Automotive & commercial vehicles
Pedestrian protection, tailgates, spoilers, pedal assemblies, door handles, folding seats and much more. ASOMv10 calculates the force and torque requirements with springs, gas springs, friction and inertia.
Applications
Kinematics is at work in every industry
Whether seat adjustment, tailgate or hospital bed: ASOM is used wherever joints, springs and drives work together. Short videos show how ASOM solves typical real-world tasks.
Industries
Move the examples yourself
From vehicles to furniture to care beds: with ASOM, you design such motions and know the required forces before the first prototype is built.
Furniture & fittings
Office chairs, cabinet doors, folding door systems, hinges, folding tables and much more. In ASOM, you see the manual force curve over the entire opening motion and immediately recognize the angle from which a flap opens by itself.
Other industries
Care beds, wheelchairs, aircraft overhead bins, pulley blocks, projection screen lifts and much more. In ASOMv10, you model gears, racks and belt transmissions as well as sliding and rolling contacts.
Simplified models to try out.
Example videos
ASOM in action
The videos show real-world tasks and basics in just a few minutes. Filter by industry or product.
2:10
Tailgate with gas springs
Two gas springs whose force depends on temperature and direction, plus a parcel shelf on a cord. ASOMv10 shows all manual forces for opening and closing in one diagram.
2:29
Manually operated car seat
A hand lever adjusts the seat stroke by stroke. ASOMv10 plays back the strokes automatically and shows the manual force for different seat occupancies in one diagram.
1:40
Motor-driven car seat
An electric motor moves the seat to all extreme positions. ASOMv10 shows torque and power for different seat occupancies – and immediately what difference a torsion spring makes.
2:11
Pedestrian protection on the front hood
A hood mechanism for normal opening and for pedestrian protection. You examine each section of the motion sequence individually.
5:01
Flush-mounted door handle
A retractable handle with three specified positions. Two syntheses hold them in place while you move bearings, and ASOMv10 calculates eight drive cases at once.
3:43
Wankel engine
Constraints fix the gear ratio at 2 : 3. The trajectories of the rotor apexes form the housing contour – even when you change the rotor shape.
1:15
Wankel engine variants
Rotors with three to six apexes compared, each with the matching gear ratio. The trajectories of the rotor apexes form the housing contour.
1:32
Piston of a two-stroke engine
At 6,000 rpm, inertia matters. ASOMv10 calculates the joint and bearing forces with connecting rod, counterweight and piston.
3:03
Truck lift gate
Two hydraulic cylinders open the gate and raise and lower the platform. ASOMv10 combines the partial movements into one motion sequence and calculates the bearing forces with friction.
4:43
Step ladder for a motorhome
Two mechanisms for the same ladder: scissor kinematics and a parallelogram linkage. ASOMv10 designs both by synthesis and compares the required torques.
2:41
Kitchen cabinet flap
Set the tension springs on a six-bar hinge so that a 2–8 kg flap opens by itself from about 15–20°. ASOMmini shows the manual force curve.
2:26
Door closer
How much force is needed at the handle or directly at the door? The inner workings of the door closer are captured in a programmable torque, so the model stays lean.
3:13
Hospital bed with spindle drives
Two drives that model spindle drives adjust the height and the foot section. ASOMv10 calculates drive and bearing forces in real time, with friction in all joints and guides.
1:24
Aircraft landing gear with bearing friction
How much does friction change the cylinder force during deployment and retraction? ASOMv10 takes joint friction into account and compares the cylinder force with and without friction.
3:05
Pick-and-place mechanism
A parallel mechanism with two degrees of freedom: you specify the trajectory, and ASOMv10 provides the angle, speed and torque of the drives, including inertia effects.
3:08
Rolling bridge
Element shadows show the motion at a glance, without playing it back again. You assemble new movements from existing sections.
0:42
Excavator arm
Three linear drives, one per degree of freedom, move the boom, stick and bucket. Their motion profiles are coordinated with one another.
3:57
Umbrella
A pressure spring between the sliders opens the umbrella by itself. ASOMmini shows manual force and joint forces in real time, even with a modified spring characteristic.
3:19
Two-point synthesis
A four-bar linkage guides a ball from the start position to the end position. Move the end position, and the synthesis adapts the linkage in real time.
3:35
Symmetrical six-bar linkage for a door
A six-bar linkage guides a door, with the joints arranged symmetrically. The synthesis is built from constraints alone, and the start and end positions remain adjustable.
4:18
Joint friction
How much force does friction cost? With a pin diameter and a friction coefficient for each joint, you compare manual and joint forces with and without friction.
2:15
Friction on an inclined plane
A block on an inclined plane: the holding force when raising and lowering, with and without friction. Using constraints, you quickly check many variants.
2:31
Kinetostatic sensor field
Where should the hand apply force? ASOMv10 shows the manual force for many application points at once in one diagram – even while you move the points.
1:10
Sliding and rolling: circle on contour
A circular shape slides on a contour of any shape or rolls along it. The video shows both cases, precisely simulated in ASOMv10.
1:11
Sliding and rolling: contour on contour
Two contours of any shape slide or roll precisely on each other. Unlike with the circle, the moving part is also freely shaped here.
3:35
Four-bar linkage step by step
From a blank sheet to a fully rotating four-bar linkage with bearing forces and friction – the whole process in ASOMmini.
1:25
Four-bar linkage with manual force
The manual force element shows in real time how the required manual force changes when you move the application point, a bearing or the center of gravity.
2:29
Drive functions
A rotating motion becomes an oscillating motion. You shape the motion profile directly in the diagram, section by section.
0:56
Roller follower
A roller follower couples a four-bar linkage and a one-bar linkage. The cam curve follows every change immediately and can be exported as a list of points.
1:56
Chebyshev straight-line linkage
A Chebyshev four-bar linkage guides a point along an almost straight line: with a coupler length of 20 cm, the straight section lies within a corridor of about 1 mm.
