This video shows an example for the export of simulation data from ASOM v7 to Excel. This export is freely configurable and data can be written into specifically targeted locations in existing or pre-configured Excel files, so that no manual changes in existing Excel files are necessary.

An import of positional data from Excel is also possible. The data can, depending on what is needed, be imported as simple point cloud, as polygon, or also as a curved guide rail (as a spline with multiple options).

This example illustrates one possible workflow for the export and import of data. The corresponding ASOM project and the associated Excel file can also be downloaded.

Another simplified example for a pedestrian protection kinematic, this one based on a different functional principle.

The actuator is activated accordingly, in case of an impending frontal crash with potential pedestrian involvement, and generates as promptly as possible - meaning even before the actual impact happens - an increased safety clearance above the engine block.

With ASOM, corresponding kinematics can be conceptualized, assembled, simulated, analyzed and interactively optimized.

Example illustrating the kinematic analysis and interactive optimization of a toggle switch using the kinematics software ASOM v7.

In this example the operating forces for a toggle switch are analyzed. Different cases are analyzed at the same time in the same project:

  • switching on without friction
  • switching off without friction
  • switching on with simplified friction
  • switching off with simplified friction

The subsequent manual optimization of the operating forces by changing the contour takes into account all four cases at the same time and is still very easily accomplished.

In this example, a complete force design for a spindle drive to actuate a tailgate is presented. For this purpose, holding forces are computed under different ambient conditions such as inclination changes, snow loads, friction, clutches, overload cases, safety margins, efficiency factors, etc.

To correctly observe also direction-dependent influences, the complete opening and closing sequences are evaluated in real time at the same time using compressed time simulation.

The spindle drive consists of a fully configured spindle and two fully configured springs as energy storage components (one main support spring and one pop-up spring).

Everything presented here for a simple hinge can easily also be applied to an arc hinge, a four-bar system, or a different multi-bar system.

Example for a pedestrian-protection kinematic (the representation is simplified here) with a four bar system and an actuator. The animation includes two parts: Normal opening and closing process and the protection-activation process (in slow-motion).

The use of the Kinematic Synthesis feature in ASOM enables the user to modify any bearing positions without losing the conditions for the desired position of the hood.

In this example of a four bar system generated 'on-the-fly' it is demonstrated how the use of a group of several alternative manual force elements makes it possible to kinetostatically determine the required forces (balance forces / manual forces) at several contact points simultaneously, even while these points are modified, singly or as a group.

In this example, the kinematics and some selected kinetostatic forces of an elliptical home trainer are analyzed in ASOMv7.

To accomplish this, the forces exerted by the person are passed into the system and are balanced kinetostatically by countering forces and torques in the flywheel. One bearing force is determined as an example, and by way of a specially generated slider the (simplified) power input from the person can be varied interactively.

The kinematics are divided into three connected layers:

  1. Left home trainer layer
  2. Person
  3. Right home trainer layer

This example illustrates the principle of an interactive Two Point Synthesis carried out with the kinematics software ASOMv7 for a multi-bar system.

In this example, an object (here: the ball) is transported from one desired position to a second desired position by way of the coupler of a four-bar system. After the initial construction of the four-bar system the second desired position is intentionally changed and the system is automatically modified accordingly by the synthesis process. All of this can be done in a highly interactive way and works in real-time (or rather: compressed-time). The resulting linkage is updated immediately.

Example for the handling of a gas spring and its integration as an energy storage for a car hood, using the kinematics software ASOMv7.

This example briefly illustrates various possibilities and features to include a gas spring in a tailgate or front hood design with four-bar kinematics. This includes the following possibilities:

  • to use and include a desired gas spring in a targeted way, using the gas spring synthesis
  • the declaration and modification of the synthesis planes (initial plane as well as target plane, with the gas spring properties computed in 3D if needed)
  • the SIMULTANEOUS consideration in force computation of different inclinations, optional loads like e.g. snow load, friction effects, movement directions, manual force action points, temperatures
  • use of ideal or real gas laws (VdW: Van der Waals, BWR: Benedikt Webb Rubin, BWRS: Benedict Webb Rubin Sterling, always with the possibility to modify even the underlying modeling constants of these gas laws)

An example for the interactive calculation of a truss (here: a simplified bridge) with the kinematics software ASOM v7, considering the following features:

  • a truck drives over the shown bridge
  • both wheel pairs (front and rear) transmit partial loads independently
  • all results for all parts of the bridge (e.g. bearing forces and tensile/compressive member forces) are immediately available for the whole distance of travel
  • changes of the truck load are considered automatically
  • on changes in truss structure all results are updated immediately

It is also shown how the kinematic constraints and the acting forces and masses for the system were entered

Highly interactive multi-position synthesis - in this case: three position linkage synthesis - with the kinematics software ASOMv7.

An example for the behavior of a kinematics simulation, in this case an interactive three position synthesis for a four-bar linkage in ASOM v7.

The positions are visualized by predefined markers, the user just catches these when entering the synthesis conditions. The corresponding repositioning of the joints of the kinematic system is carried out automatically and immediately by ASOM.

Even after finishing the synthesis, the user has the freedom to reposition individual joints. Once again, ASOM takes care of the repositioning of the other joints in real time, to keep the requirements (i.e. to run exactly through the three desired orientations) of the synthesis satisfied.

In this tutorial the basics of how to measure important kinetostatic quantities like e.g. holding forces and bearing loads are explained.

It is based around a simple four-bar system, with a mass and a force on the coupler, where two alternative holding torques have to be determined. The instantaneous center of movement is used to check the correctness. After that, a joint force and its components are determined for one of the joints.

ASOM offers several highly interactive real-time synthesis features like point syntheses and position syntheses (2 and 3 conditions) for one-bar, four-bar and six-bar mechanisms and also slider-crank systems. This tutorial picks two syntheses as an example to show the possibilities for working interactively while creating a kinematic system (or even after creating it) to suit your needs and constraints.
