elastic deflection การใช้

• DTV is usually attributed to the following causes : waviness and roughness of disc surface, misalignment of axis ( runout ), elastic deflection, wear and friction material transfers.
• It has strength / modulus of elasticity ratios almost twice those of 18-8 austenitic stainless steel, larger elastic deflections in springs, and reduced force per unit displacement 2.2 times below those of stainless steel appliances.
