<p>A dynamic simulation method for a natural frequency of a vehicle is disclosed. In an embodiment, the method of the present invention comprises the processes of: making a dynamic model of an engine, a body of a vehicle, and wheels of the vehicle; inducing a dynamic equation on the basis of the dynamic model, and obtaining an operation expression which can calculate a natural frequency according to a characteristic input value of the engine, the body of the vehicle, and the wheels of the vehicle as a result value from the dynamic equation; making and providing a program which can calculate the natural frequency by using the operation expression; and entering the characteristic input value of the engine, the body of the vehicle, and the wheels of the vehicle into the program, running the program to execute the operation process accordingly, and displaying the calculated result value of the natural frequency. The present invention aims to provide a dynamic simulation method for a natural frequency of a vehicle for analysis of a natural frequency of the vehicle including an engine mount which can play a great role in determining the direction and concept of an engine mount within a short period of time in the early stage of development of the vehicle.</p> |
