Vibration modal analysis and hanger location optimization of automobile exhaust system

Research & Development of Suspension for Motorcycle;

To improve the lateral dynamic performance of a speed-raising locomotive running at a high speed,the lateral stability,ride index,lateral wheelset force and change in wheel load for a traction motor respectively elastically and rigidly mounted on the frame were compared and investigated based on analyzing the traction motor suspension designs of 2C0 speed-raising locomotives.

In order to get the distance limit under the condition that the cannon is pulled on intensified road,the fatigue life of a flexible part in cannon suspension device is studied.

Influence of the hanging orientation of cathode to the electrodepositing of diamond-nickel composite film;

Based on the idea of modeling, the paper reasonably predigests a complicated actual system, demonstrates the feasibility of hanging method in theory, studies connection between stability and influencing factors, and brings forward an improved method of design that can be regarded as academic basis for further experiments.

In order to eradicate the hidden trouble,the safety belt hanging devices can be placed on the top or side of the steel beam,and the safety belt can be always protected.

The Analysis of the test system of resonant hanging automobile;

A engineering algorithm of thrust loads for the hanging teetering rotor is presented on the assumption that first induced velocity distribution,first cyclic pitch motion and three harmonics of flap motion in this paper.
