SUBHARMONIC RESONANCES IN THE HYDROMECHANICAL TRANSMISSION OF THE WHEELED CHASSIS
Trans Motauto World, Vol. 1 (2016), Issue 2, pg(s) 31-35
In the article on the basis of the developed mathematical model the dynamics of the highly nonlinear system is investigated, consistent patterns of resonant mode occurrences are established, which is experimentally confirmed. It is established that one of the main reasons for high dynamic loading and HMT elements durability reduction is subharmonic resonances caused by close agreement of frequencies of free nonlinear system fluctuations with multiple value of frequencies of diesel engine disturbances. On the basis of the new consistent patterns, the area of stability and parameter move direction is defined for its provision. The offered damper design is synthesized for significantly reducing HMT dynamic loading.
