The 45 Damped Rod is the most sophisticated rod available for critical applications where acoustical and vibrational forces are a concern. These rods incorporate cylindrical masses constrained by damping layers, concentrated in the upper portion of the rod where they are most effective in dissipating vibrational energy. This construction is the result of extensive computer modeling, dynamic testing and structural analysis. Newport’s patented internal damping system provides unmatched vibrational immunity. Compared to the best alternative designs, Newport damped rods exhibit 60% higher resonant frequency, 100% faster vibration decay and 160% better peak compliance. These 14 in. (356 mm) long rods mount to tables and breadboards with four bolts through a special ring base. Model 75 has a nylon gear rack for rack-and-pinion control over component elevation.


45阻尼杆是最复杂的杆可用的关键应用，其中声学和振动力是一个问题。这些杆包含受阻尼层约束的圆柱形质量，集中在杆的上部，在那里它们最有效地耗散振动能量。这种结构是广泛的计算机建模、动态测试和结构分析的结果。纽波特专利的内部阻尼系统提供了无与伦比的振动免疫力。与最好的替代设计相比，新港阻尼杆表现出60%更高的谐振频率，100%更快的振动衰减和160%更好的峰值顺应性。这些14。(356毫米)长杆安装在桌子和面包板与四个螺栓通过一个特殊的环基地。75型有尼龙齿条齿条和小齿轮控制组件的高度。
