| Abstract | This report complements a broader analysis of a novel cryogenic suspension system incorporating blade springs. These blades introduce vertical compliance in a test-mass suspension system with flexures and suspension beams under compression and tension respectively, compensating for manufacturing variations, as well as incorporating a means of providing vertical thermal noise attenuation. Designed with an isosceles triangular shape for uniform bending, the blades attach at an angle, with a pre-bent tip so that the area on which the load is supported lays horizontal. Through FEM simulations using Ansys, we identified a configuration in which we can base our future studies, with a 10.5 mm thickness, a 13.63 m curvature radius, and a base tilt of 12.453 mrad, ensuring a maximum surface tensional stress of 52.69 MPa—maintaining a safety factor close to 3. |
