[. . . ] Each unit is used to suppress vibration in the direction along the axis of the main cylindrical section. The operating frequency of an individual unit can be adjusted and set before installation over a frequency range of about 2. 5-to-1. The products are specified by the nominal primary resonance frequency. For example, TMD1-150 is a 150 Hz unit with approximately one pound moving mass. The broader frequency range for each model (greater than 8-to-1) is achieved during assembly and results in small variations in the installed height and mass. Each TMD model has a standard mechanical interface via a single threaded rod or bolt. [. . . ] · Mountain View, CA, 94043 · 650-210-9000 · Fax 650-210-9001 · www. csaengineering. com [. . . ]
