Abstract: The development of bus-structure for the further GEO satellite is described. The target of the further GEO satellite is to be the satellite with 8 kW solar generation, 3650 kg launch weight, and sufficiently global competitiveness on the next decade. The target weight of the bus-structure is lower than 215 kg (lower than 5.9 % of launch weight). The design and mechanical tests of the bus structure have been successfully completed.

The major aim of this paper is to derive simple closed-form solutions which can be easily calculated using spreadsheet software, for thin anisotropic cylinders under torsion, axial compression and combined loads that include the effect of layup anisotropy. Previously derived partial differential equations of equilibrium that are solved by including layup anisotropy but neglecting transverse shear deformation and closed-form solutions are obtained. One of the three solutions satisfies a simply supported condition, another a fully fixed condition, and both of these can be applied to cylinders that are shorter and longer than the length of the bending boundary layer. The third solution is called the bending boundary layer solution, and it can only be applied when the cylinder is longer than the length of the bending boundary layer. In addition, guidelines for dividing mesh in finite element analyses of anisotropic cylinders are discussed in terms of the precision of the bending stress on the edge. A comparison of the closed-form solution and the precise solution including both layup anisotropy and transverse shear deformation shows that differences appear only on the bending-boundary layer, the differences increase with the radius to thickness ratio decreases, and the closed-form solution gives a safe-side estimate for design purposes.

Methods of evaluating the one-sided tolerance limit (A-and B-basis values) of combined sample sets are derived. The A-and B-basis values are statistically calculated numbers that respectively indicate that at least 99 and 90 percent of the population is expected to equal or exceed the statistically calculated value with a confidence of 95 percent, and they are used to determine strength tolerance limits in aerospace designs. The A-and B-basis values tend to be underestimated when the sample size is small and the conventional methods are used. Our novel methods improve the basis values by combining multiple sample sets from normally (Gaussian) distributed populations. We extended analysis of variance (ANOVA) to evaluate the A-and B-basis values by using non-central t-distribution under the condition of equality of variances. In addition, we derive coefficients for the basis values under the condition of non-equality of variances by using a Monte-Carlo method. Numerical examples show that both methods, i.e., equality and non-equality of variance cases, increase the A-and B-basis values.
