在對制作機(jī)器人的材料選擇問題上，
大型機(jī)器人模型制作廠家認(rèn)為設(shè)計(jì)人員通常主要考慮3個方面:使用要求、工藝要求和經(jīng)濟(jì)要求。根據(jù)材料的使用要求，選擇材料的一般原則有:
In terms of material selection for robot manufacturing, large robot model manufacturers believe that designers usually consider three aspects: use requirements, process requirements and economic requirements. According to the use requirements of materials, the general principles for selecting materials are:
(1)零件尺寸取決于強(qiáng)度，且尺寸和重量又受
(1) The size of the part depends on the strength, and the size and weight are affected by
到某些限制時，應(yīng)選用強(qiáng)度較高的材料。在靜應(yīng)力下工作，應(yīng)力分布均勻，如拉伸、壓縮和剪切的情況下，宜選用組織均勻，屈服極限較高的材料;在變應(yīng)力下工作的零件，應(yīng)選用疲勞強(qiáng)度較高的材料。
When reaching certain limits, materials with higher strength shall be selected. When working under static stress, the stress distribution is uniform, such as in the case of tension, compression and shear, the material with uniform structure and high yield limit should be selected; Parts working under variable stress shall be made of materials with high fatigue strength.
(2)滑動摩擦力工作的零件，應(yīng)選用減摩性能
(2) Friction reducing performance shall be selected for the parts working with sliding friction
好的材料;在高溫下工作的零件應(yīng)選用耐熱材料;在腐蝕介質(zhì)中工作的零件應(yīng)選擇耐腐蝕材料。
Good materials; Parts working under high temperature shall be made of heat-resistant materials; Corrosion resistant materials shall be selected for parts working in corrosive medium.
材料的各種性能指標(biāo)中.只取其中之一(如強(qiáng)度極限、疲勞極限等)作為選擇材料的依據(jù)是不合理的，由于減輕質(zhì)量常是設(shè)計(jì)機(jī)器人的主要要求之一，故可以采用質(zhì)量指標(biāo)對零件進(jìn)行評定，然后選擇合適的材料。
It is unreasonable to take only one of the various performance indicators of materials (such as strength limit, fatigue limit, etc.) as the basis for selecting materials. Since reducing mass is often one of the main requirements for designing robots, quality indicators can be used to evaluate parts and then select appropriate materials.
選材方法：選取何種材料構(gòu)成其結(jié)構(gòu)本體是詳細(xì)設(shè)計(jì)中必然要遇到的問題。一個結(jié)構(gòu)件的設(shè)計(jì)需要從材質(zhì)、剖面結(jié)構(gòu)、構(gòu)建組合形式等方面加以考慮，以便妥善應(yīng)力、變形、質(zhì)量、固有振動頻率等問題。
Material selection method: it is an inevitable problem in detailed design to select which material to form its structure body. The design of a structural member needs to be considered from the aspects of material, section structure, construction and combination form, so as to properly solve the problems of stress, deformation, mass, natural vibration frequency, etc.
