在测定工程机械工作装置切削阻力时,我们应用了八角形二维测力传感器。该传感器能够同时测量作用在工作装置纵向对称平面内的水平分力Fx、垂直分力Fz和弯矩My,从而能够很方便而准确地确定作用在工作装置上切削阻力的大小、方向和作用点。由于大多数土方机械工作装置如推土板、平地铲、装载机和铲运机的铲斗等,其高度和深度远较宽度为小,而其工作阻力,在一般情况下,可以认为沿宽度是不变的。由于这一特点,在测定它们的工作阻力时,可将其简化为平面问题。在这种情况下,应用八角形二维测 In measuring the cutting resistance of construction machinery work equipment, we applied an octagonal two-dimensional force sensor. The sensor can simultaneously measure the horizontal component force Fx, the vertical component force Fz and the bending moment My in the longitudinal plane of symmetry of the working device, so that the size, direction and action point of the cutting resistance acting on the working device can be conveniently and accurately determined. . Because most earth-moving machinery work devices such as bulldozers, leveling shovels, loaders, and shovels of scrapers, their height and depth are much smaller than the width, and their working resistance, in general, can be considered along the width It is unchanged. Due to this feature, in the determination of their working resistance, it can be simplified as a planar problem. In this case, apply octagonal two-dimensional measurement
