摘要： PROBLEM TO BE SOLVED: To provide a method of analyzing the torsional vibration of a power transmission system by computing an absolute damping coefficient of a cylinder part and a relative damping coefficient between cylinders as values corresponding to a real engine so as to be reflected in a torsional vibration analysis of the power transmission system, and to provide an analyzing device, an analyzing program and a shafting device between the engine and a driven device.
SOLUTION: A system from the engine to the driven device is modeled into an inertial mass-spring system. The total damping energy, which is the vibration generating energy, balancing the vibration generating energy with the damping energy at a plurality of sets of resonance points of natural modes/frequencies is computed from a measured damping ratio and computed mode mass. The total damping energy is expressed as the sum of engine side absolute damping energy, relative damping energy and damping energy of an attachment on the driven device/shafting system. Engine absolute damping coefficients and a plurality of equations on the engine absolute damping coefficients are created from the measured results of the plurality of resonance points, and a plurality of simultaneous equations are solved to determine the engine absolute damping coefficient and engine relative damping coefficient.

摘要： PROBLEM TO BE SOLVED: To easily measure axial torsional vibration in an internal pump.
SOLUTION: A vibration detector 2 for detecting radial-directional vibration, and a sound detector 3 for detecting circumferential-directional vibration are attached to a cylindrical casing 6 for storing a motor for the internal pump. A vibration operation unit 15 conforms a dimension of a vibration waveform signal detected by the vibration detector 2 with a dimension of an acoustic waveform signal detected by the sound detector 3, and finds the axial torsional vibration of the motor, based on a difference between the both signals.

摘要： PROBLEM TO BE SOLVED: To operate the vibration analysis of the whole of a system having nonlinear elements surely in a short time with a simple structure by dividing the system into plural sub-systems taking nonlinear elements as boundaries, forming simultaneous motion equations on each sub-system so as to input the characteristics of the nonlinear elements, and obtaining a solution. SOLUTION: For instance, a vibration system is divided into two sub-systems taking a dry single plate clutch 2 of a 6×4 large-size truck as a boundary, from the clutch 2 to a vehicle body 16 is assigned as a sub-system 1, and from the clutch 2 to an engine 1 is assigned as a sub-system 2. On the sub-system 1, an equation of motion expressed by the model coordinate of the natural vibration of a drive system and a boundary freedom obtained by the static contraction of Guyan is formed, and on the system 2, after the equation of motion is set up considering the engine 1, the disk of the multistage clutch 2, and a torque change as external force, simultaneous motion equations are formed out of two motion equations so as to input the characteristics of the multistage clutch disk to obtain a solution. Thereby, torsional vibration analysis on the whole of the driving system can be conducted without conducting design based on experiment, experience, or the like.
