The Challenge
Segway LLC, the company behind the innovative Segway Human Transporter (HT), faced significant engineering challenges in the development of their product. The Segway HT, a two-wheeled, self-propelled scooter, was designed to revolutionize personal transportation. However, the device's compact design required the integration of numerous hardware and software components into a small space. This complexity presented significant challenges for the Mechanical Integrity group at Segway, who were tasked with ensuring that the device's features and functionality conformed to specified performance criteria. The group faced particular difficulties with the Segway HT's chassis, which had to accommodate the weight of an operator up to 250 pounds, house the device's motors, batteries, and electronic components, and be lightweight. The complex geometric configurations of the design made standard mechanical analysis techniques ineffective or extremely difficult to conduct.
About The Customer
Segway LLC is an American manufacturer of two-wheeled, self-balancing personal transporters, famously known for the Segway Human Transporter (HT). The company was founded by entrepreneur Dean Kamen with the vision of revolutionizing personal transportation. The Segway HT, the company's flagship product, is a self-propelled scooter designed to imitate the human body's ability to maintain balance. The device is intended to be a common sight on urban sidewalks around the world, offering an alternative to traditional modes of transportation. The company works closely with design engineers and has a dedicated Mechanical Integrity group to ensure the performance and integrity of their products.
The Solution
To overcome these challenges, Segway utilized ANSYS Multiphysics software, which had previously been instrumental in realizing other innovative products at DEKA Research and Development Company, from which Segway was spun off. The software was used to analyze the geometric nonlinearities present in the various design elements of the Segway HT's chassis. Analyst Mark Wyer used ANSYS Multiphysics for stress and fatigue analyses of the Segway HT's numerous components and assemblies. The software was able to predict the location of stress/fatigue 'hot spots' on numerous areas of the Segway HT, including the load conditions the Segway's wheels would see in regular usage. These predictions were verified via physical tests on a specially designed fatigue-testing machine developed by the team.
