Webdynamic stiffness. 2. Measurement method2 The measurement method for the determination of dynamic stiffness is defined in ISO 9052-1 [2]. Here, a mass representative for typical floating floors is used to impose a static load on a sample of the material to be measured. The mass is excited, and from the resonance frequency f res WebFor a system with two masses (or more generally, two degrees of freedom), M and K are 2x2 matrices. For a system with n degrees of freedom, they are nxn matrices.. The spring-mass system is linear. A nonlinear system has more complicated equations of motion, but these can always be arranged into the standard matrix form by assuming that the … WebThe dynamic stiffness method (DSM) is proposed for vibration transmission from a machine with three degree of freedoms (DOFs) to its supporting beam structures. ...
