Abstract:This work has been performed to evaluate the strength of fixtures, which were attached to outer surface of propeller flask to prevent transient movement during filling and cooling stages at Ni-Al-Bronze casting of large marine propellers. Experimental work was carried out to evaluate forces exerted on flask fixtures by measuring strain changes of fixtures due to thermal expansion and contraction during casting processes. Numerical analyses were also made to verify the experimental results and finally to evalua… Show more
