Spherical surface
Web12. sep 2024 · The spherical coordinate system is defined with respect to the Cartesian system in Figure 4.4.1. The spherical system uses r, the distance measured from the origin; θ, the angle measured from the + z axis toward the z = 0 plane; and ϕ, the angle measured in a plane of constant z, identical to ϕ in the cylindrical system. Web13. dec 2016 · This work presents a theoretical model to research the vibration due to surface waviness of spherical roller bearings (SRBs), taking account of the self-aligning feature and the external axial load. The surface waviness is described by cosinoidal functions. The self-aligning features, including the variation law of the self-aligning …

Web25. jún 2024 · Our optical system employs a spherical mirror at an initial image plane that is created by a relay lens. The shape of the initial image surface is changed to a sphere by the curved mirror. We calculate the radius of the mirror by the Gaussian imaging equation. Then it is simulated by optical design software to evaluate the MTF.
