The multi-agent simulation system includes a plurality of back-end servers provided for each of a plurality of service systems and a plurality of agent simulators provided for each of the plurality of agents. Each of the plurality of service systems provides a service used in the target world. The plurality of agent simulators are programmed to simulate a state of each of the plurality of agents while causing the plurality of agents to interact with each other by exchange of first messages. The plurality of back-end servers and the plurality of agent simulators are programmed to simultaneously simulate a plurality of services by exchanging second messages different from the first messages.

Multi-agent simulation system and method

Speed reducer

In a rotation transmission mechanism that transmits the rotational driving force of a motor to a load-side member via a speed reducer, a strain wave gearing is used as the speed reducer, and the allowable load torque of members in the powertrain other than the strain wave gearing is greater than a predetermined upper-limit load torque. The allowable load torque of the strain wave gearing is dictated by the ratcheting torque, which is set so as not to exceed the upper-limit load torque. In an overload state, ratcheting is generated in the strain wave gearing, so that the strain wave gearing functions as a mechanical fuse. Other power transmission members can be protected from an overload state without adding a separate member such as a torque limiter.

Rotation transmission mechanism provided with strain wave gearing

An externally toothed gear of a dual-type strain wave gearing is provided with first and second external teeth having different teeth numbers, and a gap formed between these teeth as a cutter clearance area for tooth cutters. Where L1 is the maximum width of the gap, t1 is a depth from the tooth top land of the first external teeth to the deepest part of the gap, h1 is the tooth depth of the first external teeth, t2 is a depth from the tooth top land of the second external teeth to the deepest part, and h2 is the tooth depth of the second external teeth, any one of the following conditions 1 to 3 is satisfied:1=0.1&#x2212;0.351=0.91&#x2212;1.31, and2=0.32&#x2212;0.92&#x2003;&#x2003;Condition 1:1=0.1&#x2212;0.351=0.31&#x2212;0.91, and2=0.92&#x2212;1.32&#x2003;&#x2003;Condition 2:1=0.1&#x2212;0.351=0.31&#x2212;0.91, and2=0.32&#x2212;0.92&#x2003;&#x2003;Condition 3: It is possible to obtain a dual-type strain wave gearing in which wear resistance and tooth bottom fatigue strength are increased.

A drive unit for a hybrid vehicle that enables downsizing and cost reduction of an oil supply mechanism to be achieved. The drive unit includes: a first feeding line for supplying a first motor and a differential mechanism with oil discharged from a first oil pump; and a second feeding line for supplying a second motor with oil discharged from a second oil pump, the oil being supplied via an oil cooler that cools the oil. A passage between from the second oil pump to the second motor in the second feeding line and a passage between from the first oil pump to the first motor and the differential mechanism in the first feeding line, are independent of each other.

A restraint mechanism for limiting the movement of the flexible external gear of a flat strain wave gearing in the axial direction has a first restraining member installed in a floating state in a first recess and a second restraining member installed in a floating state in a second recess. The restraining member is able to limit the movement of the flexible external gear in the axial direction to a range in which there are no difficulties during actual use. Moreover, compared with when movement of the flexible external gear is limited using members that are disposed at fixed positions, it is possible to reduce the sliding abrasion that occurs between the flexible external gear and the first and second restraining members.

Flat strain wave gearing

A wave generator for a strain wave gearing makes a flexible externally toothed gear to flex into an elliptical shape and mesh with rigid internally toothed gears, and makes meshing positions of the flexible externally toothed gear with the both gears to move in a circumferential direction. On the inner side of a rigid plug of the wave generator, a plug support ring is secured and integrated. The rigid plug is formed from an iron-based material, and the plug support ring is formed from a high-rigidity material that is more rigid than the iron-based material. Since deformation of the rigid plug is suppressed, the wave generator provided with a large hollow part can be obtained.

A parking device includes a parking gear, a parking pawl, and a torsion spring. The parking gear is directly coupled to an axle. The parking pawl is pivotably supported by a fulcrum pin and provided with a claw configured to be able to mesh with a tooth space of the parking gear. The torsion spring is fitted on the fulcrum pin, with a first end of the torsion spring mounted on the parking pawl and a second end of the torsion spring mounted on a holding member that holds the fulcrum pin.

A case component of a transaxle includes: a bearing unit having a through-hole through with a shaft member is to be inserted; a matching surface unit having a matching surface on which another member is to be overlapped; bolt hole portions formed on the matching surface unit; bent wall portions, each having a V-shaped or U-shaped cross-section cut in a direction orthogonal to a straight line connecting a shaft center of the bearing unit and a shaft center of the bolt hole portions, each having a valley portion positioned on the straight line, and connecting the bearing unit and the respective bolt hole portions; and V-shaped portions, connected with the respective bent wall portions, provided on an outer circumference of the respective bolt hole portions, and protruding toward the bearing unit.

A wave generator of a flat-type strain wave gearing has an insertion member disposed between two wave bearings. The insertion member is pressed into an elliptical outer peripheral surface of a plug and is fixed thereto by an adhesive. An inner ring contact part of the insertion member is in contact with inner rings of the wave bearings from the direction of a center axis. When the flat-type strain wave gearing is in an operating state, the wave bearings can be prevented from moving relative to the plug in the direction of the center axis by means of thrust force acting on the wave bearings.

An information processing device includes: a pointing device; a display unit; and a processor configured to cause the display unit to display a first GUI component selected by a cursor and a second GUI component, calculate a displacement of an input position in a predetermined coordinate system, set a reaction area in the predetermined coordinate system, set a selection area in the predetermined coordinate system based on a second coordinate, set the reaction area as an identified reaction area, cause the display unit to display the second GUI component, corresponding to the identified reaction area, as selected by the cursor, and set the reaction area so that a distance between the first coordinate and the second coordinate, required for the selection area to overlap with the reaction area with the overlapping area exceeding the overlapping criterion, becomes a predetermined distance.

A cooling system for a power transmission unit that can cool a cooling site effectively is provided. The cooling system comprises: an oil pump; an oil cooler that cools the oil delivered from the oil pump; a first oil pipe for delivering the oil from the oil pump to the oil cooler; a second oil pipe for delivering the oil cooled by the oil cooler to a heat generating element. A housing chamber includes a high-temperature section where the heat generating element is arranged, and a low-temperature section. The second oil pipe is arranged in the housing chamber while passing through the low-temperature section, and an opening is formed on the second oil pipe in such a manner as to open toward the heat generating element.
