AI Technical Summary
Existing mechanical systems lack the ability to provide defined temporally asymmetric impulse excitation for investigating reproducible net deviations of position or force quantities under constant mean energy input, and fail to compare symmetric and asymmetric excitations under identical energetic conditions.

Enables reproducible net deviations of system-internal or external force or position variables under specific operating parameters, allowing for the investigation of dynamic force superpositions and phase-dependent coupling effects.

Abstract
Description
1. Technical field
[0001] The invention relates to a mechanical system with at least one oscillator, in particular a multi-mass oscillation system, which is operated by temporally structured pulse excitation.
[0002] The system serves to investigate dynamic force superpositions and phase-dependent coupling effects within classical mechanical framework conditions. 2. Purpose of the invention
[0003] The object of the invention is to provide a mechanical system that allows a defined temporally asymmetric impulse excitation and enables the investigation of reproducible net deviations of position or force quantities with constant mean energy input per cycle.
[0004] In particular, a platform should be provided that allows differences between symmetric and asymmetric excitation to be investigated comparably under identical energetic boundary conditions. 3. Solution
[0005] The task is solved by a mechanical system with the following features: at least one mechanical oscillator, a phase-triggered impulse excitation unit, a temporally asymmetric structure of energy input, constant average energy input per cycle, optionally several mechanically coupled modules, as well as sensors for the synchronous acquisition of relevant system parameters.
[0006] The impulse excitation exhibits a short excitation phase with high power density and a longer feedback or loss phase.
[0007] The average energy input per cycle remains constant.
[0008] Due to the temporal structuring of energy input, reproducible net deviations of system-internal or external force or position variables can occur under certain operating parameters. 4. Brief description of the drawings Fig. Figure 1 schematically shows a system with a single oscillator and asymmetric pulse excitation. Fig. Figure 2 shows an embodiment with two mechanically coupled modules. Fig. Figure 3 shows an embodiment with integrated sensors for recording internal and external system parameters. 5. Example of Implementation 5.1 Single Module
[0009] In a preferred embodiment, the system comprises a mechanical oscillator (1) consisting of a mass (2) and an elastic element (3).
[0010] A pulse generator (4) acts on the oscillator in a phase-synchronized manner.
[0011] The excitation takes the form of short impulses with high power density.
[0012] The excitation phase is followed by a longer feedback phase, in which the system releases energy under dissipative influences.
[0013] The average energy input per cycle is kept constant via the control unit. 5.2 Multi-module system
[0014] In another embodiment, several modules are mechanically coupled.
[0015] A first module (10) and a second module (20) are connected via a coupling element (30).
[0016] The coupling allows for a phase-dependent interaction between the modules.
[0017] The phase of the impulse excitation is adjustable, allowing for the investigation of constructive or destructive superpositions of the dynamic forces. 5.3 Sensors
[0018] At least one sensor (40) is provided for recording the system states.
[0019] This can be designed as a force sensor, displacement sensor, acceleration sensor or a combination thereof.
[0020] The sensors are connected to a data acquisition unit (50) which enables cyclically synchronous measurement for pulse excitation.
[0021] In an extended embodiment, additional sensor units (41), (42), (43) may be provided.
[0022] In this case (41) it can be implemented as a module-specific sensor unit within a module (10) or (20).
[0023] The sensor units (42) and (43) can be used to detect external or environment-related system variables.
[0024] Furthermore, a central stabilization unit (60) can be provided which monitors or synchronizes the phase position of the modules (10), (20).
