ASOM Features

By using the kinematic elements you can already create multi-bar systems of infinite complexity and variety. Additionally, though, ASOM v7 also offers you syntheses for some of the most popular multi-bar linkage types.

Syntheses aid you in the design of multi-bar linkages based on a description of the desired movement. This description can be given in the form of desired points or planes (point plus orientation) for start and end of the movement (and sometimes in between).

Force Synthesis

Kräftesynthese
Force Synthesis

The force synthesis allows you to set certain holding force values at certain simulation times (or situations) and then keep them fixed.

Kinematic elements are the basic components that allow you to build a kinematic system. Their main function is to transmit movement, and for this they can be fitted with drives. They can also transmit forces, but they cannot be moved by forces.

Kinematik Stab
Bar

A bar is a rigid kinematic element with two joints (binary link). Even though it is depicted by default as just a straight line, it can functionally represent any element of arbitrary shape that shares these basic properties.

Kinematik Schubgelenk
Prismatic Pair

A prismatic pair consists of two elements: the slider and the guide. The slider is equipped with a joint and can slide along the guide, which itself can be rotated around a joint at one of its ends.

Kinematik Kulissenführung
Curved Guide

Like the prismatic pair, the curved guide also consists of a slider and a guide. The guide can be curved here though, since it is represented by a spline. The joint of the guide is connected to the guide by a rigid extension, the length of which can be set to zero though, if necessary. The joint of the slider, on the other hand, is situated directly on the slider. The guide can also be laid out as closed loop and even cross itself.

Kinematik Zahnradpaar
Gear pair

Gear pairs transmit a rotary motion, while reversing its direction and often changing its speed. During creation you will first have to choose the position of the joints the gears should be mounted on, followed by the gears’ point of contact. Depending on these inputs, the transmission ratio is computed.

Kinematik Riementrieb
Belt Transmission

Like the gear pair, the belt transmission is used to transmit a rotary motion, in this case by using a belt, though. This means that after its creation you can decide if you want to change the direction of the motion by crossing the belt, if the belt should be closed and, if not, if it should be brought around the other side of each wheel.

Kinematik Zahnstangenantrieb
Rack-and-Pinion

The rack-and-pinion converts the rotary motion of a gear into a translatory motion of a rack. It consists of three parts: pinion (gear), housing, and rack. Additionally it has two joints: one for the pinion and one on the rack.

Kinematik Loslager
Floating Bearing

The floating bearing limits a joint’s movement to a straight line. It can move any distance in either direction, but it will not be able to deviate from the straight line. The direction of the straight line cannot change during a simulation.

Kinematik Festlager
Fixed Bearing

With a fixed bearing you can fix a joint in place. Elements connected to it can still rotate around the joint, but the joint itself can no longer change position.

Kinematik Winkelfixierung
Fixed Angle

With the fixed angle, you can keep the angle between two elements connected by a joint constant. With this element you can also merge two separate binary links (with two joints each) to become one single trinary link (with three joints). This merging into a rigid body can be extended to an arbitrary number of elements.

With drives you can impose a motion onto a kinematic element. They can be used on a variety of couplers, but do not exert any force of their own, just the pure motion. To make a kinematic system capable of simulation, you need at least as many drives as the number of degrees of freedom in the whole system. If more drives than degrees of freedom are placed, no more than the number of the degrees of freedom may be active at the same time.

Antrieb Rotation absolut
Absolute Rotary Drive

The absolute rotary drive imposes a rotational movement on the coupler it is placed on.
