The individual parts and sub-assemblies must be sensibly designed to function safely and efficiently for the specified design lifetime without failure. In a design process of a main landing gear system, the kinematics/mechanisms analysis shall be first carried out as a primary task for feasibility of the gear retraction/extension with the satisfactory link paths. This paper presents the analytical kinematics analysis of a complex mechanism involving multiple four-bar linkages with multiple coupler points of the main landing gear (MLG) of CN-235 aircraft. The kinematics analyses were performed in order to figure out the overall link positions of the main landing gear mechanism and make scenarios of a deformed component from its designed geometry for possibilities of a lock failed position.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Complex mechanisms,Design concept,Design learning,Design process,Four-bar linkage,Gear mechanisms,Kinematics analysis,Mechanism analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Aircraft,Failure perspective,Four-bar linkage,Landing gear,Mechanism analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors wish to thank PT.
