|
With the SMP vacuum vessel now installed inside the shield box, a test was performed to measure the torque required to rotate the vessel. At a
moment arm distance of 2.0m a force of 89N was required to rotate the vessel (with no module installed) resulting in a torque of 178Nm. Based on
this, the coefficient of rolling resistance (CRR) was calculated to be 0.007; This is fairly close to available data for similar applications such |
