Filed: 1994-10-28
Abstract: PURPOSE: To solve such a problem where the calculation time is increased due to a flow into taking consideration in an analysis method/system that is applied to the vibration of a structure at a flow site. CONSTITUTION: The matrices constructing a structure-flow coupled vibration equation are effectively calculated by the parallel processing. That is, the coupling matrices M, C, K, L1 , L2 , L3 , L4 , L5 , H, D and Q of a structure and a fluid are calculated by the parallel processing. Then, the parallel processing is applied to the matrices M, Q, K, and H which require the triangular factorization Furthermore the matrix operations M<-1> K... Q<-1> H contained in a motion equation of the entire system are calculated by the parallel processing and then calculate again by changing the flow velocity. Then a stable critical flow velocity is obtained by the eigenvalue calculation. The effects of the shearing stress and the compressibility due to the viscosity are combined together and analyzed.  The calculation time can be shortened since the component matrices of the motion equation are calculated by the parallel processing.

Title: Confluence control system for carrier
Inventor: SAKAMOTO TAKASHI
IPC: G05D1/02
Filed: 1991-10-15
Abstract: PURPOSE:To avoide the collision between carriers in a confluence area.

At this time, the amount of energy enough to fuse the entire part of the protruded length is applied.

CONSTITUTION:At the time of normal running wherein an acceleration pedal and a brake pedal are not stepped, a switch (SW)16 is opened and SW24 is closed. The output of a wheel speed sensor 21 is amplified by an amplifier 22, converted by a F/V converter 23 and held to a holding circuit 25 to determine a car speed V which is, in turn, outputted from a subtractor 20 as it is. When a brake is stepped, SW 16 is closed and SW 24 is opened and the car speed V is outputted from the holding circuit 25. The output of a G sensor 11 is amplified by an amplifier 12, passed through LPF13, 14 and subtracted by a subtractor 15 to determine acceleration alpha along a surface 2 and said acceleration alpha is integrated by an integrator 17 to determine integral alphadt. Next, V-integral alphadt is operated to determine the car speed. By this method, the earth speed of a vehicle can be accurately calculated regardless of pitching.
