With the continuous improvement of living standards , increasing the overall performance of the car . Which reduce the vibration intensity to reduce the noise level to improve the ride comfort is one of the most important , but also by more and more attention . As the important part of the car , the engine , in addition to determine the vibration generated by its own working principle , but also to withstand the vibrations generated from the external excitation . Occurs when the engine of a modal frequency excitation frequency is close to resonance , leading to large bending and torsional deformation , a significant impact on engine performance , reliability , and noise as well as vehicles traveling ride comfort . The body is the skeleton and shell of the engine , and a lot of spare parts and auxiliary systems are installed in the body , both to be load-bearing body , but also can withstand the strength bolts tightened local tremendous compressive stress . So , body rigidity and dynamic characteristics of the improved and engine product quality , an important subject . By the finite element analysis of the body , and draw the primary frequency distribution in the body , and thus the body's stiffness analysis . Modal test analysis of the body , to identify some of the body's inherent vibration characteristics , to show the distribution of body deformation and stress concentration sites on the computer , verify that the finite element analysis of the results . Calculated based on the finite element analysis , modal test results , as well as the study of the dynamic characteristics of the body , a comprehensive analysis of diesel engines machine layout and structural features of the structure of the body to evaluate the proposed local improvement design . Finite element computer model of the body according to the improved gravimetric analysis, to verify the effect of improved body . The results show that the improved body stiffness of the model has been greatly improved .
