Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision
|
SMP drivetrain design work is currently underway. Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm). The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp |

|
On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in
the ISAC-1 Experimental Hall. Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was
lowered down the hatch to the B2 level. The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed. The |

|
Dragan Mitrovic, TRIUMF structural engineer, was consulted earlier this week regarding seismic requirements for the SMP assembly. Installation
location, overall dimensions, total weight, and the center of mass for assembly IRH1670 were provided to him by e-mail. On Feb 20th he communicated
verbally that he had analyzed the assembly for seismic loads, and concluded that this equipment does not require anchoring or any other form of seismic |

|
Last week drilling of the additional required holes in the SMP shield box was completed in the Target Hall. This morning the shield box (IRH1675)
was moved to its final installation position in the silo area on the B2 level. The vacuum vessel (IRH1806) was then installed inside the shield box.
The center of the vacuum vessel is 2-3" north of the south travel limit of the crane. Photos as well as measurements of the final position are |

|
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 |
