This paper presents a transient vibration analysis of a nonlinear full-vehicle. The full-vehicle model consists of a powertrain, a trimmed body, a drive line, and front and rear suspensions with tires. It is driven by combustion forces and runs on a road surface. By performing time-domain simulation, it is possible to capture nonlinear behavior of a vehicle such as preload due to gravitational force, large deformation, and material nonlinearity which cannot be properly treated in the conventional steady state analysis. In constructing a full-vehicle, validation process is essential. Validation process is applied with respect to the assembling sequence. The validation starts with component levels such as tires, springs, shock absorbers, and a powertrain, and then the full-vehicle model is constructed. Model validation is done in two aspects; one is model accuracy and the other is model efficiency.

This paper describes a simulation procedure to calculate a torque converter performance. The study focuses the validity of a solution and the handiness of the procedure. A comparison of the numerical solution and the experimental solution proves the model validity. Moreover, handiness is achieved by using commercial code with automatic unstructured mesh generating techniques. With suggested procedure, a complete analysis is carried out relatively fast. And an steady state interaction can be analyzed between three moving elements.
