图4-11 固定副约束

(1)部件engine_block与安装件body之间fixed约束。

•Joint Name(约束副名称):engine_kinematic;

•I Part :._my_engine.ges_engine_block;

•J Part :._my_engine.mts_body;

•Joint Type(约束副类型):fixed,即转动副,约束6个自由度;

•Active(激活):kinematic mode(运动学模式);

•Location Dependency:Delta location from coordinate;

•Coordinate Reference(参考坐标):._my_engine.ground.hps_engine_CM;

•Location:0,0,0;

•Location in:local;

•单击Apply,完成约束副._my_engine.jksfix_engine_kinematic的创建。(https://www.daowen.com)

(2)部件engine_block与crankshaft之间revolute约束。

•Joint Name(约束副名称):block_to_crankshaft;

•I Part:._my_engine.ges_crankshaft;

•J Part:._my_engine.ges_engine_block;

•Joint Type(约束副类型):revolute;

•Active(激活):always;

•Location Dependency:Delta location from coordinate;

•Coordinate Reference(参考坐标):._my_engine.ground.cfs_crankshaft_end;

•Location:0,0,0;

•Location in:local;

•Orientation Dependency:Delta orientation from coordinate;

•Construction Frame:._my_engine.ground.cfs_crankshaft_end;

•单击OK,完成约束副._my_engine.josrev_block_to_crankshaft的创建。
