Space Station Alpha Joint Bearing
نویسندگان
چکیده
Perhaps the most critical structural system aboard the Space Station is the Solar Alpha Rotary Joint which helps align the power generation system with the sun (Figure 1). The joint must provide structural support and controlled rotation to the outboard transverse booms as well as power and data transfer across the joint. The Solar Alpha Rotary Joint is composed of two transition sections and an integral, largediameter bearing. Alpha joint bearing design presents a particularly interesting problem because of its large size and need for high reliability, stiffness, and on-orbit maintainability.

Decompression sickness during simulated extravehicular activity: ambulation vs. non-ambulation.
BACKGROUND Extravehicular activity (EVA) is required from the International Space Station on a regular basis. Because of the weightless environment during EVA, physical activity is performed using mostly upper-body movements since the lower body is anchored for stability. The adynamic model (restricted lower-body activity; non-ambulation) was designed to simulate this environment during earthbo...
متن کاملNumerical Optimization Design of Anchoring End of Prestressed Cable at Some Hydropower Station
The paper discusses the numerical optimization design of anchoring end of prestressed cable at some hydropower station. There are two types of designing for the anchoring end, namely using square thick steel anchor bearing plate or using the roundtower anchor bearing plate. By the numerical calculation, the anchoring end using the round-tower anchor bearing plate can match the space and mechani...

متن کاملRadiographic measurement of joint space height in non-osteoarthritic tibiofemoral joints. A comparison of weight-bearing extension and 30 degrees flexion views.
There have been many reports which suggest that in patients with tibiofemoral osteoarthritis, a reduction in joint space is demonstrated better on weight-bearing radiographs taken with the knee in semiflexion than in full extension. The reduction has been attributed to the loss of articular cartilage in the contact area in a semiflexed arthritic knee. None of these studies have, however, includ...
متن کامل[Rosenberg projection for the radiological diagnosis of knee osteoarthritis].
BACKGROUND Knee osteoarthritis is highly prevalent in our country. An early diagnosis is very important to provide an accurate and early treatment, and eventually delay its progression. AIM To compare the diagnostic yield for osteoarthritis of two projections in knee X ray examination. MATERIAL AND METHODS We evaluated 44 knees with conventional (AP weight-bearing, in full extension) and Ro...
