摘要： The present disclosure provides a fatigue management system capable of managing fatigue of each portion of a construction machine more accurately than conventional systems. The fatigue management system S includes: a stress calculation section S1 that calculates stress acting on a plurality of portions of the construction machine based on the output of a sensor 18 attached to a part of the construction machine; a damage degree calculation section S2 that calculates the cumulative damage degree of each portion of the construction machine based on the stress calculated by the stress calculation section S1; and an index value calculation section S3 that calculates a fatigue index value, which is a weighted value of the cumulative damage degree, for each portion.

摘要： A swinging pinion on the side of an upper swing structure is meshed with a ring gear which is provided on and around the inner periphery of an inner ring on the side of a vehicular base carrier. A grease bath is provided on the inner side of the inner ring and under a swing frame. A center joint is located in an opening which is provided in the swing frame at the center of swinging motions of the upper swing structure. The grease bath is formed by bath-forming walls around an central top plateau wall which is connected the center joint on the inner peripheral side. An annular seal member of resilient material is interposed between the top plateau wall of the grease bath and the lower side of the swing frame. The annular seal member is formed in a height which is larger than the width of spacing between the top plateau wall and the swing frame. At one side, the seal member is detachably fixed either on the side of the swing frame or on the side of the top plateau wall section. At the other side, the seal member is provided with an annular sliding portion which is held in sliding contact with the other one of the swing frame and the top plateau wall in an inclined posture in a radially inward direction.
摘要翻译： 在上摆动结构侧的摆动小齿轮与设置在车辆基座的侧面上的内圈的内周侧的环形齿轮啮合。 在内圈的内侧和摆动框架下设置润滑脂。 中心接头位于在上部摆动结构的摆动运动的中心处设置在摆动框架中的开口中。 油浴是通过围绕中心顶部平台壁的浴形成壁形成的，中心顶部平台壁连接在内周侧的中心接头。 弹性材料的环形密封件介于润滑脂的顶部平台壁与摆动框架的下侧之间。 环形密封构件形成为比顶部平台壁和摆动框架之间的间隔宽度大的高度。 在一侧，密封构件可拆卸地固定在摆动框架的侧面或顶部平台壁部分的侧面上。 在另一侧，密封构件设置有环形滑动部分，其在径向向内的方向上以倾斜姿势与摇摆框架和顶部平台壁中的另一个滑动接触。

摘要： Provided is a movement identification device capable of identifying a specific motion of a construction machine based on the output of a sensor attached to the construction machine with higher accuracy than the conventional technology. A movement identification device 100 includes a waveform generation unit 111, a waveform storage unit 121, and a motion identification unit 112. The waveform generation unit 111 generates a force waveform based on the signal of a force sensor that detects the force acting on the construction machine and an attitude waveform based on the signal of an attitude sensor that detects the attitude of the construction machine. The waveform storage unit 121 stores reference waveforms, which are combinations of force waveforms and attitude waveforms corresponding to specific motions. The motion identification unit 112 compares a motion waveform, which is a combination of a force waveform and an attitude waveform corresponding to an arbitrary motion of a construction machine, with the reference waveforms stored in the waveform storage unit 121 to identify a specific motion in the arbitrary motion of the construction machine.
