Abstract: Disclosed are an apparatus and a method for actively reducing an action impact of an excavator, and an excavator, which are related to the technical field of engineering vehicles. The method includes: collecting a boom inclination angle, a stick inclination angle, a bucket inclination angle, and state information of an operating lever, of the excavator; determining operation information of the operating lever, and judging whether the boom inclination angle, the stick inclination angle, and the bucket inclination angle are within set ranges; and controlling, based on a judgment result, operating states of an electronically controlled main valve and a main pump of the excavator. The method may reduce impact and vibration generated during operation of the excavator, thereby reducing a failure rate, and improving service life and work efficiency.

Abstract: Disclosed is an adaptive control method applicable to an excavator. The adaptive control method includes: acquiring detection parameters of the excavator, the detection parameters comprising a displacement of an electric control handle of the excavator and angle information of the excavator; identifying a current working condition of the excavator based on the detection parameters; and adjusting control parameters of the excavator based on the current working condition. According to the adaptive control method provided by the present disclosure, the current working condition is identified by using the displacement of the electric control handle and the angle information of the excavator, and then the control parameters of the excavator are adjusted based on the current working condition, so that the control parameters are automatically adjusted with change of the current working condition, which improves control efficiency of the excavator.

Abstract: A road surface self-adapting anti-slip anti-lock control method for an electrically driven mine vehicle comprises the following steps: if the vehicle is in drive mode, judging whether the speed of a designated driving wheel and the slip ratio of said wheel are greater than the corresponding preset value; exiting, if any of the two judging results is negative; if the speed of the vehicle is more than a first preset value, adjusting the torque of the designated driving wheel according to a high speed anti-slip policy, if not, according to a low speed anti-slip policy; judging whether the speed of the vehicle and the slip ratio of the designated drive wheel are more than the corresponding preset value in brake mode, thereby determining whether the anti-lock strategy is carried out. The control method is simple, is low in cost, and is convenient to debug on the mine vehicle.

Abstract: An excavator self-detection system comprises a controller, a fuel inlet flow meter, a fuel outlet flow meter and a performance self-detection controller. The fuel inlet flow meter and the fuel outlet flow meter are deployed at a fuel inlet and a fuel outlet of an engine respectively, and are connected to the performance self-detection controller. The performance self-detection controller is connected to the controller. The performance self-detection controller reads the signal values of the fuel inlet flow meter and the fuel outlet flow meter, calculates a fuel consumption value, and reads a machine parameter of the excavator through the controller to determine the performance. A detection method is also provided which uses the above excavator self-detection system. The method comprises performance self-detection, a fuel consumption test, and an efficiency test. The measuring equipment can be set by itself according to different machine types and different communication protocols.
