as a joint event at New Delhi, India during 16-20 October 2022. Our plans to hold this conference in 2020 got postponed due to the Covid pandemic. In 2022, it is a very unique opportunity for the multibody system dynamics community to exchange ideas and make long-lasting contacts during this blended conference. Multibody dynamics studies formulation and solution of dynamics of various systems in the area of vehicle dynamics, aerospace engineering, biomechanics, virtual prototyping, machine design and many other areas of application. The demand for efficient and accurate solutions to the engineering problems posed by the industry provoke the need for active research in the area of real-time simulation capabilities, highly non-linear control devices, workspace and path planning, active control of machine flexibility and multidisciplinary features The purpose of the conference is to serve as a meeting point for the international multibody community from both academia and industry and thus provide a forum in which the recent developments in the field of multibody systems are discussed. We hope that you feel rewarded for your participation in IMSD-ACMD and that it will be a reference in your scientific activities. Welcome to New Delhi (India) for the 6th Joint Conference on Multibody System Dynamics and 10th Asian Conference on Multibody Dynamics. Subir Kumar Saha and Rama Krishna K New Delhi, October 2022.
