- 为了更准确反应行星架后壁区域本体力学性能，为解决 70 mm 厚标准试块无法准确反应行星架厚壁区域
本体力学性能的问题，浇铸不同壁厚的附铸试块，对比研究不同壁厚试块和本体的力学性能的差异。 结果表明，无论是
铸件本体还是附铸试块，力学性能都随模数增加而降低，当试块心部模数和本体心部模数接近时，力学性能也非常接
近。 对于厚壁铸件，如果没有合适的本体取样位置，可以通过浇铸和本体模数相近的附铸试块来评估本体力学性能。
In order to more accurately reflect the mechanical properties of thick-walled region of planetary carrier, cast-on
test blocks with different wall thickness attached to planetary carrier was cast, In order to solve the problem that 70 mm
thickness standard test block cannot accurately reflect the mechanical properties of the body in the thick-walled region of the
planetary frame, the attached test block with different wall thicknesses was cast, and the difference of mechanical properties
between the test block with different wall thicknesses and the body was compared and studied. The results show that the
mechanical properties of both the casting body and the test block decrease with the increase of modulus, and when the core
modulus of the test block is close to the core modulus of the test block, the mechanical properties are also very close. For
thick-walled castings, if there is no suitable body sampling location, the mechanical properties of the body can be evaluated
by casting attached test blocks with similar modulus to the body.
