LMEC-7 Pohl's Pendulum

Lus piav qhia luv luv:

Nws yog tsim los ntawm kev vibration system, dampers, cranking qhov chaw thiab kis tau tus mob, theem lub kaum sab xis ntsuas qhov system, kev sim txheej txheem tswj thiab kev khiav hauj lwm qhov system, thiab lwm yam. Nws yog siv los kawm cov resonance tshwm sim los ntawm kev quab yuam kev co thiab damped oscillation thiab lwm yam kev sim.

Khoom cim npe

Kev sim

1. Kev vibration dawb (oscillation) sim.

2. Kev tshawb nrhiav kev vibration hauv qab-damped.

3. Kev tshawb nrhiav qhov tshwm sim resonance tshwm sim.

Nta

1. Txais coiled caij nplooj ntoos hlav tsau axis disc oscillation mechanism raws li lub hauv paus kev co lub cev.

2. Stepper lub cev muaj zog tsav los tsim kom muaj kev hloov pauv raws sijhawm.

3. Txais yuav incremental encoder yog ntsuas ntawm theem sib txawv.

4. Loj LCD zaub, cov ntaub ntawv ntsuas thiab saib yooj yim.

Zaub	240 × 160 dot matrix LCD, cov ntawv qhia zaub mov tsim, kev sim ua haujlwm thiab cov ntaub ntawv nug yooj yim, nrog cov ntaub ntawv khaws cia muaj nuj nqi.
