摘要

PPROBLEM 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. PSOLUTION: 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.

要解决的问题：提供一种通过计算汽缸部件的绝对阻尼系数和汽缸之间的相对阻尼系数作为与实际发动机相对应的值来分析动力传递系统的扭转振动的方法反映在动力传递系统的扭转振动分析中，并提供一种分析装置，分析程序和发动机与从动装置之间的轴系装置。

解决方案：从发动机到被驱动设备的系统被建模为惯性质量弹簧系统。根据测得的阻尼比和计算出的模态质量，计算出总的阻尼能，该总阻尼能是振动产生能，它使振动产生能与自然模式/频率的多个共振点处的阻尼能达到平衡。总阻尼能量表示为发动机侧绝对阻尼能量，相对阻尼能量和从动设备/轴系上附件的阻尼能量之和。根据多个共振点的测量结果，创建发动机绝对阻尼系数和关于发动机绝对阻尼系数的多个方程式，并且求解多个联立方程，以确定发动机绝对阻尼系数和发动机相对阻尼系数。
