Passive Shock Isolation Utilising Dry Friction

Figure 22

Displacement response of the thin secondary beam system with intermediate friction. (a) Measured. Solid line: base input. Dashed line: response at the end of the primary beam (sensor 2). Dash-dotted line: response at the end of the secondary beam (sensor 3). Dotted line: response at the end of the secondary beam (sensor 4). (b) Simulation with intermediate Coulomb friction. Solid line: base input. Dashed thick line: primary mass response, . Dashed thin line: primary mass response, . Dash-dotted thick line: secondary mass response, . Dash-dotted thin line: secondary mass response, .
