目前的电子汽车衡秤台,是以刚度作为主要设计依据,以简支梁作为计算模式,其中间为槽钢,上、下两面焊以铁板。这样形式的秤台,一是自重较重,增加了秤的制造成本;二是秤台在传感器支承处的转角将随称量的不同而发生变化,是计量误差的来源之一。 图1所示为原设计模式。针对上述问题,笔者对原来的秤台设计模式进行了改进。改进后的模式示于图2。只要合理地设计两梁的柔度,秤台在传感器支承处的转角θ将能得到一定程度的补偿。由于不再强调以刚度 The current electronic truck scale platform is based on the stiffness as the main design basis, as a simple beam mode of calculation, the middle of the channel, the upper and lower sides of the welded iron. This form of weighing platform, one heavier weight, increasing the cost of manufacturing scales; the second platform weighing sensor at the bearing angle will vary with the weighing is one of the sources of measurement error. Figure 1 shows the original design mode. In response to the above problems, the author of the original scale platform design patterns were improved. The improved model is shown in Figure 2. As long as the flexibility of the two beams is designed reasonably, the rotation angle θ of the weighing platform at the sensor support point will be compensated to a certain extent. Because no longer emphasize stiffness
