摘要： A computer of an active vibration damping device calculates operation command values for an actuator from rotation information of a drive source, and corrects the operation command values in accordance with an internal temperature of the actuator. The computer applies a drive voltage to the actuator using a voltage duty ratio based on the corrected operation command values. The computer also estimates the internal temperature on the basis of an average duty ratio as an average of the voltage duty ratios in a predetermined interval.

摘要： A damper assembly includes a housing that defines an interior chamber. A rod is supported by the housing, and is at least partially disposed within the interior chamber. A piston assembly is attached to the rod within the interior chamber. The piston assembly separates the interior chamber into at least a first fluid chamber and a second fluid chamber. The piston assembly includes an annular plate defining at least one orifice, which interconnects the first fluid chamber and the second fluid chamber in fluid communication. The piston assembly includes at least one valve disc that is disposed adjacent a first face of the annular plate. An SMA device is disposed in contact with the valve disc. The SMA device is changeable between a first state and a second state, at a transition temperature, to control a bending stiffness of the valve disc to adjust a damping rate.

摘要： A dipper assembly for a mining shovel includes a dipper body, a dipper door pivotably coupled to the dipper body, an arm, a housing coupled to one of the body and the door, and a piston. The arm includes a first end pivotably coupled to the body and a second end pivotably coupled to the door. The movement of the door relative to the body drives the arm to pivot relative to the body. The housing includes an inlet in fluid communication with a fluid source, an outlet, and a cylinder partially defining a pump chamber in fluid communication with the inlet and the outlet. The piston is movable within the cylinder and biased in a first direction. The pivoting movement of the arm causes the piston to move in a second direction opposite the first direction. The movement of the piston changes a volume of the pump chamber.

摘要： A thermally driven piston assembly's housing has (i) a first material slidingly fitted therein, and (ii) at least one plug of a second material slidingly fitted therein and abutting the first material. The first material is one (e.g., a liquid crystal elastomer) that undergoes a stiffness change and/or a dimensional change when subjected to a temperature change in the temperature range of interest. When subjected to the temperature change while in the housing, the first material is restricted to changing dimensionally along a single dimension. The second material retains its shape and size throughout the temperature range of interest. As a result, the plug moves in the housing in correspondence with the dimensional change of the first material or the plug's movement is damped by the stiffness change of the first material.

摘要： A passive gas spring disposed within a fuel cell assembly adjacent a fuel cell stack for maintaining the stack under compression at elevated temperatures. The spring includes at least one membrane formed of a metal alloy stable at the operating temperatures required of the fuel cell assembly. The membrane closes a chamber for retaining an amount of gas. As temperature of the assembly changes, differential thermal expansion of fuel cell components and supporting structural elements can cause height mismatches between the stack and the supporting structure, otherwise resulting in a loss of compression in the assembly. Because the temperature of the gas also increases, however, the spring force of the gas spring increases, thereby maintaining compressive load on the various assembly seals. A mechanical spring may also be provided.
