Photoplastic Analyses of 3-D Plastic Strain Distribution in Gears
摆辗成形后的摩托车启动齿轮三维塑性应变场的光塑性分析

The rocking die forming process of motor gears, made of low carbon or low alloy steel, is simulated with a kind of photoplastic material polycarbonate. 3-D plastic strain distributions on meridian planes and any other round section are analyzed, both in spiral and rose rocking trail. It appears that the strain distribution in a spirally formed gear is more homogeneous and yields better results.
