IngeniArts, a fast-growing start-up based in Quebec City, has developed a high performance energy storagesystem for industrial lifts. Their patented system combines a kinetic energy storage to chemical storage tosupport highly demanding application such as forklift and other type of lifting devices. This synergeticcombination offers fast response capability together with long autonomy. The mechanical energy storage,referred typically as a flywheel, however introduces vibrations in the system. While typical electric motorvibrations are well understood, there is limited scientific literature on IngeniArts specific configuration withhigh energy storage capacity.This project aims at developing an understanding of the rotordynamics of the flywheel in differentenvironmental conditions, and assess the high vibration seen in some cases. A model will be developed toevaluate the modal response and vibration amplitudes expected, which will be validated with experimentalresults. This model will allow to evaluate problematic vibration conditions, and propose design modification toavoid those high vibrations. A revised design will be fabricated and tested to assess the vibrations obtained.The results will provide IngeniArts with a better understanding of their technology and an improved version oftheir flywheel, which will lead to higher performance and wider implementation of this system into IngeniArtsproduct line.

IngeniArts是一家位于魁北克市的快速发展的初创企业，它为工业升降机开发了一种高性能的储能系统。他们的专利系统将动能存储与化学品存储相结合，以支持高要求的应用，如叉车和其他类型的起重设备。这种协同组合提供了快速响应能力和长期自主性。然而，机械能存储器（通常称为飞轮）在系统中引入振动。虽然典型的电动机振动是很好的理解，有有限的科学文献IngeniArts的具体配置与高能量存储capacity.This项目的目的是发展的转子动力学的飞轮在不同的环境条件下的理解，并评估在某些情况下看到的高振动。将开发一个模型来评估模态响应和预期的振动幅度，这将与实验结果进行验证。该模型将允许评估有问题的振动条件，并提出设计修改，以避免这些高振动。将制造和测试一个修改后的设计，以评估所获得的振动。结果将使IngeniArts更好地了解他们的技术和改进版本的飞轮，这将导致更高的性能和更广泛的实施，该系统到IngeniArts产品线。
