众所周知,试验台试验是舵机制造的最后阶段。试验台试验的任务应是在最接近操作工况的条件下,考核舵机的承载能力。试验台借助于加载设备模拟舵机的工作负载。这种加载设备不仅能精确模拟舵机的工况,还应保证试验过程中能耗最小。在图1中,虚线表示由于水动力作用,舵杆上的力矩(M_m)与舵角(α)的标准函数关系,而实线则是考虑了舵杆轴承损耗后的力矩与舵角间的相互关系。图1a是表示普通舵和半平衡舵(M_m)与(α)的关系,而图1σ是表示平衡舵和主动舵的(M_m)与(α)的关系。箭头方向表
As we all know, test bench test is the final stage of steering gear manufacturing. The task of the test bench test should be to assess the carrying capacity of the steering gear at the closest operating conditions. The test rig simulates the work load of the steering gear with the aid of a loading device. This loading device not only accurately simulates the condition of the steering gear, but also ensures that the energy consumption during the test is minimized. In Figure 1, the dotted line indicates the standard function of the moment (M_m) on the rudder stock due to hydrodynamic forces and the rudder angle (α), while the solid line takes into account the relationship between the moment after rudder bearing loss and the rudder angle Interrelationship. Figure 1a shows the relationship between normal and semi-rudder (M_m) and (α), while Figure 1σ shows the relationship between (M_m) and (α) for balance rudder and aft. Arrow direction table
