Abstract:

In the paper the formulas of computing the grabing force about the wood grab in central drive form at two working conditions are deduced.The optimal design about it is studied and discussed, and the program is worked out. Some practical results are obtained.

Key words: Wood grab, Maihematical model, Optimal design
