Although our six-bar syntheses strictly speaking only allow the specification of 2 plane conditions (plane = point and angle), it is still possible to design six-bar linkages in ASOM v7 to fulfill 3 (or in principle even more) plane conditions. Instead of using scripts to create only numeric displays in expressions, as shown in our
Although our six-bar syntheses strictly speaking only allow the specification of 2 plane conditions (plane = point and angle), it is still possible to design six-bar linkages in ASOM v7 to fulfill 3 (or in principle even more) plane conditions.
Using three brief examples (car seat, rear hatch and spoiler), we demonstrate how car manufacturers and suppliers can use the kinematics software ASOM v7 to solve typical industry-specific problems.
Basic kinematics example of a folding dining table. The middle plate in the table shown here is automatically lifted into the center position by four-bar systems on each of the two sides. The two partial systems are kinematically independent of each other.
This example illustrates a part of the kinematics of a hospital bed with two different actuators or spindle drives, one for the height adjustment of the entire bed and one for lifting of the foot area.
Basic kinematics example for self-locking under force-dependent friction. Friction occurs between a vertical guideway and a fork with a mass in the center of gravity and two contact points on the guideway. This friction is described in each case by a coefficient of friction or a friction value in the two sliding bearings, which, for
Basic kinematics example for a hinge system.
Here, a block and tackle is combined with a linear guide. The ratios between stroke and path length and the required forces are computed in compressed time.
This example created with the kinematics software ASOMv7 shows how the normal forces in the two table legs change or adapt when a horizontal force is applied to move the table.
Idealized kinematics example with a block that rests on a plane and can be moved with a corresponding actuating force.
