It is shown that the wheelset guiding system of linkage between axles of light tare weight can make the bogie have fairly good hunting stability and curve negotiation performance, so as to reduce wheelrail lateral force and the wheelrail wear.

In this paper,by using of the SIMPACK software, a model of the 6-axle locomotive is set up to simulate the testing of the 6-axle locomotive on the roller testing rig, so as to analyze the effects of track wheel radius, wheel tread gradient on the hunting motion stability of locomotives and rolling stock.

The controlled electro-mechanic damper is developed to avoid the occurrence of hunting instability and improve running speed of rolling stock.

Experiment on operation stability of an endurance test bed for automobile air conditioner compressors;

The problem of operation stability occurred in a lot of large power stations both in domestic and abroad,which is international topic.

Through analysis and comparison to some representative typical large_scale Francis_type HT of the same water head sect, domestic and foreign, analyzed the main parameters and operation stability of HT, put forth main parameters levels for HT of BHS, and also suggested some measures that ought to be adopted for improving operation stability.

According to the result of the operational stability test of Unit No.

The operational stability of butyric acid type fermentation was investigated in H2-producing process by fermentation.
