Pendulum wave museum exhibit

An enclosed pendulum wave exhibit turns a row of swinging bobs into changing patterns. Visitors follow individual oscillations and the shifting shape of the whole array, introducing period and phase through a physical demonstration designed for a museum gallery.

THE ACTIVITY & MECHANISM

Watch the pendulums form changing patterns

Pendulums with different periods gradually change their timing relative to one another, so a row of simple swings appears to form travelling patterns. Visitors can track one bob and then the whole array through the clear enclosure. The group pattern arises from changing relative phase rather than a wave travelling along a connected string.

01
Start
Use the front control as directed by the exhibit instructions, then watch the pendulum array.
02
Follow
Choose one bob and follow its repeated swing before looking across the whole row.
03
Compare
Describe how the group pattern changes while each pendulum continues its own back-and-forth motion.

REFERENCE & PROJECT SCOPE

Reference specifications.

Use the reference dimensions and operating information to plan the exhibit. The agreed project drawings define the supplied configuration, installation interfaces and service access.

L × W × H: 1,800 × 750 × 1,550 mm
Exhibit theme: Fundamental Science
Visitor activity: Start · Follow · Compare
Reference operation: A front push control starts the enclosed pendulum demonstration. Follow one bob, then compare the changing pattern across the row. Agree the start, stop and return sequence for the supplied controller.
Power & supply: Powered versions can be configured for 110/220 V AC, 50/60 Hz. Provide access to the cabinet controls, viewing enclosure and pendulum supports. Confirm the power connection for the start mechanism or lighting and the final floor fixing arrangement.
Reference construction: The reference combines suspended bobs, an overhead support, a transparent enclosure and a cabinet. Confirm the bob alloy, enclosure material and cabinet finish in the supplied material schedule.
Configuration options: Appearance, interpretation language, controls and installation arrangement by project agreement
Daily operating schedule: 8 hours per day
Scheduled maintenance: Every 30 days
Factory dispatch lead time: 30–120 calendar days after design approval and receipt of the deposit. Transit time is additional.
Minimum custom order: One exhibit

Overall reference product, including base or cabinet. Installation and service clearances are additional.

Reference configuration notes

Physical array: Suspended bobs hang in a row from supports at different heights.
Viewing enclosure: Clear panels enclose the pendulums above the cabinet.
Visitor control: An illuminated push control sits on the front instruction strip.

Customisation, installation & support

01Cabinet envelope: Owner reference: 1800 × 750 × 1550 mm, L × W × H, including the cabinet. Add visitor and service space.
02Viewing angle: Keep the full pendulum row visible from the main approach and allow visitors to compare frontal and oblique views.
03Gallery lighting: Position lighting to reduce reflections on the enclosure and preserve contrast around the moving bobs.

Delivery, installation & after-sales terms

Payment: A 50% deposit is payable after the contract is signed. The remaining balance is paid after acceptance and before dispatch, so full payment is received before dispatch. Payment methods are agreed in the contract.
Packaging & transport: Metal shipping cases or multilayer wood-panel shipping cases. Transport arrangements and costs are agreed to suit the project.
Materials & painted finish: Common material options include Q235 steel, stainless steel, aluminium alloy, PVC, acrylic, engineering plastics. The combination is selected for each configuration. Marine anti-corrosion paint with a piano-gloss automotive paint finish. Applied to painted parts.
Typical power · powered versions: Standard products: 100–500 W; oversized installations: 1,000–5,000 W. Typical ranges for powered versions. Confirm the selected model and final connected load.
Product maintenance: Routine checks should cover suspension alignment, bob clearance, start-control condition and enclosure fixings. Keep the viewing panels clean and provide access to the start assembly and suspension points.
Installation & training: Complimentary training is available on site or remotely, according to project needs. If installation or on-site after-sales service is not included in the product price, the customer pays the actual travel expenses incurred, unless the contract provides otherwise.
Factory acceptance & handover: Mid-production and pre-dispatch checks are provided. Factory acceptance can take place in person at the factory or through acceptance videos. Installation and operating videos, written installation and operating instructions, drawings and a spare-parts list are provided.
Complimentary parts: 24 months of complimentary spare-parts support, starting when the exhibit is handed over for use. Covers faults not caused by the user. User-caused or deliberate damage is excluded. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
Warranty & repair labour: The whole-exhibit warranty period and repair labour scope and charges are agreed in the contract.

Can we discuss a prototype or sample for a custom version?

Yes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.

How prototype testing & samples work

What should the exhibit explain?

Focus interpretation on repeated oscillation, different periods and changing relative phase. Visitors can connect the movement of one bob with the pattern of the array.

How does this relate to the portable STEM pendulum wave?

This page covers the enclosed cabinet version for museum installation. The portable STEM product is a separate classroom format and should be specified through its own product page.

What do the images and videos show?

The gallery labels photographs, video frames, renderings and the dimension drawing. Physical footage is identified separately.
