| Abstract: | Considered many non-linear contact relationships between the main components in diesel,a time domain simulation method was applied to assessment its shock response.In the assessment,some modeling principles of complex mechanical systems,such as diesel,were given.Also,the finite element models of main components in V6 diesel were established,and then,their shock response characteristics were analyzed in time-domain on the basis of BV043/85 criterion.The stress responses of main components showed the shock vu... |
