Abstract:
A swing drive system for a construction machine enhances safety for an operator. A swing control means 55A has a lever input amount-torque table 11 and an actual rotating speed-torque table 13. Based on a lever input amount and an actual rotating speed of an electric motor, the tables are used to derive torque values. A minimum value of the torque values is taken as the acceleration torque. The swing control means 55A further has a lever input amount-meter-out restriction area table 15 and an actual rotating speed-relief torque table 119. Based on the lever input amount and the actual rotating speed of the electric motor, a meter-out restriction area is derived from the lever input amount-meter-out restriction area table and the actual rotating speed to calculate a meter-out torque. A minimum value of the meter-out torque and relief torque is taken as the braking torque.
Abstract:
A drive system of an electrically driven dump truck is capable of achieving an operational feeling in which the operation amount of the accelerator pedal is well balanced with the output horsepower of the electric motors, particularly at the time of slow traveling. To achieve this, the target motor output horsepower Pm0 corresponding to the operation amount of an accelerator pedal 1 is calculated. The target motor torque Tr1R, Tr1L is calculated on the basis of the target motor output horsepower Pm0 and the rotational speed ωR, ωL of electric motors 12R, 12L respectively. The acceleration torque limit values of the electric motors 12R, 12L corresponding to the operation amount of the accelerator pedal 1 are calculated, respectively. Then, smaller values are selected, as motor torque instruction values TrR, TrL, between the acceleration torque limit value and the target motor torque Tr1R, Tr1L to control inverters 73R, 73L, respectively.

Abstract:
A device testing apparatus including a connection terminal to which an electronic device under test is detachably attached, a pusher for pushing the electronic device in the direction of the connection terminal so as to connect the electronic device to the connection terminal, and a cooling unit for cooling the electronic device. As the cooling unit, an element cooling the device using electricity is for example used. The cooling unit includes a cooling medium blower for blowing a cooling medium around the electronic device and heat exchange projections or depressions for raising the cooling efficiency by blowing a cooling medium. In the device testing apparatus, even if the electronic device generates heat on its own during testing, the electronic device is cooled through the pusher, connection terminals, or socket, so the effect of the heat generated by the electronic device is canceled out and the electronic device can be tested at the predetermined temperature as prescribed in the specification.
