| Abstract: |
| From the Lagrange's equation, the dynamic model of the mounting system of an engine is established.The Cholesky factorization of the mass matrix is made on the generalized coordinates.Based on the energy distribution matrix and engineering constraints, the support parameters are optimized and solved by the principle of least squares.The feasibility and effectiveness of the optimization method are proved by the result of dynamic simulation, through the vibration excitation source analysis of the engine. |
