Design and Improvement of Die Casting Die for PQ35 Engine Bracket;

The three-dimensional model of the bracket is built by UG,and modal analysis is conducted on the 4G1 engine bracket through the software of ANSYS Workbench so as to identify the modal parameters of the bracket,the natural frequency and vibration features.

The application of topology optimization in Engine bracket design is aimed to improve the structure performance and get a lighter structure.

This paper introduces the measuring principle of a chassis dynamometer,employs a hypothesis test to conduct significance analysis on the experiment data of the tractive power of chassis dynamometer on the vehicle and the net horsepower of an engine bench test.

The paper introduces in detail the US diesel engine evaluation bench,and give some suggestions on domestic engine bench development.

Interfere is likely to lead lapes of infer-control system in running course of engine bench.

Light-weight design on engine support based on structural topology optimization method;

In order to further improve the structural design and realize the CAE standardization of the engine support,we adopt finite element software ANSYS to calculate and emulate the stress distribution,and draw out the stress and strain distribution maps in the paper.
