接下去按照表1数据编制包括各级段加载时间的加载图。为了考虑峰值载荷(过渡工况),将等於电动机最大转矩M_L级段附加到已求得的加载图中。因为过渡工况的相对时间t_L很短,所以载荷M_L不需要在每个加载周期中都加载,而要经过几个加载周期后再加。例如采煤机传动装置寿命试验时,载荷M_L应当经过6个周期(经过60h),加载1min。
Followed in accordance with the data in Table 1 preparation load map at all levels of loading time. In order to consider the peak load (transitional condition), a section equal to the maximum motor torque M_L is added to the load map that has been found. Because of the short time t_L for the transitional condition, the load M_L does not need to be loaded during each load cycle, but only after a few load cycles. For example, shearer drive life test, the load M_L should be after 6 cycles (after 60h), load 1min.
