Abstract: The steering column is one of the important parts in the automobile steering system. Both traditional automobiles or new energy vehicles cannot do without the steering column. The cost of the steering column is its core competitiveness. In view of the increasingly competitive automobile market environment, it is necessary to optimize the structural design of the steering column to reduce costs. Combined with the structural characteristics of the steering column, this paper designs a handle cam-type steering column, and conducts finite element analysis and simulation on the natural frequency and static collapse performance of the column. Manual samples are made for test verification. Through simulation and experimental research, it is shown that the natural frequency and static collapse performance of the handle cam-type steering column can meet the column test requirements.

Key words: handle cam type steering column; finite element analysis; steering column design; experimental verification
